Velopack is an installation and auto-update framework for cross-platform desktop applications. It's opinionated, extremely easy to use with zero config needed. With just one command you can be up and running with an installable application, and it's lightning fast for your users, too.

Be sure to check us out on GitHub and join our Discord for any questions/support!


To enable your application to make full use of Velopack, you need to do 3 things:


Integrate the SDK & check for updates

We have client libraries for some languages below, or if we don't support your language yet you can use our CLI.
