Top open-source AI tools
Tools you can self-host and read the source of, ranked by GitHub stars. Stars are a popularity signal, not a quality one, so our score is shown beside them. Our picks lead the table and are labelled; the score column is never touched. How we score.
There are 174 tools here. 100% have a free tier, and the median score is 7. Open source is the most common pricing model at 98.3%.
