Open Source Tools: Audio/Music
1
Amarok
Replaces:
iTunes
This audio player lets you listen to music, creates playlists, displays

attractive as iTunes. Operating System: Windows, Linux, OS X.
2
Songbird
Replaces:
iTunes
You can't use Songbird on your iPhone or iPad, but you can use it
on your PC or smartphone to set up playlists, listen to audio, stream

Linux, OS X.
Open Source Tools: Backup
3
Areca Backup
Replaces:
Norton Ghost
This simple yet flexible backup manager offers both compression
and encryption capabilities, and it archives files locally, over a
network, or online via FTP or FTPS. It offers most of the same features
as Ghost, except it doesn't integrate with a full security suite, and it
doesn't support Blu-Ray. Operating System: Windows, Linux.
Open Source Tools: Browsers
4
Chrome
Replaces:
Internet
Explorer
The big advantage Google's browser offers over the one from
Microsoft is speed. It's fast to start up, fast to load pages, and fast
to run Web apps. Unlike other browsers, it uses a combination Web
address/search bar and simplifies the browsing experience in other ways
as well. Operating System: Windows, Linux, OS X.
5
Firefox
Replaces:
While not as fast as Chrome, Firefox offer faster performance
than Internet Explorer, as well as excellent security features. It
includes a lot of personalization features and more than 6,000 add-ons
so that you can make your browser work the way you want it to. Operating
System: Windows, Linux, OS X.
Open Source Tools: Compression
6
7-zip
Replaces:
WinZip
While WinZip offers a fancier interface and more menu options,
7-zip lets you create 7z files with a higher compression rate, which
means it creates smaller files. 7-zip also reads and writes WinZip
files, as well as a number of other popular compression formats.
Operating System: Windows, Linux, OS X.
7
PeaZip
Replaces:
WinZip
Unlike WinZip, PeaZip can save files in seven different formats

Windows, Linux, OS X.
9
MindTouch
Replaces:
Sharepoint,
IBM Lotus

editions add more features. Operating System: Windows, Linux.
Open Source Tools: Customer Relationship Management (CRM)
10
SugarCRM
Replaces:
SalesForce.com
Like SalesForce.com, SugarCRM is cloud-based and combines sales,
marketing, customer service and reporting features. While the free
community edition include basic functionality, in order to use the more
advanced features, you'll need to pay for a subscription to the
professional or enterprise edition. Operating System: Windows, Linux, OS
X.
Open Source Tools: Database
11
Firebird
Replaces:
Microsoft
SQL Server, others
It's not as well-known as MySQL (see below), but Firebird also
provides an alternative to commercial closed-source RBDMSs. First
developed in 1981, it offers a mature, stable code base, but doesn't
have corporate backing like MySQL. Operating System: Windows,
Linux/Unix, OS X, Solaris.
12
Kexi
Replaces:
Microsoft
Access
Making no secret of it's intended competition, Kexi's Web site
boldly proclaims it "Microsoft Access for Linux." In fact, Kexi offers
all of the same features and functionality as Access, and it's also
available for Windows and OS X, as well as Linux. Operating System:
Windows, Linux, OS X.
13
MySQL
Replaces:
Microsoft
SQL Server, others
Downloaded or distributed more than 100 million times, MySQL (now
owned by Oracle) is the most popular open source database software in
the world. It's used by a number of well-known companies, including
Yahoo!, Alcatel-Lucent, Google, Nokia, YouTube, and Zappos.com.
Operating System: Windows, Linux, Unix, OS X
Open Source Tools: Desktop Publishing
14
Scribus
Replaces:
InDesign,
QuarkXPress,
Microsoft
Office Publisher
While most desktop publishing programs cost a lot of money,
Scribus offers professional layout features like CMYK color separations,
Spot Colors, ICC color management, and PDF creation—all for free.
However, because of the complexity involved in desktop publishing,
Scribus cannot open or edit files created with similar programs.
