APIVoid Script Stop by APIVoid

A simple script blocker that blocks third-party JavaScript on websites by default. See exactly what each page tries to load, allow scripts you trust, block the ones you don’t, and manage everything from a single popup.

First-party scripts (served by the website you’re visiting) continue to load normally, but can also be blocked with a single toggle for stricter protection on untrusted pages.

The popup shows every script requested by the current page, with clear allowed/blocked indicators and one-click controls for temporary or permanent allow/block rules.

A built-in trusted list (Stripe, PayPal, Google APIs, and 200+ other commonly used providers) helps most websites work out of the box. Additional features include a searchable history of blocked scripts, per-site disable support, subdomain-inclusive matching, and full backup and restore of your entire configuration to a JSON file.

Very simple to use:

• Click the pinned icon on the toolbar
• See blocked and allowed scripts for the current page
• Use Allow, Block, Whitelist, or Blacklist for any host
• Disable the extension on specific websites if needed
• Export and import your configuration at any time

No uploads, no external servers, no telemetry, everything runs locally in your browser. All whitelist rules, blacklist rules, exclusions, and history stay only in your local extension storage.
