A live and interactive repo graph (edit, reorder, fixup, merge commits…),
Unlimited undo / redo of almost all operations (even rebases and merges),

Features that don’t even exist natively in Git like a visual commit splitter or a unified reflog browser,
Instant search across the entire repo including diff contents,
A ridiculously fast UI, often faster than the command line.
GitUp was created by @swisspol in late 2014 as a bet to reinvent the way developers interact with Git. After several months of work, it was made available in pre-release early 2015 and reached the top of Hacker News along with being featured by Product Hunt and Daring Fireball. 30,000 lines of code later, GitUp reached 1.0 mid-August 2015 and was released open source as a gift to the developer community.
