Docs that never go stale

API and architecture docs that are always current.

nostackai generates your documentation from your configuration every time you open it. Nothing is pre-rendered or cached, so the docs match what is running.

API reference

A live OpenAPI 3.1 spec, for every endpoint.

Every entity, Logic Block and public endpoint, with fields and descriptions. Download it for Swagger, Postman or code generators.

  • Generated from the current config
  • Filter by endpoint, expand any operation
  • The same reference is served to AI clients over MCP

App Flows

How the app works, step by step.

Built-in flows for sign-up, sign-in, invitations and workspaces, plus flows you write yourself. Each step names who acts, which asset is involved and which AWS resource runs it.

  • Request walkthroughs on the infrastructure diagram
  • They flag themselves "may be out of date" when something they pass through changes
