Localhost No Cache
Extension Actions
Intercepts all localhost / 127.0.0.1 requests and forces no-cache response headers.
Localhost No Cache helps you avoid stale files during local development.
It intercepts requests to localhost and 127.0.0.1 and adds no-cache request headers so Chrome always revalidates instead of serving old disk cache content.
Use it when working on frontend apps, APIs, SPAs, hot-reload setups, or any local server where cached assets cause confusion.
A simple popup toggle lets you turn interception on or off anytime.
The enabled/disabled state is saved automatically.
Key features:
Targets localhost and 127.0.0.1 across all ports.
Applies to common resource types including HTML, JS, CSS, images, XHR/fetch, and WebSocket-related requests.
Adds request no-cache headers to force fresh content checks.
One-click enable/disable control in the extension popup.
Lightweight Manifest V3 extension with no external services.
