Terax Ai
Terminal-first AI dev workspace with Vim, agents, and live web preview
Terax is the fastest, most private way we've found to get AI agents and Vim in one terminal-first workspace. It's not a full IDE—debugging and heavy refactoring are absent—but for 7 MB and no telemetry, it's a daily driver worth switching for. If you live in the terminal and value speed and privacy over IDE bloat, give it a try; if you need a debugger or team collaboration, stick with VS Code or Cursor.

Skip Terax if you rely on a full IDE debugger, need team collaboration or cloud sync, or prefer a mouse-driven, GUI-heavy workflow over a keyboard-first terminal experience.
Cloud AI models (OpenAI, Anthropic, etc.) require your own API key, and usage is billed by the provider—costs scale with your token usage.
Terax is free and open source, so cost is zero for the app itself. However, you'll pay for AI usage through your chosen provider (BYOK). This makes it ideal for solo developers who already use OpenAI or Anthropic APIs and want a lightweight terminal. Compared to Cursor or GitHub Copilot (which charge monthly subscriptions), Terax's BYOK model can be cheaper if you're a low-volume user. For teams needing collaboration, it's not a fit.
In short
Terax Ai — Terminal-first AI dev workspace with Vim, agents, and live web preview. Best for Vim users who want AI autocomplete and agents in a keyboard-first editor, Privacy-conscious developers who prefer local models like Ollama or LM Studio, Web developers needing live preview of Vite, Next, or Astro apps. Free to use.

About Terax Ai
Terax is a free, open-source, terminal-first AI-native dev workspace that packs a terminal, a Vim-mode editor, AI agents, and a live web preview into a 7 MB desktop app that cold-starts in roughly 300 ms. Built on Tauri 2 and React 19, it skips the Electron bloat and runs offline-capable: bring your own API key for cloud models from OpenAI, Anthropic, Google, Groq, Cerebras, xAI, or Mistral, or go fully local with LM Studio, MLX, or Ollama—your code never leaves your disk if you choose local. It targets developers who live in the command line and want AI assistance without a heavy IDE, and it demands zero account, zero telemetry, and zero setup beyond a download. At the core is a WebGL-rendered xterm.js terminal (with GPU block-mode rendering and multi-tab support), a file explorer with Catppuccin icons, and a built-in editor with real Vim mode—motions, registers, marks, and dotfile support—plus context-aware AI autocomplete and sub-millisecond keystroke latency. Version control is built in: hunk-level staging, one-shortcut commits, and a commit graph that makes branches and merges clear. The web preview auto-detects dev servers like Vite, Next, and Astro and opens them as a tab right next to your editor. AI is woven in without getting in the way. Agents read files, run commands, and propose changes as reviewable AI Edit Diffs; you approve each diff before it touches your project. A TERAX.md file in your repo gives agents persistent project memory, and snippets and skills turn repeatable workflows into callable commands. Voice input via Whisper or your provider lets you dictate to your agents while you code. The latest releases (v0.8.0 is current) added a command palette, GPU block-mode terminal, persisted tab groups (spaces), media viewers, and Nix support. Terax positions itself as a lightweight, keyboard-first alternative to full IDEs like VS Code or Cursor for developers who want a fast, private, terminal-centric environment. It's not a feature-for-feature copy—you'll give up a full debugger UI and integrated refactoring tools—but in exchange you get a 7 MB, 300 ms, no-telemetry workspace that respects your dotfiles and your privacy.
Behind the Verdict
Terax is a breath of fresh air for developers who've grown tired of Electron-based IDEs gobbling up RAM and phoning home. It's a genuine terminal-first workspace: the terminal is the star, and the editor, file explorer, source control, and web preview all orbit around it. The WebGL-rendered xterm.js terminal is silky, and the GPU block-mode terminal (Warp-style) is a standout—it makes command blocks feel native and fast. The Vim mode is real: motions, registers, marks, and dotfile support mean you can bring your entire muscle memory and config. AI is integrated thoughtfully. Agents can read files, run commands, and propose changes as AI Edit Diffs that you review before they land. The TERAX.md file gives agents persistent project memory, and snippets/skills let you turn repeatable workflows into callable commands. Voice input via Whisper is a nice touch for dictating while you code. The bring-your-own-key model means you control your costs and data; local models via LM Studio, MLX, or Ollama mean you can go fully offline. Strengths: blazing fast (7 MB, 300 ms cold start), zero telemetry, no account required, open source (Apache-2.0), real Vim mode, and a surprisingly complete toolset for a pre-1.0 app. The recent v0.8.0 release added a command palette, GPU block-mode terminal, spaces (persisted tab groups), media viewers, and Nix support—showing active development. Weaknesses: it's pre-1.0 (v0.8.0), so breaking changes are possible. The editor is CodeMirror-based, so you won't get the full IDE feature set—no debugger UI, no integrated refactoring tools. Collaboration is absent: no cloud sync, no team features. You'll need to bring your own API keys for cloud AI, and local model setup might be intimidating for some. Where it fits: Vim users, terminal lovers, privacy-conscious developers, and open-source enthusiasts who want a fast, keyboard-centric AI assistant. Where it doesn't: teams needing hosted collaboration, users who rely on a GUI debugger, or beginners who prefer a mouse-driven, feature-rich IDE. Overall, Terax is a impressive example of what a focused, minimalist dev tool can be. It's not trying to replace everything—it's trying to give you a fast, private terminal-first space to code with AI assistance, and it succeeds admirably.

