| Best use | 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. | 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. |
