17,000 Browser Mod devices cleared by a Claude-written script

Browser Mod created a device for every browser session and slowed Home Assistant to a crawl, until a Python script from Claude deleted them all.

The full story

The Browser Mod add-on created a device for every browser session the poster opened, leaving more than 17,000 devices and a nearly unusable Home Assistant interface. They could not even uninstall it, because the screen would not load with so many devices.

They had Claude write a Python script that deleted all the entries, and the system is back to running fast. Their advice is to take a good backup before installing Browser Mod.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count).
