Kactus

Introducing true design version control without changing your tools. Manage changes, document work and keep your team in sync. Enjoy all the benefits of git with our simple UI, leaving you more time to focus on what matters — your design. Create branches, collaborate with other designers or developers, and commit changes without touching the command line. Every pixel is completely open source. Build the features you need and become a part of future Kactus releases. It brings the entire git flow to sketch: branches, pull requests, team collaboration (you can work on the same file and automatically merge the changes), etc. You can share pages across multiple sketch files. You can publish pages on the internet and import them in another project (soon)!
