# OpenSourceAI.tech

> An independent, founder-run directory and data platform for open-source AI: 100+ hand-curated tools, 1,500+ GitHub projects tracked daily, live model pricing refreshed hourly, head-to-head comparisons, and open-source alternatives to popular AI products. Available in English, French, German, Spanish, Italian and Portuguese (English is the editorial source of truth).

All numbers come from public, verifiable sources (GitHub API, OpenRouter API) and are collected automatically. Listings and rankings cannot be bought. Data collection and selection criteria are documented on the methodology page.
