Terax

Lightweight Terminal-first AI-native dev workspace.

Website Docs Website's source code

Terax is a lightweight open-source terminal-first AI-native development environment (ADE) built on Tauri 2 + Rust and React 19. A native PTY backend with a WebGL renderer, an agentic AI side-panel that runs against your own keys or fully local models, plus a code editor, file explorer, source control with a git graph, and a web preview pane built in. About 7-8 MB on disk. No telemetry. No account.

Over the past few months, most of my development time went into building Zephium (opens in a new tab), a new browser-native work environment rebuilt for humans and agents.

Terax is now returning to active development. A major v0.9.0 update is already in progress, with some substantial architectural changes, including moving from xterm.js to libghostty + WebGPU.

More updates soon.
