Hunter Helper

Encode/decode, hashing, JWT, timestamps, public IP and more for bug bounty hunters. Burp-style chained decoder with smart decode.

Hunter Helper is a compact toolbox for bug bounty hunters and penetration testers, available from your browser toolbar. What it does: • Encoder/decoder with chaining – convert text between common web encodings and chain several steps together, similar to Burp Suite's Decoder. Each step's result is shown so you can follow the transformation. • Smart decode – automatically detects and unwraps text that has been encoded several times. • Hashing – generate common hashes of any input, one at a time or all at once. • JWT tool – decode a token, edit its header and payload, re-encode it, and see its date claims as readable times. • Timestamp converter – view the current Unix time and convert between timestamps and human-readable dates. • My IP – shows your public IP address with the current local and UTC time, and copies them as a ready-made note for your reports. • Utilities – format or minify JSON, count characters, and work with IP addresses and subnets. Your inputs are saved in your browser so they are still there when you reopen the popup. All processing happens locally; the only network request is the public IP lookup in the My IP tab.
