devdocs-macos VS devdocs.el

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.

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.
