The AI hub.
OLUD INDEX—Open-source and commercial AI side by side — projects, models, alternatives, releases and pricing, measured. Rebuilt every day, new releases within the hour.

The ten most-starred AI tools and the ten most-installed share one name
Across the 78 tools where we measure both, star rank and install rank are nearly independent — Spearman 0.131. TensorFlow is first by stars and thirteenth by installs. LangChain is the only name in both top tens.
459 repos hold half the stars in open-source AI
The catalogue holds 10,840 projects and 58,331,228 stars. Half of them sit on 459 repositories — 4.2% of the shelf.
One fork for every 6.9 stars — and what the ratio tells you
A star costs one click; a fork is a copy someone took. Across 10,840 projects the ratio barely moves — which turns its outliers into signal.
127 repos above 10,000 stars are held up by fewer than ten people
Across 1,190 projects above 10,000 stars, the median has 78 contributors, 54.6% have fewer than 100, and 127 have fewer than ten.
Why olud.ai ?
One live hub for the whole AI landscape — open-source and commercial, measured every day and watched hourly for new releases, so you never miss what ships.
Your project already has a page. Take it.
Every open-source AI project we track gets its own page, rebuilt every day and translated into six languages. If you maintain one of them, claiming it takes about a minute: sign in with GitHub and it confirms the repo is yours. No commit to push, no token to store, no write access, no card.
Seven live panels in one screen: GitHub momentum, model price changes, project health, ELO rankings and the latest releases — refreshed continuously.