Operating System: Windows, Linux, OS X.
Open Source Tools: E-mail/Collaboration/Groupware
15
Collabtive
Replaces:
Basecamp
This cloud-based Web app includes project management, instant
messaging, file and document management, timetracking, and reporting. It
also imports Basecamp files, and if you don't want to host it yourself,
you can purchase hosting and other services from Collabtive. Operating
System: OS Independent.
16
Evolution
Replaces:
Microsoft
Office Outlook
Often called "the Outlook of Linux," Evolution combines e-mail,
calendar, and addressbook capabilities. However, this app only works
with the Linux Gnome desktop. Operating System: Linux.
17
Group-Office
Replaces:
Microsoft
Office Outlook
Group-Office includes a calendar, file sharing, basic CRM
capabilities, e-mail, project management, and some billing features. In

phpGroupWare
Replaces:
Microsoft
Office Outlook,

e-mail, shared calendar, contact management, Web content management,
document management, and project management. It scales for small groups
and large enterprises. Operating System: Windows, Linux.
19
Thunderbird
Replaces:
Microsoft
Office Outlook
The Thunderbird e-mail client boasts tabbed browsing and easy
search—much like the Firefox browser also made by Mozilla. Unlike
Outlook, this app only includes e-mail capabilities, but if you want to
add calendar functionality, you can add Mozilla's
Lightning/Sunbird.
Operating System: Windows, Linux, OS X.
20
Zimbra
Replaces:
Microsoft
Exchange
Zimbra messaging and collaboration suite comes in desktop,
server, and hosted Web client versions. It includes e-mail, contact
management, shared calendaring, and voice communications capabilities.
Operating System: Linux
Resource Planning (ERP)
21
Open ERP
Replaces:
SAP
With its modular design, Open ERP makes it easy to add just the
functionality your company needs. The Web site also includes
comparisons
with other open-source ERP solutions, as well as SAP and Microsoft
Dynamics. Operating System: Windows, Linux.
22
Openbravo
Replaces:
SAP
Web-based, Openbravo offers ERP functionality with a minimal
upfront investment. While the community version source code is available
for download, most enterprises purchase Openbravo as a hosted app from
one of the Openbravo vendors. Operating System: OS Independent
23
ADempiere
Replaces:
SAP
With a very active community and developer group, ADempiere
boasts more than the usual amount of documentation and resources for an
open source project. However, it doesn't have quite as many features and
isn't quite as polished as some of the other ERP solutions. Operating
System: Windows, Linux, OS X, others.
Open Source Tools: File Transfer
24
FileZilla
Replaces:
CuteFTP,
FTP Commander
FileZilla allows users to send large files via regular FTP and
the more secure FTPS and SFTP protocols. While the client version works
with all operating systems, the server version only works on Windows.
Operating System: Windows, Linux, OS X.
25
FireFTP
Replaces:
CuteFTP,
FTP Commander
Downloaded more than 13 million times, FireFTP is a Firefox
add-on that turns your browser into an FTP client. Like WinSCP (below),
it only includes a client, no server software. Operating System:
Windows, Linux, OS X.
26
WinSCP
Replaces:
CuteFTP,
FTP Commander
For Windows only, WinSCP is an file transfer client only—that is,
it allows you to download files securely, but does not allow you to set
up your own FTP server. It supports FTP, SFTP, and SCP. Operating
System: Windows.
Open Source Tools: Financial Management
27
Buddi
Replaces:
Quicken,
Microsoft Money
Extremely simple, Buddi lacks many of the fancy features you'll
find in commercial financial software. However, it's easy to use and
lets you set up accounts and budgets, enter transactions, and run
reports. Operating System: OS Independent
28
Money
Manager Ex
Replaces:
Quicken,
Microsoft Money
Although slightly more robust than Buddi, Money Manager still
lacks the more attractive interface you'll find in Quicken or Money.
