Whiteboarding & Diagrams

Why Self-Host Your Whiteboarding and Diagram Tools?

Miro charges $8-16 per user per month, LucidChart starts at $7.95, and Microsoft Visio requires an Office 365 subscription. For teams that use whiteboards and diagrams intermittently — during planning sessions, architecture reviews, or brainstorming — paying per-seat monthly fees for occasional use is wasteful. Self-hosted whiteboarding tools provide the same infinite canvas, real-time collaboration, and diagramming capabilities without recurring per-user costs.

Excalidraw provides a hand-drawn-style whiteboard that is immediately intuitive — shapes look sketched rather than precise, which encourages brainstorming over perfectionism. It supports real-time collaboration, libraries of reusable components, and export to PNG/SVG. Draw.io (diagrams.net) is the most comprehensive diagramming tool, supporting flowcharts, UML, network diagrams, floor plans, and dozens of other diagram types with extensive shape libraries. It can store diagrams directly in your Nextcloud, Git repository, or local storage.

Affine Community Edition combines whiteboarding with document editing in a single tool — think Notion meets Miro, where you can switch between document mode and canvas mode within the same workspace. tldraw provides a minimal, fast whiteboard focused on freeform drawing and simple shapes. Pad.ws offers a collaborative whiteboard with real-time synchronization for quick team sketching sessions. The self-hosting advantage extends beyond cost: your architecture diagrams, system designs, and strategic planning boards often contain proprietary information that should not live on Miro’s servers.
