Terax is a lightweight open-source terminal (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.

Features

Terminal

• xterm.js with WebGL renderer, multi-tab with background streaming
• GPU-accelerated block-based terminal with editor-like command input
• Native PTY backend via portable-pty (zsh, bash, pwsh, fish, cmd)
• Split panels (horizontal and vertical)
• Inline search, link detection, true-color
• Per-tab workspace environments on Windows (Local, or any installed WSL distro)

Code editor

• CodeMirror 6 (supports all popular languages - TS/JS, Rust, Python, Go, C/C++, Java, HTML/CSS, JSON, Markdown, etc.)
• Inline AI autocomplete with local model support
• AI edit diffs, accept or reject hunk by hunk
• Vim mode
• Ten built-in editor themes: Atom One, Aura, Copilot, GitHub Dark / Light, Gruvbox Dark, Nord, Tokyo Night, Xcode Dark / Light

Source control

• Stage / unstage hunks, commit (Cmd+Enter / Ctrl+Enter), push with upstream awareness
• Branch display including detached HEAD state
• Git history pane with a real commit graph (lane rendering for merges and branches)
• Commit search and filter, click through to the remote commit page

File explorer

• Catppuccin icon theme
• Fuzzy search, keyboard navigation, inline rename, context actions
• Attach files and selections directly to the AI side-panel

Web preview

• Auto-detects local dev servers and opens them in a preview tab
• External URL preview via a native child webview

Themes and customization

• Custom themes built in-app, switch between bundled presets and your own
• Create your own themes, share them or import from the community
• Background images with adjustable opacity and blur
• Editor theme is independent from the app theme

AI

• BYOK providers: OpenAI, Anthropic, Google (Gemini), Groq, xAI (Grok), Cerebras, OpenRouter, DeepSeek, Mistral, plus any OpenAI-compatible endpoint
• Local / offline: LM Studio, MLX, Ollama
• Agentic workflow: plans, sub-agents, project memory via TERAX.md, file read / write / edit / multi-edit / grep / glob, bash with approval gating, background processes
• Composer: snippets via #handle, files via @path, slash commands, voice input, attach-to-agent from explorer or selection
• Custom agents with their own system prompt and tool subset
• Plan mode for multi-step work, generates and confirms before doing

Install

Latest installers are on the Releases page. Terax auto-updates from there.

Windows notes

• On first launch Windows shows "Windows protected your PC" because Terax isn't code-signed yet. Click More info then Run anyway.
• Default shell detection: pwsh.exe (PowerShell 7+) -> powershell.exe (Windows PowerShell 5.1) -> cmd.exe.
• WSL is a first-class workspace environment, not a wrapped subprocess.

Linux notes

• Arch / AUR: yay -S terax-bin (or paru, etc.). Tracks the latest release.
• NixOS / Nix: use the official flake — nix profile install github:crynta/terax-ai (non-NixOS), or import the flake and add inputs.terax.packages.${pkgs.system}.terax to environment.systemPackages (NixOS). The nixosModules.terax output is also available for a simpler setup.
• AppImage: needs FUSE. Without it: ./Terax_*.AppImage --appimage-extract-and-run. On Wayland with rendering glitches, try WEBKIT_DISABLE_DMABUF_RENDERER=1. Otherwise the .deb / .rpm packages link against the system GTK stack and tend to be smoother.

Configure AI

1. Open Settings -> AI.
2. Pick a provider and paste your API key. For local inference, point Terax at your LM Studio / MLX / Ollama endpoint.
3. Keys are written to the OS keychain via keyring. They never touch disk or localStorage.

Build from source

Prerequisites - Rust (stable), https://rustup.rs - Node 20+ and pnpm - Tauri prerequisites for your platform, https://tauri.app/start/prerequisites/
