Welcome to hexbuffer
The Unified Application Security, API Diagnostics, and AI Automation Workspace
Redefining Web Application Reconnaissance & Security Testing
hexbuffer is a next-generation desktop platform designed to unify web application security diagnostics, API request crafting, network traffic analysis, visual workflow automation, and autonomous AI guidance into a single, seamless environment.
Built for modern developers, security researchers, QA engineers, and system architects, hexbuffer eliminates tool fragmentation by bringing network proxying, automated parameter fuzzing, visual end-to-end regression, and AI-driven intelligence under one roof.
Why Choose hexbuffer?
Traditional web application testing often requires switching between disjointed browser extensions, standalone API clients, CLI tools, external AI chats, and isolated notes applications. hexbuffer replaces this fragmented experience with an intuitive, integrated desktop suite.
No Web Tool Sprawl
Access your proxy, API client, fuzzers, shell terminal, and documentation in a unified workspace without context switching.
Autonomous AI Copilot
Leverage built-in AI agents that inspect live network traffic, generate test payloads, manage terminal commands, and draft documentation in real time.
High-Speed Traffic Diagnostics
Intercept, inspect, and modify HTTP/HTTPS and WebSocket traffic on the fly with millisecond responsiveness and deep packet analysis.
Visual Workflow Automation
Construct node-based automation pipelines and visual regression tests without writing tedious boilerplate code.
Core Capabilities at a Glance
1. Real-Time Traffic & Interception
Capture complete web interactions, monitor live requests and responses, filter by domain scope, and pause in-flight traffic to edit payloads before they hit your servers.
2. Request Crafting & Fuzzing
Replay and modify requests effortlessly in the Repeater, execute high-speed parameter fuzzing in the Invoker, and perform context-aware vulnerability checks for SQL Injection and XSS.
3. Out-of-Band Collaborator
Detect asynchronous callbacks, webhooks, and out-of-band interactions across DNS, HTTP, and SMTP protocols to verify asynchronous application behavior.
4. AI-Powered Workspace & Developer Tools
Collaborate with an integrated AI assistant, execute visual E2E regression tests, spin up API mock servers with Mock Forge, manage project tasks with Kanban, and encode/hash payloads instantly.
