WebTester Pro — HACKERRR

WebTester Pro is a browser extension for authorized web application security testing, bug bounty research, and security learning.

It includes a payload browser, encoder and decoder tools, JWT decoder, regex library, notes manager, checklist manager, wordlist manager, recon command references, report generator, context menu helpers, and a Firefox sidebar.

The extension is designed for legal security testing only. Use it only on systems you own, lab environments, bug bounty programs where the target is in scope, or systems where you have explicit written permission.
