Capture payloads from any page.

The PayloadIQ extension detects JSON on the current tab and sends it to the analyzer. Your payload is encoded entirely in the URL hash — it never touches our servers and is never logged. Only you can see it.

Download & Install

Download the ZIP, then load it unpacked in Chrome. Webpages cannot auto-install extensions — this is a Chrome security requirement.

Prefer no extension?

Use the bookmarklet instead. Drag the link below to your bookmarks bar, then click it on any page with JSON to open it in PayloadIQ. No install required — works in any browser.
