Excalidraw
open sourceMITLocal or hosted129kaug 2026Excellent collaborative flowcharts, wireframes, and loose visual thinking; it does not pretend to be a proper document editor or structured mind mapper.
The catch vs WhimsicalExcalidraw is excellent for sketches but does not replace Whimsical's structured documents, dedicated mind maps, polished wireframes, and formal flowchart toolkit.

- 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

CryptPad
open sourceAGPL-3.0+Local or hosted7.8kaug 2026Private collaborative docs, whiteboards, diagrams, slides, and Kanban in one suite; rougher edges, fewer tasteful shortcuts, and no native mind-map mode.
The catch vs WhimsicalCryptPad lacks native mind maps and polished wireframe components, and its diagramming and document experience is considerably rougher than Whimsical.
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

AFFiNE
freeMITLocal or hostedDocs, whiteboards, databases, mind maps, tasks, and presentation frames in one finished app; the free hosted limits are tolerable for one person or a tiny team.
The catch vs WhimsicalAFFiNE's diagram and wireframe libraries, keyboard-driven speed, and visual refinement are less mature than Whimsical's focused collaborative editor.
Install, platforms & data +
- platforms
- desktopmobilewebthey host it
- 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
