| Best use | Ideal for a solo developer or small team that wants API collections and tests beside the code with Git review. Use it for repeatable REST, GraphQL, gRPC, and WebSocket checks—not live cloud collaboration or load testing. | For a Python developer or small team that wants a shared setup rather than relying on manually installed packages. Commit the dependency definition and lockfile, then sync the environment and run commands with uv. It does not isolate the operating system or untrusted code, or replace application compatibility tests. | For developers and small teams that want architecture and data-flow diagrams close to the repository and reviewable as text. Use it when relationships matter more than pixel-perfect placement; not for free-form marketing design or exact manual positioning. |
