The Everything-on-Your-Branch Architecture

Short summary

Neon's platform preview extends database branching to fork the entire application stack — Postgres, object storage, serverless functions, and AI gateway config — simultaneously at a point in time. The author tested a full-stack AI image-agent project and verified each layer was isolated: separate storage endpoints, independent function URLs, and per-branch gateway config. Copy-on-write storage and scale-to-zero compute keep idle branches near-free, making one-per-PR practical.

• •Neon branches now fork DB, object storage, functions, and AI gateway together
• •Author verified full-stack isolation with a real AI image-agent project
• •Copy-on-write and scale-to-zero make per-PR branches cost-effective
