Terax

Lightweight, terminal-first dev workspace with first-class Claude Code integration.

---

Terax is a lightweight, open-source, terminal-first dev workspace built on Tauri 2 + Rust and React 19. A native PTY backend with a WebGL renderer, a code editor, file explorer, source control with a git graph, and a web preview pane, plus first-class Claude Code integration: run Claude Code in the terminal with native notifications and activity tracking. About 7-8 MB on disk. No telemetry. No account.

Features

Terminal

• xterm.js with WebGL renderer, multi-tab with background streaming
• 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.)
• 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

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

Claude Code integration

Terax is a host for Claude Code in the terminal. It makes no model calls of its own; it observes the agent (via Claude Code hooks and the session transcript) and feeds the focused pane.

• Detects when Claude Code is running in the terminal, with per-tab activity indicators (working / waiting / failed) and native + in-app notifications when it needs input, finishes, or a tool fails
• Session switcher: see every Claude Code session, jump to a running one, or resume a dead one in a click
• Send to Claude: hand a file (from the explorer) or an editor selection to the focused agent as an @path#L10-20 reference, without retyping paths
• Edit inbox: each tab shows the files the agent just changed and opens them in the editor with one click
• Plan panel: the agent's live to-do checklist in the sidebar
• Per-pane HUD: context-window usage, model, tokens, and an estimated cost, read-only from the transcript (no changes to your Claude config)
• Agent dashboard: one mission-control view of every running agent across panes
• Quick-prompt palette: fuzzy palette of reusable prompts and your .claude slash-commands, typed straight into the pane

These features cost nothing when no agent is running. Enable the hooks from the notification bell.

Install

Build from source — see Build from source below.

Windows notes

• On first launch Windows shows "Windows protected your PC" because Terax isn't code-signed yet (will be fixed soon). 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.
• 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.
