About
DrawCMS is an open-source, self-hostable animated diagram editor that a compatible AI agent can use to read a codebase and generate an editable diagram, then walk through the flow step by step on the canvas. It supports architecture, sequence, and network diagrams with infrastructure icons, and diagrams can also be drawn or edited manually, helping developers keep track of how AI-written code actually works after they've moved on.
At a glance
DrawCMS is a canvas for diagrams that show how a system moves through a sequence. It is worth trying if a static diagram makes it hard to see which service acts first or how a request travels.
Good fit
Developers explaining a workflow, architecture or request sequence to someone else.
Consider something else when
Skip it if a static sketch already tells the story or you need the diagram to update automatically when the code changes.
Start here
Read the sequence example, then sketch a three-step request with synthetic service names. Play it back and check whether a reader can identify the order without a separate explanation.
Cost and requirements
The repository lists AGPL-3.0-only licensing and describes a local-first canvas without an account. Agent-assisted editing needs a compatible client and the editor’s tool connection.
Limits to know
The diagram represents the flow you describe. Verify generated steps against the implementation. A connected model can receive details you provide about your system.

Why it made the leaderboard
DrawCMS lets you point a coding agent at your repo and get back a walkable, editable diagram of how a request actually flows through the system, useful when agent-generated code outpaces anyone's mental model of it.
