An infinite canvas for system design. Search every AWS & GCP service, wire them up, and hover any piece to see what it does — or let AI draw it from your codebase.
Share a diagram with a link and your whole team lands on the same canvas — live cursors, names, and selections moving as everyone edits. It stays end-to-end encrypted, too: the share link carries the key in a part of the URL your browser never sends to our servers.
Send one link and teammates join instantly — no exporting, no emailing files back and forth.
Live cursors, avatars, and selection highlights show who's here and exactly what they're working on.
Every move, label, and connection syncs in a fraction of a second, so you never overwrite each other.
Connect the SchemaFlow MCP to Claude Code or Codex, point it at a repo, and it maps the architecture for you — components, connections, and plain-English descriptions — laid out and ready to edit.
Developer preview.
System diagrams are a map of how your product works — sometimes its weak points too. So SchemaFlow encrypts them on your device before they ever reach our servers. We store scrambled ciphertext and nothing else.
Names and contents are encrypted in your browser with a key derived from your passphrase.
Your passphrase and key stay on your device. They're never sent to us, so we can't decrypt your work.
Open the database and all you'd find is scrambled text — not a single component or connection.
