OctoPermalinker is a free browser extension available on Chrome. Developed by Joseph Frazier, this add-on falls under the category of Browsers and specifically the subcategory of Add-ons & Tools.

The main purpose of OctoPermalinker is to address the issue of broken GitHub links. It achieves this by searching GitHub comments and files for links to files on branches. When it finds such a link, it adds a link to the location where the branch pointed at the time the comment or file was made or updated. This functionality helps users avoid following links that have become broken after being posted.

For those unfamiliar with the problem of broken GitHub links, OctoPermalinker provides a valuable solution. By ensuring that the links point to the correct location, users can have a smoother browsing experience and avoid wasting time on dead ends.

OctoPermalinker is a useful tool for anyone who frequently uses GitHub and wants to ensure that the links they come across are still valid. With its simple and straightforward functionality, it is a valuable addition to the arsenal of GitHub users.
