• Real-time multi-user drawing with multi-cursor display
• Auto-generated memorable passwords (e.g., 'blue-otter-42-moon')
• Per-user undo / redo (Cmd+Z, Cmd+Shift+Z)
• Pan and zoom (10%-500%)

How it works

1. Open freedrawboard.app and click 'Create Board'
2. Get an auto-generated strong password — share it with anyone you want to draw with
3. They join by entering the password — no signup for them either
4. Draw, type, drop images. Everything syncs in real time. Drawings never touch a database.

Common use cases

• Quick design feedback sessions
• Classroom diagramming with students
• Pair brainstorming for product ideas
• Casual sketches with remote teammates
• Throwaway whiteboarding without setting up a shared account

How it compares

Compared to Miro and Mural — those are heavyweight enterprise tools with persistent boards, infinite features, and account requirements. Freedrawboard is instant: no signup, password-protected rooms. For ongoing team workspaces use Miro; for quick collaborative sketches use freedrawboard. Compared to Excalidraw, freedrawboard's real-time sync works without an Excalidraw+ subscription. Compared to Google Jamboard (discontinued in 2024), freedrawboard fills the no-account quick-collab gap.

Privacy

Drawings are relayed through Supabase Realtime but never stored on any database. The password is the room identity — without it, the URL leads to a different empty channel. Local board copies live in your browser and persist across refreshes; export to PNG to keep a permanent copy.
