# neon vs zed

neon and zed share 11 technologies: axum, tower, aws-sdk-s3, Postgres, AWS S3, Tokio, jsonwebtoken, tracing, tracing-subscriber, env_logger, and log. Both are written in Rust.

- [neondatabase/neon](https://seerepo.com/r/neondatabase/neon): Neon: Serverless Postgres. We separated storage and compute to offer autoscaling, code-like database branching, and scale to zero.
- [zed-industries/zed](https://seerepo.com/r/zed-industries/zed): Code at the speed of thought – Zed is a high-performance, multiplayer code editor from the creators of Atom and Tree-sitter.

- 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.
