Browser Extension · Bookmarklet

Capture payloads from any page.

Right-click any JSON response in the network tab or select text on a page and send it straight to the playground. Or click the toolbar popup to analyse the last captured payload without leaving your tab. Your payload is encoded entirely in the URL hash — it never touches our servers and is never logged. Only you can see it.

🖱️
Right-click JSON
Select any JSON text on a page, right-click, and send it directly to PayloadIQ — no copy-paste required.
🧩
Toolbar popup
Click the extension icon to analyse the last captured payload in a compact popup without switching tabs.
🔒
No upload
Captured payloads stay in the extension and are passed to the browser-local playground. Nothing is sent to a server.

◧ PayloadIQ — drag to bookmarks bar

Tip: if your bookmarks bar is hidden, press Ctrl+Shift+B (Chrome) to show it, then drag. Or use Copy bookmarklet and paste it as the URL of a new bookmark.
