Zxc – Rust TLS proxy with tmux and Vim as UI, BurpSuite alternative
Ditch Burp Suite’s bloat for zxc, a Rust-built, terminal-based proxy that uses tmux and Vim to intercept HTTP/S and WebSocket traffic. It captures requests for debugging, security testing, or tweaking—fast and lean. # Key Features - Disk Wizardry: Stashes massive datasets on disk-100k+ entries without breaking a sweat. - Addons: Boost your workflow with default support for ffuf and sqlmap, or craft your own addons for extra fun. - Buffer Tweaks: Edit variables in a popup (e.g., b:host, b:scheme) in Interceptor/Repeater to twist requests. - Config Control: TOML files for global…
In plain words
Zxc is a terminal-based HTTP/HTTPS and WebSocket proxy built in Rust that uses tmux and Vim for its interface. Designed for developers and security testers, it intercepts and captures traffic for debugging and security testing. It stores large datasets on disk, supports add-ons like ffuf and sqlmap, allows request editing through buffer variables, and includes content and domain filtering via TOML configuration files.

It captures requests for debugging, security testing, or tweaking—fast and lean. # Key Features - Disk Wizardry: Stashes massive datasets on disk-100k+ entries without breaking a sweat. - Addons: Boost your workflow with default support for ffuf and sqlmap, or craft your own addons for extra fun. - Buffer Tweaks: Edit variables in a popup (e.g., b:host, b:scheme) in Interceptor/Repeater to twist requests. - Config Control: TOML files for global ($HOME/.config/zxc/config.toml) or per-session tweaks. - Content Filtering: Skip requests based on the request Content-Type header. - Domain Filtering: selectively include or exclude specific domains, offering granular control over which traffic is proxied or relayed, with support for wildcards like *.example.com - Edit Config on the Fly: Tweak session settings live from History in a popup-changes hit instantly or refresh manually if edited outside. - Encoding Tricks: Base64 or URL encode/decode in Visual mode-sneaky. - Extended Attributes: Supercharge your workflow with `.req` files automatically tagged with critical metadata (e.g., user.host, user.http) - break free from the sandbox and unlock powerful integration with external tools like scripts or analyzers. - Extension Filtering: Skip requests based on the requested contents extension `.mp3`, `.mp4` etc. - History Display Filters: Tweak History logs by host, URI, or status code with Vim regex flair. - History Window: View and filter all traffic in real-time. - Interception Queue: Manage pending requests and responses in real-time—view the queue with scheme and host details, then forward, drop, or tweak them as they pile up in the Interceptor window. - Malformed Requests: Custom HTTP/1.1 parser for sending quirky, security-testing requests. - Repeater Window: Resend and tweak HTTP or WebSocket requests with ease - Request Sharing: Share requests freely between windows for seamless tweaking and testing. - Search Superpowers: Search requests or responses and add to Vim’s quickfix/location lists. - Session Management: Create named sessions and attach to older sessions to resume work seamlessly. - Traffic Interception: Edit requests and responses live in Vim. - WebSocket History: A clear, organized history view of all WebSocket traffic with `.whis` files for a full overview, or dive into single-session details with `.wsess` files. - WebSocket: Proxy and replay WebSocket traffic.

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
