Excalidraw
open sourceMITLocal or hosted124kaug 2026Fast multiplayer whiteboards, libraries, links, exports, and workshop-friendly sketching; fewer facilitation widgets, much less account bureaucracy.
The catch vs LucidsparkExcalidraw is faster for sketching but omits many structured facilitation features such as advanced voting, timed activities, and enterprise workshop controls.
Install, platforms & data +
- platforms
- webself-hostedthey host it
- install
- Open the hosted web app/PWA, or deploy the static app and optional collaboration server
- setup
- None for the hosted app; the trade-off appears later because durable workspace organization, centralized team administration, and managed version history are deliberately minimal
- your data
- Solo drawings are stored in browser storage or explicit .excalidraw JSON files; exports include PNG and SVG; multiplayer room data is end-to-end encrypted and the decryption key is carried in the share URL

AFFiNE
open sourceMITLocal or hosted71kaug 2026Collaborative whiteboards tied to docs, databases, and planning views; broader than Lucidspark, more infrastructure if self-hosted.
The catch vs LucidsparkAFFiNE offers a broad workspace but has a smaller facilitation toolkit, template library, timer and voting workflow, and integration ecosystem than Lucidspark.
Install, platforms & data +
- platforms
- desktopwebself-hostedself-host, real ops
- install
- Hosted signup or desktop app; Docker Compose for self-hosting
- setup
- The hosted/desktop app installs cleanly; self-hosting is a multi-service Docker deployment that needs a domain, TLS, secrets, storage, backups, and AI-provider keys for AI features
- engines
- Self-hosted AFFiNE AI can be configured with OpenAI, Anthropic, Google Gemini, and FAL credentials
- your data
- Local-first clients keep workspace data locally and sync to AFFiNE Cloud or the operator's server; self-hosting uses PostgreSQL, Redis, and persistent blob storage

CryptPad
open sourceAGPL-3.0+Local or hosted7.8kjul 2026Persistent encrypted whiteboards inside a shared drive with permissions and team folders; visually plain, operationally serious.
The catch vs LucidsparkIts whiteboard lacks Lucidspark's workshop templates, voting, timers, facilitation controls, breakout workflows, and polished participant experience.
Install, platforms & data +
- platforms
- webself-hostedthey host it
- install
- Use a public CryptPad instance, or self-host the Node.js service behind a reverse proxy
- setup
- Public hosting is immediate; self-hosting requires two domains or subdomains, HTTPS, strict security headers, Node.js configuration, persistent storage, and careful upgrades/backups
- your data
- Documents are encrypted in the browser before upload; the server stores encrypted document files, blobs, and account pin metadata on its filesystem and cannot read document content

WBO
open sourceAGPL-3.0+Local or hosted2.6kaug 2026The basic communal whiteboard that keeps working: persistent rooms, live cursors, free hosting, and almost no workshop theatre.
The catch vs LucidsparkWBO is a bare communal canvas without Lucidspark's templates, voting, timers, structured activities, integrations, or enterprise controls.
Install, platforms & data +
- platforms
- webself-hostedthey host it
- install
- Use the free hosted instance, or run the Docker image/Node.js server
- setup
- None for the public instance; self-hosting needs Docker or Node.js, a persistent writable volume with the expected user ownership, backups, and a public URL/TLS
- your data
- Boards are persisted as JSON files in the server's data directory; a Docker deployment must mount that directory, while public-hosted boards live on the operator's server

Should I vibe-code or build my own Lucidspark clone from scratch?+
Our build verdict for Lucidspark is KINDA (the core, yes. the polish, no). The visible whiteboarding loop is buildable, but a credible replacement needs more than the first screen. Lucidspark earns its keep through interaction polish, collaboration, so expect a weekend or multi-day build and a narrower personal scope.

Excalidraw is faster for sketching but omits many structured facilitation features such as advanced voting, timed activities, and enterprise workshop controls.
