Nifty Undo Tree
Never lose an edit to undo again: every version of a file is kept in a tree, including branches you undid and typed over, with diffs and one-click restore.
Maintained. No sign-in. No telemetry. Works in VS Code, Cursor, Windsurf, VSCodium and other editors that use Open VSX.
Features
- Undo without fear. Normally, if you undo a few steps and then type something, the undone work is gone for good. Nifty Undo Tree keeps it. Every version of the file stays in a tree, including branches you undid and typed over.
- See your history. The Undo Tree view in the Explorer lists the active file's versions, newest first, with when each was made and how many lines changed. Places where you undid and started over show the abandoned branches underneath, one click away.
- Compare and restore. Click a version to compare it with the file as it is now. Click Restore to bring it back. A restore is a single edit, so plain Ctrl+Z takes you back again.
- Works with normal undo. Ctrl+Z and Ctrl+Y move through the tree as usual. Nothing about your editing changes; the extension only watches.
- Light. Edits made close together become one version (1 second by default), each file keeps at most 500 versions (abandoned branches are dropped first), and very large files are skipped.
- Works in the browser on vscode.dev and github.dev.