However, it does offer the unique feature of allowing you to download
the software to your PC and then access it via the Web on your phone or
another PC. Operating System: Windows, Linux, OS X.
29
TurboCASH
Replaces:
QuickBooks
TurboCash invites small business owners to compare it to
commercial accounting packages with a handy checklist that compares
features. While it doesn't have some of the features you'll find in
QuickBooks, like check printing and multi-currency capabilities, it
offers some features its more well-known competitor doesn't have, like
XML support and remote access. Operating System: Windows.
Open Source Tools: Games
30
FlightGear
Replaces:
Microsoft
Flight Simulator X
With realistic worldwide terrain, more than 20,000 real airports,
and lots of aircraft to choose from, FlightGear provides real
competition to Microsoft's Flight Simulator, and it doesn't require as
many system resources. In fact, it provides such realistic flight
operations that it has been used by universities, aerospace companies,
and the FAA for research. Operating System: Windows, Linux, OS X,
others.
31
FreeCol
Replaces:
Civilization
FreeCol doesn't have the intense graphics of the newest versions
of Civilization, but then again it doesn't require as much memory or CPU
either. It offers a similar style of game play and a similar storyline
as the popular series. Operating System: Windows, Linux, OS X.
32
Frets on Fire
Replaces:
Guitar Hero
Frets on Fire is so much like Guitar Hero that you can even
import Guitar Hero songs. While you can use a guitar controller if you
have one, you can also play the game with your keyboard. Operating
System: Windows, Linux, OS X.
33
Secret Maryo Chronicles
Replaces: Mario Bros. Games
If you've played any Mario Brothers game (and you know you have),
you'll find this game very familiar. It has the sort of 2D graphics you
might remember from a couple of decades ago, and you progress from
level to level by running, jumping, collecting coins, etc. Operating
System: Windows, Linux.
34
StepMania
Replaces: Dance Dance Revolution
StepMania works a lot like Dance Dance Revolution. If you have
dance pads, you can use them (or buy them from the site); otherwise, you
use your fingers to tap the keyboard in rhythm to the music. Operating
System: Windows, Linux, OS X.
Open Source Tools: Gateway Security Appliances
35
Endian Firewall
Community
Replaces:
Check Point Security
Gateways,
McAfee,
SonicWall, others
Like the closed-source Unified Threat Management (UTM) appliances
on the market, Endian combines anti-virus, anti-spam, firewall,
intrusion detection, and other security functions into a single package.
You can download the free community software to turn an old PC into a
Linux-based appliance, or you can buy an appliance right from Endian.
Operating System: Linux.
36
Untangle
Replaces:
Check Point Security
Gateways,
McAfee,
SonicWall, others
Similar to Endian, Untangle combines a whole bunch of open-source
apps for anti-virus, anti-spam, Web filetering, etc. With Untangle, you
have three deployment options: as a router/UTM appliance on a separate
PC, as a transparent bridge (if you already have a firewall/router), or
as a software solution that runs in the background on any Windows PC
connected to your network. Operating System: Windows, Linux.
Open Source Tools: Graphics/Drawing
37
Archimedes
Replaces:
AutoCAD
Like AutoCAD, Archimedes creates 2D and 3D design renderings, but
Archimedes was designed primarily for architects. Thus, it's not as
good for mechanical engineering, but does offer architects some benefits
over AutoCAD. Operating System: Windows, Linux, OS X, others.
38
Dia
Replaces:
Visio
Dia creates diagrams—for flowcharts, org charts, and more. It
doesn't have as many options for art work and styles of boxes as Visio,
but it's good enough for most casual users. Operating System: Windows,
Linux/Unix.
39
Gimp
Replaces:
Photoshop
Gimp makes it easy to edit photos and other images—just like you
would with Photoshop. Suitable for professionals, it includes features
like layers, gradients, photo enhancement, color manipulation, digital
retouching, and much more. For the Windows installer, see
Gimp-win. Operating System:
Windows, Linux
40
Inkscape
Replaces:
Illustrator,
CorelDraw
A vector drawing program, Inkscape offers professional-quality
features (markers, clones, alpha blending, etc.) for graphic designers.
