Polar is proudly built open source (Apache 2.0). You can find our entire product & docs on our GitHub

You can develop on Polar in GitHub Codespaces. The environment is pre-configured to contain (most) of the tools that you'll need, and will help you to configure the integration between Polar and GitHub (see .devcontainer/README). Using an instance with at least 4 cores is recommended.

Open in GitHub Codespaces

You can also develop on Polar locally on your computer. It's the recommended way of working if you want to make contributions on a regular basis.

Documentation on how to setup a development environment is incoming. Until then, if you're feeling adventurous checkout our repository structure below and clients/README and server/README in particular.
