Open-source alternatives to paid AI tools

Looking to replace a paid AI subscription with something free you can run yourself? Pick the tool you use now. Each page lists the open-source and local options we verified, with their licenses and the trade-offs.

Alternatives are listed only where we could verify the license on the project's own page or repository. “Open source” means the code is public under the license shown; “open weights” means the model files can be downloaded; “source-available” means the code can be read but the license is not open source. Quality is not benchmarked here. See all open-source and local AI tools.
