Excalidraw+
Replaceable in one session with an AI coding agent.
The paid tier of the hand-drawn diagram editor: saved workspaces, sharing with a team and search across your drawings, on top of an editor that is free.
The editor is free. Build the library around it. START FROM THE RIGHT PLACE - Excalidraw is MIT-licensed and embeddable as a React component. Never reimplement the canvas STACK - The Excalidraw component, a small Node server, SQLite, S3-compatible storage SAVING - A drawing is the scene JSON plus a PNG preview generated on save - Store the JSON in object storage and the metadata in SQLite SEARCH - Extract every text element from the scene JSON on save into a searchable column - That single step makes a library of drawings findable, and is the feature people actually miss SHARING - A link is a random token with an expiry and a view-or-edit flag - Never expose the storage key COLLABORATING - Excalidraw ships a collaboration protocol; run its room server rather than writing one Include the save route, the text extraction and the share tokens.
What you lose
- A hosted workspace with search across every drawing, which is what the fee buys
- Live collaboration on the same canvas with presence
- Sharing and permissions for a team, rather than a link anyone can open
If you would rather not build
- tldraw, for a similar canvas with a permissive licence
