How does 'Smart Fallback' work?

If the primary CORS proxy fails to retrieve a page, Web Cache Viewer automatically cycles through multiple high-performance proxies (AllOrigins, CORSProxy.io, etc.) until a successful connection is established.

Is my browsing history private?

Yes. Browsing history and cached content are stored entirely in your browser's localStorage. No URLs or page contents are sent to our servers.

Why do some images not load?

Some websites use hotlinking protection (referral checks) that prevents images from loading when viewed outside their original domain. Web Cache Viewer detects this and provides a placeholder to maintain layout integrity.

Web Cache Viewer Documentation

Web Cache Viewer is a production-ready tool for archiving and reading web content with high fidelity and full privacy. It replicates the core functionality of search engine caches—without the dependency on third-party availability. Open Web Cache Viewer.

Content Recovery & Archiving

When a webpage goes down or content is deleted, search engine caches (like Google or Bing) often still hold the data. Web Cache Viewer helps you:

Retrieve Snapshots: Instantly fetch the latest cached version of any URL.
Archive Locally: Save the content to your local history for permanent offline access.
Wayback Integration: One-click access to the Internet Archive (Wayback Machine) for historical versions.

CORS Proxy Bypassing

Standard browsers block cross-origin requests for security. Web Cache Viewer bypasses this using a Smart Proxy Fallback system:

Automatic Selection: The tool tries multiple proxies sequentially if the target site blocks specific IP ranges.
Customizable: Manually select specific proxies (e.g., Cloudflare Workers or AllOrigins) if you have preferred routing.
Full Privacy: While proxies see the URL being fetched, the *content* is parsed and rendered entirely on your machine.

Smart Content Extraction

Unlike simple "View Source" tools, Web Cache Viewer uses a semantic parsing algorithm:

Container Targeting: It identifies <article>, <main>, or high-density paragraph containers.
Noise Reduction: Strips ads, trackers, cookie banners, and sticky navigation overlays.
Readability Mode: Reformats the text into a clean, typography-focused interface similar to a Kindle or Pocket reader.

Local-First Storage

Your research remains private. The tool uses a 5MB local storage quota:

Zero Tracking: No external database stores your history.
Audit Metrics: A real-time storage monitor shows you how much space your cached pages are consuming.
Export Options: Export any cached page as a standalone HTML file or plain text for your own records.

Frequently Asked Questions

Can it bypass paywalls?
In many cases, yes. Since proxies often appear as search crawlers or different geolocations, they can sometimes fetch content that is otherwise restricted to your local IP.

What is the 'Refresh Cache' button for?
It re-fetches the URL through the proxy chain to see if a newer version of the page has been indexed or if the site has come back online.
