Overview

Product summary

Review the store description, core capabilities, and common use cases.

Strict URL Whitelist is a Chrome extension that enforces navigation only to explicitly approved URLs. It uses Chrome’s high-performance declarativeNetRequest API to allow or block requests based on domain, path, and optional query parameters — all defined through local configuration.

The extension is lightweight, script-free, and does not interact with page content. It applies all rules at the network level using a background service worker, ensuring reliable, zero-interaction enforcement.

Technical Architecture

Allowlisting Mechanism

Filtering is implemented through chrome.declarativeNetRequest.updateDynamicRules(), which allows near-instant control over navigation. The logic includes:

All main_frame requests are blocked by default using a global redirect rule.
