Lingarr scores highest at 92/100, with 45 commits in the last 90 days, 875 GitHub stars and its latest release (1.3.0) published 1 months ago. It is also the most active by raw commit count.

Which DeepL alternatives use a permissive licence?

None of the 2 tracked alternatives use a permissive licence; 2 are copyleft (GPL, AGPL or similar), which requires publishing changes to any modified version you distribute.

Which DeepL alternatives run in Docker?

2 of 2 publish a Docker image or Compose file: Lingarr, Libre Translate. Docker support contributes 10 of the 100 available health points, because it is the clearest signal that self-hosting is a supported path rather than an afterthought.
