# composio vs hindsight

composio and hindsight share 11 technologies: OpenAI, Zod, ag2, openai-agents, CrewAI, google-adk, autogen-core, LangChain, Pydantic, eve, and ai. composio is written in TypeScript and hindsight in Python.

- [ComposioHQ/composio](https://seerepo.com/r/ComposioHQ/composio): Composio powers 1000+ toolkits, tool search, context management, authentication, and a sandboxed workbench to help you build AI agents that turn intent into action.

## Side by side

| | composio | hindsight |
|---|---|---|
| Size | 384,701 lines written, 895 code files | 775,545 lines written, 1,263 code files |
| Who writes it | 31.4% of its commits signed by AI. With Claude Code, Devin, Cursor, GitHub Copilot, and Codex | 6.8% of its commits signed by AI. With Claude Code, Cursor, Codex, and GitHub Copilot |
| Activity | Last push November 7, 2026, 4,791 commits, 30,965 stars | Last push November 12, 2026, 4,120 commits, 60,699 stars |
| Tests | 669 test files. 43.6% of its code files have a test that imports them | 1,381 test files. 28.2% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
