digit - learn git by visualizing it

Digit shows a realtime visual representation of a git repo structure, making it easier to understand how git works and what is the effect of each and every git command you run.

Digit is meant to be a learning tool, developed for our mid-level git workshop ( As such, it is not designed to scale to large repositories.

How does it look like

Main interface


  • monitors a local git repo
  • realtime updates using fsnotify and websockets
  • optionally monitors a second repo to experiment with remotes, push, pull, fetch, etc
  • shows git graph, including unreachable nodes
  • shows references: tags, branches, HEAD, stash pointers
  • commit metadata in tooltip
  • display current repo status (as in "output of git status")
  • visualizes node ancestry (for reachability)

Binary downloads

Digit requires git to be installed on your machine

Local and remote repo

Local and remote repo


digit [--bind-to <bind-address>:<bind-port>] local_repo_path [origin_repo_path]

and point your browser to http://localhost:9000 (or any other address specified in --bind-to)

Both paths must reside on the local filesystem (no network support yet).

Building from source

This repo uses a submodule in embedded_data/graph-algorithm.

When cloning, make sure to use --recursive in order to properly initialize the submodule.

The build system relies on docker and GNU Make.

  • make local: builds for the local os/arch
  • make all: builds for all architectures

Known Limitations

  • just a learning aid
  • not meant to scale (tested with repos with a couple hundred commits)
