About

Block Service Worker registration and Cache Storage access on domains you choose.

Some websites aggressively use Service Workers in ways that cause stale content, excessive disk usage, or interfere with development. Service Worker Blocker
lets you maintain a blocklist of domains where these APIs are completely disabled.

Features
• Domain blocklist synced across Chrome profiles
• Wildcard support — *.example.com matches all subdomains
• Built-in presets (e.g. Feishu/Lark) and custom presets you create
• One-click add for the current tab's domain
• Per-domain cleanup: unregister SWs and clear caches
• Clean All: bulk cleanup across every blocked domain
• Lightweight, no background network requests, fully open source