Real-world workflow fit
Concrete scenarios for the personas Terax Ai actually fits — and what changes day-one when you adopt it.
Clone a repo, open Terax, use Vim motions to navigate, run `npm run dev` in the terminal, and see the live preview in a tab. Ask an AI agent to refactor a function, review the AI Edit Diff, and approve it.
Outcome: Complete a coding session entirely within the terminal-first workspace, with AI assistance and live preview, without opening a separate browser or IDE.
Use Ollama for local AI, configure Terax to use it, and work on a sensitive codebase fully offline. Stage and commit changes using the built-in git graph.
Outcome: Get AI autocomplete and agent assistance without sending code to a cloud provider, keeping data on disk.
Use Cases
- Edit code with Vim motions and get AI autocomplete suggestions inline.
- Run terminal commands and see live web preview of your dev server.
- Stage git hunks and view commit graph without leaving the editor.
- Ask AI agents to explore codebase, run commands, and propose changes.
- Customize every pixel with themes and background images.
- Use voice input to interact with agents while keeping hands on keyboard.
Models Under the Hood

Limitations
- Terax is pre-1.0 software (currently v0.8.0), so breaking changes may occur in minor releases.
- The editor is based on CodeMirror 6 and lacks advanced IDE features like a debugger UI or integrated refactoring tools.
- AI features require either a bring-your-own-key for cloud models or local setup via LM Studio, MLX, or Ollama, which may be complex for some users.
- No hosted service, account, or telemetry.
- Collaborative features are absent—there's no cloud sync or multi-user support.

Where the pricing makes sense
The company stage and team size where Terax Ai's pricing actually pencils out — and where peers do it cheaper.
Terax is free and open source, so cost is zero for the app itself. However, you'll pay for AI usage through your chosen provider (BYOK). This makes it ideal for solo developers who already use OpenAI or Anthropic APIs and want a lightweight terminal. Compared to Cursor or GitHub Copilot (which charge monthly subscriptions), Terax's BYOK model can be cheaper if you're a low-volume user. For teams needing collaboration, it's not a fit.
Setup time & first value
How long it actually takes to get something useful out of Terax Ai — broken out by persona, not the marketing-page minute.
For most users, setup takes under 5 minutes: download the app, launch it, and configure your first AI provider (paste an API key or point to a local model like Ollama). Vim users can import their dotfiles immediately. The first value comes from the terminal and editor core, which work instantly with zero configuration.
Switching to or from Terax Ai
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From VS Code: Install Terax, configure your Vim dotfiles, and open your project folder; keyboard shortcuts are limited but Vim muscle memory transfers directly. You won't need to migrate extensions—most are built-in.
- ↗To VS Code: Your project files remain unchanged; only Terax-specific config like TERAX.md and custom themes would need to be moved manually.
