GravelGraph is a free, no-login, browser-based diagramming tool for solution architects and
engineers. Draw a system from a catalog of cloud and infrastructure components — with official
AWS, GCP, Azure and Cloudflare icons — then press play to watch live data animate through it,
ideal for pitches, demos and documentation. Everything runs in your browser: diagrams are
self-contained .gravel files and shareable links, with no server, no database and
no sign-up. Import from Mermaid or Terraform; export to PNG, SVG, PDF, animated GIF or video;
present full-screen; and embed live, animated diagrams anywhere. It also works offline as an
installable app.
