# cognee vs hindsight

cognee and hindsight share 4 technologies: Next.js, React, FastAPI, and OpenAI. Both are written in Python.

- [topoteretes/cognee](https://seerepo.com/r/topoteretes/cognee): Cognee is the open-source AI memory platform for agents. Give your AI agents persistent long-term memory with small models for free
- [vectorize-io/hindsight](https://seerepo.com/r/vectorize-io/hindsight): Hindsight: Agent Memory That Learns

## What they share and what sets them apart

- In common: Next.js, React, FastAPI, OpenAI
- Only in cognee: None
- Only in hindsight: Postgres, Claude

## Side by side

| | cognee | hindsight |
|---|---|---|
| Size | 653,245 lines written, 2,198 code files | 744,037 lines written, 1,156 code files |
| Who writes it | 17.2% of its commits signed by AI. With Claude Code, CodeRabbit, Cursor, GitHub Copilot, and OpenHands | 6.9% of its commits signed by AI. With Claude Code, Cursor, Codex, and GitHub Copilot |
| Activity | Last push November 1, 2026, 8,651 commits, 32,980 stars | Last push October 30, 2026, 3,977 commits, 56,348 stars |
| Tests | 1,483 test files. 11.1% of its code files have a test that imports them | 1,319 test files. 30.2% 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.
