Service Worker Manager
Product development, Developer tooling, Chrome extension
A free Chrome extension for stubborn localhost state
We built it after a client project kept leaving stale service workers and caches behind on reused localhost ports, making unrelated projects look broken. The extension gives developers a fast current-origin view and a clean recovery path.
The scope stays intentionally tight: inspect the active origin, unregister service workers, clear named caches, and reset both in one action. It is free to use, aimed at developers, and designed to save minutes of confusion every time local state goes bad.
We built Service Worker Manager for ourselves first. Stale workers on reused localhost ports kept turning healthy apps into false negatives. Once it became part of our regular debugging flow, publishing it for other developers was the obvious next step.
