Built for the thing you actually do all day
Most CyberChef use is one operation on something you just copied. The extension optimises for that, and keeps the full app one click away for everything else.
-
01
A tool is an operation plus its arguments
AES-CBC decrypt (prod key)is one click, not eight fields. Save the same operation twice with different arguments — that is the point. Your tools sync with your browser profile. -
02
Popup or side panel
Use it as a quick popup, or dock it as a side panel that stays open while you work. Pick either; switch whenever.
-
03
Right-click to transform
Select text on any page, right-click, and send it straight to one of your tools.
-
04
Grab exactly the part you want
Point at the page and the element under your cursor highlights, the way DevTools does. Click to pull it in — as rendered text, HTML, or raw. Widen to the parent with the arrow keys when you want the whole table, or the whole page.
-
05
All 501 operations, offline
The complete app ships inside the extension and opens in its own tab. On a plane, on an air-gapped box, on a bad hotel connection — same tool.
-
06
Nothing is sent anywhere
The extension makes no network requests at all — check it in DevTools. It declares no content scripts, so a page is read only when you ask it to.

Edge installs the Chrome build. Both are Manifest V3, and neither asks for a permission it does not use — the extension reads a page only when you press Grab.
