# FreeOxide: open-source Rust projects, held to the metal

> Open-source Rust, built by one person and held to the metal. Every project gets real tests and real audits before it ships. Start with gpui-starter.

## What this is

Open-source Rust, held to the metal. FreeOxide is where one person publishes small, finished Rust developer tools. Nothing here is sold or metered, and nothing ships until it clears the standard below.

## How every project is built

- **Architecture by experience**: Folder structure, module boundaries, and layout decided upfront from what I know works.
- **Five AI audit passes**: Same model, different sessions. Each finds things the last missed. After five, the returns thin out.
- **Five testing rounds**: Same approach. AI writes tests, I review, next session catches what the previous one missed.
- **Idiomatic & documented**: Clippy-clean with sensible defaults. If something needs a comment to use safely, it gets one.
- **Open by default**: MIT / Apache-2.0, readable git history, no hidden dependencies.

Audit passes per project: 4 to 5. AI edge-case rounds: 5. Coverage floor: above 90%. Licensing: fully open, MIT / Apache-2.0.

## Projects

- **gpui-starter** (shipped): A batteries-included starting point for native GPUI apps. The scaffold I wanted on day one. Source: https://github.com/hmziqrs/gpui-starter.
- **gpui-query** (shipped): Reactive async queries for GPUI apps. Fetch, cache, and invalidate without leaving the render tree. Source: https://github.com/hmziqrs/gpui-query.
- **tunnel** (shipped): Serves a local directory over an ephemeral Cloudflare Quick Tunnel. You get a public HTTPS URL in a few seconds without a Cloudflare account or any DNS setup. Source: https://github.com/freeoxide/tunnel.
- **wake** (shipped): Keeps a machine awake for as long as you ask. When the OS refuses the lock it says so instead of failing quietly, and ow doctor prints what each backend can actually guarantee. Source: https://github.com/freeoxide/wake.
- **vps-harden** (in progress): Harden a fresh VPS with one auditable command. Sensible, reversible, opinionated defaults. Source: not public yet.
- **agent-config** (planned): A native desktop app to see and manage your AI agents' configuration and usage. Built on gpui-starter. Source: not public yet.
