Install and first run

Terax ships as a signed desktop bundle. Download the installer for your platform from the Releases page. Terax auto-updates from there.

macOS

Two separate .dmg builds - one for Apple Silicon (aarch64), one for Intel (x86_64). Pick the one that matches your hardware on the Releases page, drag Terax to /Applications, and launch.

Linux

Arch / AUR: yay -S terax-bin (or paru, etc.). Tracks the latest release.
Debian / Ubuntu: install the .deb from Releases. Depends on libwebkit2gtk-4.1-0 and libgtk-3-0.
Fedora / RHEL: install the .rpm. Depends on webkit2gtk4.1 and gtk3.
AppImage: needs FUSE. If FUSE is missing, run ./Terax_*.AppImage --appimage-extract-and-run.
On Wayland with rendering glitches, set WEBKIT_DISABLE_DMABUF_RENDERER=1. The .deb / .rpm packages link against the system GTK stack and tend to be smoother than the AppImage.

Windows

NSIS installer in currentUser mode (no admin required). WebView2 is bootstrapped offline.

On first launch Windows may show "Windows protected your PC" because Terax is not code-signed yet. Click More info then Run anyway.

Default shell detection on Windows: pwsh.exe (PowerShell 7+) -> powershell.exe (Windows PowerShell 5.1) -> cmd.exe. WSL distros are first-class workspaces, not a wrapped subprocess. See Workspaces.

Connect your first AI provider

Terax is BYOK. Pick any supported provider and paste your key in Settings.

Open Settings -> Models (Cmd+, then choose Models, or click the gear in the sidebar).
Pick a provider (OpenAI, Anthropic, Google, Groq, xAI, Cerebras, OpenRouter, DeepSeek, Mistral, or any OpenAI-compatible endpoint).
Paste your API key.

Keys are written to the OS keychain via the keyring crate (service terax-ai). They never touch disk, localStorage, or the settings file.

Local and offline

You can run entirely offline against LM Studio, MLX, or Ollama. Point Terax at the endpoint URL in Settings -> Models. No key required, just a model id at runtime.

Build from source

Prerequisites: Rust (stable), Node 20+, pnpm, and the Tauri prerequisites for your platform.

pnpm install
pnpm tauri dev          # development
pnpm tauri build        # production bundle
