A Text-Based Compositor For Modern Terminals.
Tattoy can generally be thought of as a framework for adding eye-candy to your terminal. It is purely text-based so works in any terminal emulator that supports true colour. "Graphics" is rendered with UTF8 half-blocks (▀,▄). Whilst most of its effects are for getting you street credibility it also has more powerful features based around its awareness of terminal contents. For example it can detect and auto adjust text contrast whilst remaining faithful to the terminal's palette.

A research project to add some brrrrrr to Burp.
"burpference" started as a research idea of offensive agent capabilities and is a fun take on Burp Suite and running inference. The extension is open-source and designed to capture in-scope HTTP requests and responses from Burp's proxy history and ship them to a remote LLM API in JSON format. It's designed with a flexible approach where you can configure custom system prompts, store API keys and select remote hosts from numerous model providers as well as the ability for you to create your own API configuration. The idea is for an LLM to act as an agent in an offensive web application engagement to leverage your skills and surface findings and lingering vulnerabilities. By being able to create your own configuration and model provider allows you to also host models locally via Ollama to prevent potential high inference costs and potential network delays or rate limits.

A Terminal UI for Terraform Plans.
An interactive terminal UI for reading Terraform plans. A Terraform configuration is a graph, and a plan is a proposed change over that graph. Scrolling through hundrends of lines of terraform plan output makes that structure almost impossible to see. tfplantui renders the plan as its dependency graph — laid out in columns by dependency depth — and lets you walk it with the arrow keys, expanding any resource to see a color-coded before → after diff of its attributes.
High speed TLS signature filtering.
Instead of taking the full JA4 hash to fingerprint traffic which is slow to calculate and is hard to implement in a BPF filter, I take a Jenkins hash of the sorted supported ciphers in any given TLS request. To similar effect as JA4, keeping fingerprinting usefulness. Switching to a non-cryptographic hashing algorithm is okay here because any given attacker with enough skill could replicate the ciphers of another client, so any hash reversing would be useless or at best force the attacker to implement a different amount of hashes.
