FAQ

Is POSH open source?

We maintain open-source libraries that power our services, including yard-markdown, webhukhs, and rdoc-markdown. We also actively contribute to the libraries we use.

However, two of our backend services are private, and the POSH client itself is not open source.

Does POSH work offline?

Yes. POSH is a local-first app. You only need an internet connection to download or update documentation.

Which operating systems are supported?

POSH runs on macOS and Linux. Install it with Homebrew, use the AUR package on Arch Linux, or download an executable from GitHub Releases.

What programming languages are supported?

POSH supports Ruby. Python and Go support are planned.
