| Install complexity | EASY | Easy with a supported package manager; Homebrew must already be installed for this command. Official binaries, Windows, Linux, and source options are documented. | Easy — npm, Bun, Homebrew, or Nix |

| 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 using coding agents and wanting to review the specification and plan before code. It keeps tasks, acceptance criteria, and decisions inside the project and exposes them through CLI, a local browser, or MCP. It is not a replacement for a centralized enterprise SaaS board with organization-wide permissions and reporting. |
