GitHub repos
The most-starred AI GitHub repositories among developers (October 2026)
OpenCode passes 218,000 stars and leads our ranking of 20 AI repositories for developers; coding agents account for 40% of all stars (GitHub API, October 20, 2026).
AI GitHub repositories
Coding agents, inference engines, open models, agent frameworks, MCP and benchmarks: the public repositories that matter to developers who code with AI, backed by figures.
Selection criteria
- Relevance: the repository falls within OrigoTech's scope (AI for developers: coding agents, editors, open models, inference, agent frameworks, MCP, evaluation).
- Popularity: number of GitHub stars; every listed repository has more than 5,000.
- Activity: at least one push in the last twelve months, and the repository is neither archived nor declared read-only.
Source of figures: GitHub API (stars, forks, declared licence, last push date), checked on .
