| 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 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. | Best for an individual developer or small team that wants self-hosted website, API, DNS, and certificate checks with a status page and threshold-based alerts. It combines active checks and simple history in one service. It does not replace resource monitoring, logs, or distributed tracing. |
