0xbuffer

The All-in-One Security Testing Workstation

See everything.
Break everything.
Document everything.

0xbuffer is a desktop application that puts a complete security testing toolkit at your fingertips.

What Can You Do?

Modern web security testing is fragmented. 0xbuffer brings all of that into one seamless workspace.

Watch Live Traffic
See every HTTP request and response flowing through your device in real time. Filter by URL, method, status, or custom tags.
Intercept & Tamper
Pause web traffic mid-flight. Edit the raw HTTP before it reaches the server — or drop it entirely.
Repeat & Craft Requests
Manually compose HTTP requests from scratch and send them to any endpoint.
Automate Attacks
Run high-speed brute force and fuzzing campaigns with marked payload positions.
Sniff Raw PacketsComing Soon
Capture raw network traffic from Wi-Fi or localhost interfaces. View hex dumps, reconstruct TCP streams.
Automate BrowserComing Soon
Let AI drive a browser to crawl target websites on your behalf.
Analyze with AIComing Soon
Ask an AI assistant to review your discovered assets against OWASP Top 10 frameworks.
Build Recon Reports
Document your findings as you work. Create structured reports with markdown sections.
Utility Toolkit
Built-in encoder/decoder, hash generators, subdomain enumeration, port scanning, and more.

How Is It Different?

0xbuffer combines real-time traffic interception, manual request crafting, automated attacks, AI-driven reconnaissance (AI feature currently under development), and professional report building in a single desktop application. No web-based tool sprawl. No juggling five different windows. Just open 0xbuffer and get to work.

Who Is It For?

Penetration Testers
A complete workstation that replaces a patchwork of tools.
Bug Bounty Hunters
Find, verify, and document vulnerabilities faster.
Security Researchers
Deep traffic analysis combined with AI-assisted discovery.
Developers & QA
Debug APIs and test endpoint behavior manually.

0xBuffer is getting better and better day after day and we are happy to share our results with you.
