- [pathwaycom/pathway](https://seerepo.com/r/pathwaycom/pathway): Python ETL framework for stream processing, real-time analytics, LLM pipelines, and RAG.

## What they share and what sets them apart

- In common: FastAPI, Postgres, MongoDB
- Only in mem0: Supabase, Redis, OpenAI, PostHog, Anthropic, AWS S3
- Only in pathway: None

## Side by side

| | mem0 | pathway |
|---|---|---|
| Size | 234,363 lines written, 636 code files | 350,038 lines written, 610 code files |
| Who writes it | 3.6% of its commits signed by AI. With Claude Code and Cursor | 0% of its commits signed by AI |
| Activity | Last push October 29, 2026, 2,650 commits, 68,064 stars | Last push October 29, 2026, 2,331 commits, 62,042 stars |
| Tests | 324 test files. 46.2% of its code files have a test that imports them | 272 test files. 15.9% 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.
