Here’s a non-exhaustive list of links to existing free/open-source machine translation systems, which I will try to complete as I find about them. To the best of my knowledge, software listed here has:
- either a free license as defined by the Free Software Foundation,
- or an open-source license as defined by the Open Source Initiative.
