The open-source diagramming studio for builders
Paste a public GitHub repository and OpenFlowKit reads its files in the browser to draw modules and connections, with every arrow cited to the source line it came from.
29 diagram tools for Claude Code, Codex, Cursor, VS Code, Windsurf or any MCP client, so an agent can draw on the diagram you have open, one undo away.
Write or paste Mermaid, D2 or Structurizr; the text and the canvas remain the same diagram, so you can round-trip between syntax and visuals.
Move from system context to containers to components in linked views that all stay grounded in a single architecture model.

Google's AI tool for generating mobile and web UI designs from prompts
Describe an app screen in natural language and Stitch produces multiple complete UI designs, including mobile and web layouts.
Upload a sketch, screenshot or existing screen and Stitch produces a matching design interpretation.
Iterate with follow-up prompts to change layout, color themes and components without starting over.
Move generated designs toward implementation with export options suited to design and development handoff.
Builds full-stack web applications from natural language, moving further into functional app development than standard UI design tools.
#1Produces high-quality frontend code directly from text prompts, but acts more as a developer tool than a pure designer.

Generates editable wireframes and mockups similarly, but offers tighter integration with design systems and Figma.
AI diagrams and technical design docs built from your code and systems

AI diagramming, mind mapping and project tools with 50,000+ templates

Converts sketches and text prompts into wireframes, but focuses more on rapid prototyping than production code generation.
SpecialistDesign-aware AI agent that turns Figma files, URLs, and prompts into live apps
Free / Open-sourceOpen-source AI automation that unifies agents, flows and 770+ app integrations


Builds multi-screen interactive prototypes from PRDs and prompts, though with a stronger emphasis on exportable code.

AI-powered visual collaboration for diagrams, mind maps, and charts
Generates code-ready UI components quickly from prompts, but lacks advanced multi-screen user flow management.
One AI workspace for diagrams, docs, whiteboards and project delivery
