# romm vs hindsight

romm and hindsight share 12 technologies: FastAPI, Postgres, AIOHTTP, uvicorn, SQLAlchemy, alembic, cryptography, pillow, Pydantic, OpenTelemetry, opentelemetry-instrumentation-fastapi, and PostCSS. Both are written in Python.

| Size | 467,510 lines written, 1,077 code files | 749,226 lines written, 1,156 code files |
| Who writes it | 24.4% of its commits signed by AI. With Claude Code, GitHub Copilot, Gemini CLI, Amp, and Cursor | 6.8% of its commits signed by AI. With Claude Code, Cursor, Codex, and GitHub Copilot |
| Activity | Last push November 9, 2026, 10,677 commits, 14,276 stars | Last push November 5, 2026, 4,037 commits, 58,979 stars |
| Tests | 739 test files. 62.1% of its code files have a test that imports them | 1,333 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.
