OpenFlowKit

Free, open-source local-first AI diagramming for architecture and flowcharts

Webfreeglobal

A free, open-source local-first web app for creating and refining architecture and flow diagrams from templates, code, structured imports, or AI prompts, with the option to export animated MP4 walkthroughs. It is aimed at developers and technical writers who need to generate and iterate system diagrams locally rather than relying on paid diagramming services, and can be driven from first-party MCP servers to connect with AI assistants.
