What Can You Do?

Modern web security testing is fragmented. 0xbuffer brings it all into one workspace.

Watch Live Traffic

See every HTTP request and response in real time. Filter by URL, method, status, or custom tags.

Intercept & Tamper

Pause traffic mid-flight. Edit raw HTTP before it reaches the server — or drop it entirely.

Repeat & Craft Requests

Compose HTTP requests from scratch and send them to any endpoint.

Automate Request

Run high-speed brute force and fuzzing campaigns with marked payload positions.

Automate Browser

Let AI drive a browser to crawl target websites on your behalf.

Build Recon Reports

Document findings as you work. Create structured reports with markdown sections.

Utility Toolkit

Encoder/decoder, hash generators, subdomain enumeration, port scanning, and more.

Automate WorkflowsSoon

Chain tools together into automated pipelines. let 0xbuffer handle the repetitive work.

AI Assistant

Get contextual suggestions, payload ideas, and guided remediation steps powered by an AI security analyst.

CodeSoon

Full-project C/C++ & Rust IDE with one-click scaffolding, integrated build/run output.

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?

Built for anyone who needs to inspect, test, and document web applications.

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.

A local-first desktop app

0xbuffer runs entirely on your machine. No cloud, no accounts.

Entirely local — runs on your machine, not on our servers

No accounts — install and start working immediately

Zero cloud — everything stays on your machine

Try 0xbuffer on your next target.

A desktop app for web app recon, traffic inspection, and security testing — all in one place.
