Terax AI

Terax is a desktop development environment built around a terminal, with an AI agent panel, code editor, file explorer, source control, and web preview in one app. It is built with Tauri 2, Rust, and React 19, is roughly 7 to 8 MB on disk, and runs without telemetry or an account.

The terminal uses a native PTY backend with a GPU-accelerated renderer, multiple tabs, split panels, and block-based command input, and it supports zsh, bash, PowerShell, fish, and cmd, with WSL distributions as first-class environments on Windows. The editor is built on CodeMirror 6 with inline AI autocomplete, hunk-by-hunk acceptance of AI edits, optional language server support, and a Vim mode. Source control covers hunk staging, commits, pushes, and a git history pane with a commit graph, and the preview pane detects local dev servers and opens them in a tab.

The AI side panel runs against your own API keys or local models, with keys held in the OS keychain. It can plan multi-step work, run sub-agents, keep project memory in a Markdown file, read, write, and search files, and run shell commands behind approval prompts. It can also start Claude Code in a terminal, read its output, and send it follow-up work. Custom agents can carry their own system prompt and tool subset.