The site now also features an open clip art gallery that you can use in
your drawings. Operating System: Windows, Linux, OS X.
41
Paint.Net
Replaces:
Photoshop
While not quite as powerful as Photoshop and The Gimp, PaintNet
offers many, many more capabilities than the Microsoft Paint utility it
was originally intended to replace. It boasts an intuitive interface,
layering capability, and many special effects. Operating System: Windows
Open Source Tools: Instant Messaging
42
Adium
Replaces:
AIM,
Yahoo! Messenger,
Windows Live Messenger
One of the best reasons to use an open-source IM client is that
it lets you talk with friends on lots of different networks at once.
Adium lets you connect with AIM, MSN, Jabber, Yahoo, and others from
your Mac. Operating System: OS X
43
aMSN
Replaces:
Windows Live
Messenger
This chat client works almost exactly like MSN Messenger (now
known as Windows Live Messenger). Key features include offline
messaging, custom emoticons, multi-language support, webcam support,
tabbed windows, and more. Operating System: Windows, Linux, OS X
44
Pidgin
Replaces:
AIM,
Yahoo! Messenger,
Windows Live Messenger
One of the most popular open-source IM clients, Pidgin connects
with 17 different chat networks. While the basic download doesn't offer
some of the capabilities that the closed source IM clients have (for
example, support for Facebook and Twitter), its large collection of
plug-ins fills in most of the missing features. Operating System:
Windows, Linux/Unix, OS X.
Open Source Tools: Mapping
45
WorldWind
Replaces:
desktop version for
Windows only. Operating System: OS Independent
Open Source Tools: Office Productivity
46
AbiWord
Replaces:
Microsoft
Word
The AbiWord word processor offers most of the features you use
every day in Microsoft Word, and the interface looks a lot like the
older versions of Word. It even opens and saves files in Word and
WordPerfect formats. While it lacks some of the more sophisticated
features, that means you can run it on an older system, and many of the
more advanced features can be added as plug-ins if you really need them.
Operating System: Windows, Linux, OS X, others.
47
FreeMind
Replaces:
MindJet
Both of these mind mapping programs let you create unique
diagrams showing the relationship between ideas—kind of like you would
with a white board during a brainstorming session. The biggest
difference between the two is that the commercial program offers some
online collaboration and Sharepoint integration capabilities that aren't
available in the open-source version. On the other hand, FreeMind
claims to offer faster performance than MindJet. Operating System: OS
Independent.
48
Gnumeric
Replaces:
Microsoft
Excel
This spreadsheet app boasts that it includes all of the functions
in Microsoft Excel, plus 154 others. It imports files from Excel,
Lotus, QuattroPro, and other programs, and it can export to Excel, XML,
PDF, and several other formats. Operating System: Windows, Linux.
49
KOffice
Replaces:
Microsoft
Office
Although it's not as popular as OpenOffice.org, this office
productivity suite from KDE also offers a viable alternative to
Microsoft Office. It includes a word processor/desktop publisher,
spreadsheet, presentation, database, project planner, flowchart, vector
drawing, and a photo editing app. Operating System: Windows, Linux.
50
NeoOffice
Replaces:
Microsoft
Office
NeoOffice is a variation of OpenOffice.org (see below) that's
tailored for the Mac. While OpenOffice.org does work on OS X, NeoOffice
menus and features look and feel more like typical Mac software.
Operating System: OS X.
51
OpenOffice.org
Replaces:
Microsoft
Office
One of the best applications for people who have never used
open-source before, OpenOffice.org includes a word processor,
spreadsheet, presentation creator, and database that read and create
Microsoft-compatible files. Unlike Office, it also comes with a drawing
program and a mathematical equation creator, and of course, it's free.
Operating System: Windows, Linux, OS X, others.
