Every time I do a website audit I run into the same problem. The checklist is open in one tab, the page I'm auditing is in another, and every time I need to mark something off I lose my place. Multiply that across 15 pages and it turns into a lot of unnecessary context switching.

I looked for a browser extension that would keep a checklist open next to the page I'm working on — something that lives in the side panel, not in a separate tab or window. I didn't find anything that fit, so I built it.

What it does

CheckRun is a Chrome extension that runs in the browser side panel. The core model is simple: build a template once, run it against any page.

When you open a run, the extension captures the URL and page title automatically. You go through each item marking it Pass, Fail, or N/A, leave comments where needed, and save the run when done. Every completed run is stored in history with its date, URL, and full item-level results.
