Map what you build

Architecture decisions rot when they live only in people's heads. c4-board gives you a visual C4 modelling board built on Tauri and Astro. tech-radar-web tracks your technology choices as a living document. tech-radar-tui brings ADR authoring and radar management to the terminal — keyboard-driven, written in Rust.

Raise the bar

elysia-spectral enforces OpenAPI quality at the Elysia framework level, catching contract drift before it ships. planetnik makes large TypeScript codebases navigable through static analysis. crumbs-css brings React Native's styling ergonomics to the browser with a vanilla-extract-shaped API.
