Why move beyond Draw.io?

Faster docs, fewer files

Draw.io is great for one-off diagrams, but it creates a manual, file-based workflow that slows teams down. Every change requires a new export, every review requires a new upload, and every update requires a new layout. Mermaid keeps diagrams in your codebase, so they stay version controlled, auto-layout, and instantly shareable. That means faster documentation, fewer file conflicts, and a developer-friendly workflow that keeps your team moving.
