FAQ

Is POSH open source?

Client and back-end applications are not open source.

But we maintain our own gems and actively contribute to anything we use.

Does POSH work offline?

Yes. Run posh sync with an internet connection to download or update documentation. After that, search and read locally. Documentation only syncs when you run the command.

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.
