devdocs.el VS devdocs-macos

emacs integration: https://github.com/astoff/devdocs.el

devdocs.el: Documentation reader with quick and handy lookup commands. It is similar to the built-in Info reader, but has a different (likely larger) document coverage.

I use this (https://github.com/astoff/devdocs.el) emacs package to download devdocs locally and access them from emacs, which is pretty great.

Support for other languages is a good point. Most don't ship info documentation. :P If you want something inside a normal Emacs buffer rather than a separate browser-like application, maybe you'd enjoy devdocs.io and astoff's devdocs.el package.

+1. I'm using an amazing Emacs package that treats DevDocs kinda like Dash: https://github.com/astoff/devdocs.el

info-like: https://github.com/astoff/devdocs.el

devdocs.el to read documentation

Wow, so many devdocs packages! Of the two I mentioned, devdocs-browser is the one in the emacs-devdocs-browser repo you found. But the other one I was thinking of didn't turn up in your search: devdocs. I wasn't aware of the others you found, probably because they aren't on GNU ELPA or on MELPA.

The advantage of being open source is there is an entire ecosystem developed around it. Apart from offering more docs than Dash, it also has a VS.Code Extension, native macOs and Linux apps and more.
