CheckLink Browser Extension: Check Pages Faster Without Leaving the Browser
How the CheckLink browser extension fits into a fast, privacy-first workflow for checking pages and links.
Why a browser extension helps
When you are already looking at a page, copying the URL into a different tab is one more step than you need. A browser extension reduces friction by sending the page you are viewing to CheckLink when you choose to check it.
That matters when the link came from email, chat, a QR code, a campaign, or a page that already feels suspicious. Faster access makes careful checking more likely.
Check the current page or a selected link
The extension is designed for user-triggered actions. You can open the current page in CheckLink, send a selected link from the browser menu, or jump into a related tool such as the redirect checker or quick report.
The workflow stays privacy-first because CheckLink only receives the URL when you choose a scan action.
Keep the workflow clear
The best browser shortcuts are simple: open the tool, inspect the destination, and decide whether to keep going. The extension does not need to read page contents to be useful.
CheckLink uses the same risk-signal approach on the web and in the extension. It does not claim that a site is guaranteed safe.
Which browsers are supported
CheckLink works with Chrome and compatible Chromium-based desktop browsers. Firefox and Safari versions are not currently available.
That keeps the first release focused while leaving room for future browser support if the product direction changes later.
What CheckLink checks
Use the browser extension for quick access, then let CheckLink inspect URLs, redirects, final domains, lookalike patterns, punycode, and other available risk signals.
For sensitive cases, use manual review after the quick check. The extension is a shortcut, not a verdict.
