Iris is a local-first MCP server that scores AI agent runs for quality, safety, and cost using 20 built-in deterministic rules, an optional LLM judge, and a web dashboard — all on your machine with no account or telemetry.

Pixel FX Forge is a browser-based procedural generator for creating animated pixel-art ability effects, allowing users to design and export game-ready VFX.

py-spy is a low-overhead sampling profiler for Python programs that allows visualization of program execution without modifying code or restarting the process.

Sophia Stack is a modern, atomic X11 desktop system designed to replace ambient trust with explicit authority boundaries and isolated namespaces.

TUnit-native math assertion library for .NET: fluent tolerance, sequence, statistics, linear algebra, number theory, and 3D geometry assertions generated into TUnit's Assert.That pipeline; AOT-compatible and reflection-free.

A simple terminal UI for git commands that simplifies complex workflows like interactive rebasing and staging.

An intelligent ORM analysis and optimization platform for Django that detects N+1 queries, duplicate queries, and slow queries.

A cross-platform tool that remaps keys context-awarely, supporting systemwide or per-app shortcuts, mouse buttons, virtual keys, and external control via keymapperctl.

CoalLedger is a docs-health checking suite for AI coding agents — the documentation counterpart to CoalMine's code canaries. Seven canaries flag wrong, incomplete, stale, contradictory, broken, unreadable and (optionally) leaked documentation, with a bundled zero-dependency CommonMark+GFM AST engine, context-judged severity and choice-gated fixes.

Web-Check is an open-source, self-hostable OSINT dashboard for analysing any website. It gathers IP, DNS, SSL, headers, cookies, crawl rules, ports, traceroute, server location, redirects, trackers, performance and carbon footprint data.

ECC is an agent harness operating system that provides a coordinated engineering system and toolbox for AI agents, enabling structured workflows like planning, testing, and reviewing.

Ambition is an experimental, ECS-native 2D platformer engine built on Rust and Bevy. It features a headless-testable architecture, agent-native authoring tools for sprites and music, and a data-driven design focused on long-term elegance and reusability.
