rep+ is a lightweight Chrome DevTools extension inspired by Burp Suite's Repeater. I often need to poke at a few requests without spinning up the full Burp stack, so I built this extension with the help of LLM (Gemini 3) to keep my workflow fast and focused.
-
No Proxy Setup: Works directly in Chrome. No need to configure system proxies or install CA certificates like in Burp Suite.
-
Capture & Replay: Captures every HTTP request you trigger while testing. Replay any request and freely manipulate the raw method, path, headers, or body to probe endpoints.
-
Filters & Regex: Powerful search across URL, headers, and body. Toggle Regex Mode for advanced pattern matching (e.g., finding specific tokens or IDs).
-
Converters: Right-click context menu to instantly encode/decode data:
- Base64
- URL Encode/Decode
- JWT Decode (view payload instantly)
- Hex / UTF-8
-
Screenshots: Built-in screenshot tool to capture the request/response pair for bug reports.
-
History & Navigation: Undo/redo support for edits and history navigation for selected requests.
-
Starring: Pin important requests to keep them at the top of your list.
-
Clear Workspace: Instantly clear all captured requests with a single click to start a fresh session.
-
Export & Import: Export requests as JSON to share findings with teammates or import them later. Perfect for rep+ ↔ rep+ workflows.
-
Bulk Replay: Burp Suite Intruder-style attacks with four attack modes:
- Sniper: Tests each position independently with its own payloads
- Battering Ram: All positions receive the same payload
- Pitchfork: Zips payloads across positions (index-wise)
- Cluster Bomb: Tests all combinations (Cartesian product)
Mark multiple parameters with
§, choose your attack type, configure payloads (List or Numbers) for each position, and inspect detailed results for every attempt. Includes pause/resume functionality for long-running attacks.
- Clone the repository:
git clone https://github.com/bscript/rep.git
- Open Chrome Extensions:
- Navigate to
chrome://extensions/in your browser. - Enable Developer mode (toggle in the top right corner).
- Navigate to
- Load the Extension:
- Click Load unpacked.
- Select the
repfolder you just cloned.
- Open DevTools:

F12or right-click -> Inspect. - Look for the rep+ tab (you might need to click the
>>overflow menu).

This combo makes rep+ handy for bug bounty hunters and vulnerability researchers who want Burp-like iteration without the heavyweight UI. Install the extension, open DevTools, head to the rep+ panel, and start hacking. 😎
