I built a tool to manage old Chromium versions for browser testing

I recently needed to reproduce a frontend bug on an older version of Chrome, and I found the process of managing different Chromium versions pretty annoying.

I ended up building a small tool that lets me install and manage older Chromium versions locally.

It supports multiple Chromium versions side by side, which makes it easier to reproduce browser-specific issues and test compatibility.

I'm curious how you guys usually handle testing against older browser versions. Do you use Docker, BrowserStack, virtual machines, or something else?

I built this mainly to solve my own problem, but I'd be interested in hearing how others approach it.
