Compare the best free and open-source alternatives to Devin — 7 verified projects with explicit catalog relationships. Inspect licenses, GitHub activity, self-hosting signals, and migration fit before you switch.
Official product reference Devin↗Only explicit alternative relationships are shown—never inferred competitor claims.
This guide compares 7 verified open-source alternatives to Devin, including OpenCode, Zed, OpenHands, and Cline.
Projects appear across Infrastructure, Content & Collaboration, and AI & Machine Learning. 2 options include a self-hosting signal — see the self-hosted catalog. Ranking follows public GitHub stars and recorded momentum—not vendor marketing. Compare projects side by side, then confirm license fit, migration effort, and operational ownership before adopting any option.
Engineers searching open-source Devin alternatives, autonomous coding agents, and self-hosted AI software engineers.
Migration tip: Pilot one real ticket in a sandbox with tests required before merge. Start with OpenHands for autonomy experiments or Cline/Aider for daily supervised loops—then add MCP tools gradually.

Map must-have capabilitiesList the workflows in Devin you cannot drop during migration.
Verify the licenseConfirm it fits your use, distribution, and compliance model. Browse license briefs.
Run a proof of conceptTest real data, integrations, clients, and failure modes. Use Compare for side-by-side checks.
Plan ownershipAssess upgrades, backups, support, and an exit path. Read when self-hosting is worth it.
OpenHands is the closest open cousin for longer autonomous tasks. Cline, Goose, Aider, and Codex CLI cover interactive or terminal engineering loops with more oversight.
Yes for several FOSS agents. You own sandboxes, model routing, secrets policy, and review gates—autonomy without ops is not free.
Devin markets autonomous engineering. Claude Code/Codex are agent/CLI oriented. Cursor/Windsurf are AI editor suites. Match autonomy needs before comparing brands.
Only with allowlisted tools, no prod secrets by default, mandatory tests, and human merge review. Log tool calls.
Narrow the same alternatives by search, license, tags, or self-hosting signals when you need a tighter shortlist.
