Mindmap Ziin: A Free Mindmap SaaS service

Mindmap Ziin started as a scratch pad for visual thinkers and turned into a polished, free SaaS built by a tiny team obsessed with flow. If you spend more time prepping your canvas than capturing ideas, this one’s for you.

Why it feels different

  • Instantly ready workspace Open the editor and a centered root node, zoom-fit canvas, and shortcut hints are already in place. No toolbars to rearrange or zoom to rescale.

  • Keyboard-native UX Enter toggles inline edit, Tab adds a child, A adds a standalone node, M opens the context menu near your focus, and the arrow keys walk connected nodes or edges. You can map an entire sprint with barely a mouse click.

  • Rich nodes and edges Images, PDFs, embeds, and draggable edge inspectors all live directly on the canvas. PDF nodes include a built-in viewer modal so you can present without popping out of the map.

  • Smart sharing Each map is versioned in its own Git branch (GitHub or local Git). Flip a share badge when you’re ready, or stay private in guest mode—the data lives in your repo.

Version history you can trust

Every save is a Git commit. If you ever need to revisit past thinking, the version view lets you jump back to any earlier state to inspect it before deciding what to restore.

Get started

  1. Sign in (or stay in guest mode).
  2. Create a map; the root node is created and auto-saved so you never lose the blank slate.
  3. Use Tab, Enter, and M to run. Paste images or drag PDFs as needed.
  4. When you want to share, hit save—Git commits the branch, and share badges appear in both the dashboard and editor.

Mindmap Ziin is free to use, easy to self-host, and built openly with the community. If you like mind maps that feel more like thinking and less like wrangling tooling, give it a spin and let us know what you build.