52
StarOffice
Replaces:
Microsoft
Office
For users who would like to try an open-source productivity suite
but who don't want to go without support, StarOffice offers exactly the
same programs as OpenOffice.org with paid support from Oracle. Prices
start at $49.95, with discounts available for volume purchasers.
Operating System: Windows, Linux, OS X, others.
Open Source Tools: Operating System
53
Red Hat
Replaces:
Windows
Calling itself "the world's leading open source application
platform," Red Hat offers both desktop and server versions of Linux that
are designed primarily for enterprise users. One-year subscriptions
which include basic support start at $349 for the server version and $80
for the desktop version, or you can get a free, non-supported version
that is nearly identical from
Fedora.
54
SUSE
Replaces:
Windows
Novell also targets large business users with it's SUSE version
of Linux. Prices start at $349 for the server version and $50 for the
desktop version, and free versions are available from
openSUSE.
55
Ubuntu
Replaces:
Windows
Because it is so user friendly, Ubuntu is one of the most popular
versions of Linux for home users, particularly netbook users. Unlike
Windows, Ubuntu (and the other versions of Linux) includes most of the
applications you'll need, so you don't have to purchase separate
software for word processing, spreadsheets, e-mail, video, music, etc.
Open Source Tools: Password Manager
56
KeePass
Replaces:
RoboForm,
LastPass
Like the other password managers, KeePass stores your passwords
in an encrypted database, so that you only have to remember one master
password. Its Web site claims that its encryption is so strong that
"even if you would use all computers in the world to attack one
database, decrypting it would take longer than the age of the universe."
However, KeePass does not automatically fill in Web forms for you like
the commercial products do. Operating System: Windows.
Open Source Tools: PDF Tools
57
PDFCreator
Replaces:
Adobe Acrobat
With this tool, you can create a PDF file from any application
that can print. It also includes digital signature and encryption
capabilities, but it lacks some of Acrobat's form creating capabilities.
Operating System: Windows.
58
Sumatra
PDF
Replaces:
Adobe Reader
You don't have to use Adobe Reader to open PDF files. Sumatra
also lets you view PDFs, and it's extremely lightweight, so it loads and
operates much faster. Operating System: Windows.
Open Source Tools: Project Management
59
OpenProj
Replaces:
Microsoft
Project
Downloaded more than 1.2 million times, OpenProj provides nearly
identical project management capabilities as Microsoft Project and even
opens Microsoft Project and Primavera files. It's also available in a
cloud-based version called "Projects On Demand" for $20 per month per
user. Operating System: Windows, Linux, Unix, OS X.
60
GanttProject
Replaces:
Microsoft
Project
Like OpenProj, GanttProject opens Microsoft Project files and
offers much of the same functionality. However, it's not quite as
polished as either OpenProj or Microsoft Project. Operating System:
Windows, Linux, OS X.
Open Source Tools: School Management
61
Moodle
Replaces:
Blackboard
Both of these course management systems make it easy for
instructors to conduct online courses, but Moodle offers the distinct
advantage of being available for free. It's currently used on nearly
50,000 sites in more than 200 countries. Operating System: Windows,
Linux, OS X.
62
openSIS
Replaces:
PowerSchool
Some school districts claim to have lowered their TCO by 75
percent or more when switching from PowerSchool to openSIS. It includes
modules for student demographics, attendance, gradebooks, scheduling,
report cards, and more. Operating System: Windows (Linux coming soon).
Open Source Tools: Text Editor
63
jEdit
Replaces:
WordPad
This Java-based replacement for the standard Windows text editor
includes a number of helpful features for developers. For example, it
indents automatically and highlights syntax for 130 different
programming languages, and it has convenient keyboard shortcuts for many
functions. Operating System: OS Independent
Open Source Tools: Utilities
64
Launchy
Replaces: Windows Start Menu
Instead of hunting through your Windows start menu or file
manager, just type a couple of letters and Launchy will find the
application or file you're looking for. It's fast and very easy to use.
