AI tools with public source code, self-hostable models, and open licenses — for developers who want transparency, control, or customization.
This page lists AI tools whose source code is publicly available, typically under an open-source license, and often self-hostable. Open-source tools matter when you need full control over your data, want to audit how a model or pipeline works, or need to customize behavior beyond what a hosted product allows. For each listing, we describe what the tool does, its license, where the code lives, and what self-hosting realistically requires — because "open source" can mean anything from a permissive license with active maintenance to an abandoned repo. If you are evaluating tools for a production environment where transparency and ownership matter, the listings below are a practical starting point.
No open-source tools are listed yet. We add them as we verify the license and activity of each repository — browse the full directory in the meantime.
