# multica vs hindsight

multica and hindsight share 4 technologies: Next.js, React, Postgres, and OpenAI. multica is written in Go and hindsight in Python.

- [multica-ai/multica](https://seerepo.com/r/multica-ai/multica): Make humans and AI agents work as one team — open-source and self-hostable.
- [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, Postgres, OpenAI
- Only in multica: Expo, chi, net/http, Redis, PostHog, Resend
- Only in hindsight: FastAPI, Claude

## Side by side

| | multica | hindsight |
|---|---|---|
| Size | 1,347,852 lines written, 2,534 code files | 746,685 lines written, 1,184 code files |
| Who writes it | 35.6% of its commits signed by AI. With Claude Code, Codex, Cursor, and GitHub Copilot | 6.9% of its commits signed by AI. With Claude Code, Cursor, Codex, and GitHub Copilot |
| Activity | Last push October 28, 2026, 5,228 commits, 54,065 stars | Last push October 28, 2026, 3,952 commits, 54,541 stars |
| Tests | 2,243 test files. 62.6% of its code files have a test that imports them | 1,315 test files. 30.7% 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.