Operating System: Windows, Linux, OS X
65
DocFetcher
Replaces: Standard desktop search
If you're looking for text in a document, DocFetcher can find it
quickly. It doesn't search application and system files, but it does
find text within documents very quickly. Operating System: Windows,
Linux
66
UltraDefrag
Replaces: Disk Defragmenter
This utility offers a couple of benefits over the Windows Disk
Defragmenter. Most notably, it offers better speed, lets you schedule
your defrag, and can automatically turn off your system when it's done.
Operating System: Windows
67
Karsten SlideShow
Replaces: My Pictures Slideshow
This screensaver works like the "My Pictures Slideshow" in
Windows, except that it lets you decide which pictures should be used.
It can also play video clips or run a slideshow as your desktop
wallpaper. Operating System: Windows
Open Source Tools: Video Tools
68
Avidemux
Replaces:
Adobe
Premiere
Although it doesn't have nearly the wealth of features available
with Adobe Premiere, Avidemux performs simple video cutting, filtering,
and encoding tasks well. It also includes some scripting and job queue
capabilities so that you can automate some repetitive tasks. Operating
System: Windows, Linux, OS X, others.
69
VLC Media Player
Replaces:
Windows
Media Player
This meida player supports most audio and video file formats, and
it can play from files, physical media (DVDs, CDs, etc.), TV cards, and
streaming media. It can also convert files from one format to another
and act as a streaming server—all without the need for external codecs.
Operating System: Windows, Linux, OS X, others.
70
XBMC Media Center
Replaces:
Windows
Media Player
Winner of numerous awards, XBMC plays nearly all types of audio
and video files—and looks great doing it. Designed to work with home
theater PCs (HTPCs), it supports most remote controls, and it
automatically creates a personal library, including cover art, for all
of your audio and video files. Operating System: Windows, Linux, OS X.
Open Source Tools: VoIP
71
QuteCom
Replaces:
Skype
Formerly known as "WengoPhone," QuteCom offers free calling to
other SIP-based VoIP software users, and if you have a SIP service
provider, you can also call landlines, mobile phones, etc.
Unfortunately, documentation for QuteCom is scarce, so if you want ease
of use, Skype may offer a better option. However, if you want to be able
to choose your own service provider, the open-source software is the
way to go. Operating System: Windows, Linux, OS X.
Open Source Tools: Web Site Creation
72
Bluefish
Replaces:
Adobe
Dreamweaver,
Microsoft
Expression Web
While it's not quite as user-friendly as its commercial
competitors or the other open-source options listed here, Bluefish
offers a very fast WYSIWYG HTML editor that doesn't use a lot of system
resources. Aimed at coders more than designers, it also includes support
for a number of other programming languages. Operating System: Windows,
Linux, OS X, others.
73
NVU
Replaces:
Adobe
Dreamweaver,
Microsoft
Expression Web
NVU claims to be "the number one free Web authoring system."
While it's definitely aimed more at novices than professionals, it
inlcudes many of the same features as the commercial HTML tools, and
the Web site also helps newbies register a domain name and find hosting
for their sites. Operating System: Windows, Linux, OS X, others.
74
SeaMonkey
Replaces:
Adobe
Dreamweaver,
Microsoft
Expression Web
Loosely supported by Mozilla, SeaMonkey includes a Web browser,
feedreader, e-mail client, and IRC chat client, as well as an HTML
authoring tool. Unlike the commercial tools, SeaMonkey doesn't offer an
easy way to convert graphic files to Web pages, but it does include some
advanced CSS capabilities and a built-in Java de-bugger. Operating
System: Windows, Linux.
75
XML Copy Editor
Replaces:
XMLSpy
If you're looking for a basic XML editor with maximum speed, give
XML Copy Editor a try. However, if you need a more full-featured
solution or integration with SharePoint, Visual Studio, or Eclipse, the
commercial software offers a better option. Operating System: Windows,
Linux.
