Excalimate

Excalimate is a keyframe animation tool built on top of Excalidraw. Excalidraw is great for sketching diagrams. But what if those diagrams could move? Excalimate gives you a full animation timeline where you can add keyframes for opacity, position, scale, rotation, and draw progress (arrow/line draw-on effects). You get a camera system with pan/zoom animation and aspect ratio control. When you're done, export as MP4, WebM, GIF, or animated SVG. Key features: Full Excalidraw editor — draw, edit, resize, text, arrows, everything Excalidraw does Keyframe animation — opacity, position, scale, rotation, draw progress Visual timeline — per-element tracks, clip markers, scrubbing Sequence reveal — stagger-reveal multiple elements with one click Camera frame — animated pan/zoom, aspect ratio control Export — MP4 (H.264), WebM (VP9), GIF, animated SVG E2E encrypted sharing — share via URL, encryption key stays in the hash fragment MCP server — AI agents can create scenes, add animations, and preview live Dark mode — full light/dark theme support The MCP server is what makes this really interesting. Install it with npx @excalimate/mcp-server , connect your AI assistant, and watch it create animated diagrams while you see every change in real-time. It's like pair-programming but for motion design. Open source, free to use. No sign-up required.
