# dify vs skypilot

dify and skypilot share 4 technologies: psycopg2-binary, Postgres, boto3, and Tailwind CSS. Both are written in Python.

- [langgenius/dify](https://seerepo.com/r/langgenius/dify): Build Agentic workflows, RAG pipelines, with rich AI model and tool support on one collaborative workspace. Deploy on cloud, VPC, or self-hosted, so teams move from prototype to production without rebuilding the stack.
- [skypilot-org/skypilot](https://seerepo.com/r/skypilot-org/skypilot): The AI Compute Platform for frontier teams. SkyPilot turns fragmented AI compute into one AI supercomputer, so frontier AI teams build custom intelligence faster.

- 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.
