Dosu
AI maintainer for open-source repos — triage, Q&A, docs, and stale-issue hygiene.
About
Dosu (dosu.dev) is an AI assistant built for open-source maintainers, founded by Devin Stein. Installed on 10,000+ GitHub repositories (including LangChain, Airflow, and Dify), it answers user questions from codebase context, auto-labels and triages issues, detects duplicates, and manages stale issues. Free for public repositories.
Dosu has evolved beyond triage into "knowledge infrastructure for agents and humans": self-documenting PRs that propose doc updates when code changes, an MCP server giving coding agents shared project memory, and dosu-skill installable via npx for AI coding agents. Its grounding mechanism indexes the actual repo/issues/docs to avoid hallucination — the original capability everything else builds on.
What it can do
- Automated issue triage and auto-labeling
- 24/7 Q&A grounded in repo context
- Stale-issue detection and resolution
- Self-documenting PRs (doc-drift detection)
