olud.ai is an independent, founder-run directory of open-source artificial intelligence. Its mission is simple: for every closed, paid AI product, help you find the open, private, self-hostable option — and give you honest data to choose with.
Open-source AI moves incredibly fast — models, tools and frameworks appear weekly — but the information about it is scattered across thousands of repositories, changelogs and pricing pages. Most directories are either abandoned, pay-to-play, or stop at a name and a link. This site was built to be the opposite: automatically fresh, structured enough to compare, and free of sponsored rankings.
100+ hand-checked open-source AI tools with structured facts: license, local execution, language, ease of use and what each is genuinely best at.
10,000+ open-source AI projects tracked through the GitHub API, with star velocity to surface what's rising — refreshed daily.
Hundreds of head-to-head tool comparisons, plus live model pricing and context data refreshed hourly, with price history.
Guides to replace popular closed AI products — ChatGPT, Claude, Gemini, Midjourney, GitHub Copilot, Perplexity and more — with open-source equivalents.
Everything is available in six languages (English, French, German, Spanish, Italian, Portuguese), with English as the editorial source of truth.

Data sources, selection criteria, comparison rules and update frequency — all documented, nothing hidden.
