Terax Ai
Terax is a terminal-first AI-native dev workspace with Vim editing, agentic AI coding agents, and live web preview in a 7 MB app
The cleanest execution of the terminal-first AI workspace idea we've seen — agents, Vim, Git, and live preview in an Apache-2.0 app with no account and no telemetry. It earns the recommendation for keyboard-first developers who want AI in the shell without dragging a full IDE along. The tradeoffs are real and named in its own docs: no debugger UI, no refactoring tools, no hosted team collaboration.

Skip Terax if your team needs shared cloud workspaces, or if you depend on a graphical debugger and refactoring tooling rather than keyboard-first editing.
AI features are bring-your-own-key, so your OpenAI, Anthropic, or other provider bill is separate from the app itself.
Terax is released under Apache-2.0 at no cost, with source, builds, and SHA256 checksums published on GitHub. The real spend is your own model bill: cloud providers you connect via API key are metered by them, while LM Studio, MLX, and Ollama cost nothing beyond your hardware. That puts it well below paid AI editors that bundle a subscription, and alongside other open-source terminal tools.
In short
Terax Ai — Terax is a terminal-first AI-native dev workspace with Vim editing, agentic AI coding agents, and live web preview in a 7 MB app. Best for Vim users who want AI autocomplete and agents inside a keyboard-first editor, Privacy-conscious developers who prefer local models via LM Studio, MLX, or Ollama, Web developers who want live Vite, Next, or Astro preview in the same pane as their code.

About Terax Ai
Terax is a terminal-first, AI-native dev workspace for developers who live in the shell. The desktop app — now at v0.8.6 — bundles a WebGL-rendered xterm.js terminal, a CodeMirror editor with real Vim mode, a Git client with hunk-level staging and a commit graph, agentic AI agents, and a live web preview into a Tauri build that lands under 10 MB on disk with a ~300 ms cold start. There's no Electron tax, no account, and no telemetry; it ships Apache-2.0 on GitHub. The AI workflow is the draw. Multi-agents and sub-agents browse files, run commands, and propose changes, but every edit lands in a reviewable AI Edit Diff before it touches disk. TERAX.md gives each repo persistent memory and per-project config versioned with your source, while snippets and skills turn repeatable workflows into agent-callable commands. BYOK covers OpenAI, Anthropic, Google, Groq, Cerebras, xAI, and Mistral, or you can run fully offline through LM Studio, MLX, or Ollama. Source control is built in: hunk-level stage/unstage/discard, Cmd+Enter commits, push with upstream awareness, and a commit graph showing branches, merges, and refs. The web preview auto-detects dev servers like Vite, Next, and Astro and opens them as a tab beside your editor, and v0.8.0 added a fuzzy command palette plus media and document viewers for images, audio, video, PDF, and Markdown. Terax sits apart from full IDEs like VS Code or Cursor: you give up a visual debugger and deep refactoring tooling, and there's no hosted team collaboration. What you get instead is a tiny, dotfile-respecting, login-free workspace that assumes a terminal, a keyboard, and your own API key.
Behind the Verdict
Terax lands in a strange gap: heavier than a bare terminal, far lighter than Cursor or a VS Code + Copilot stack. If your day is tmux, ripgrep, and a dotfiles repo, the pitch is easy to like. We'd reach for this when the workflow is shell-first and the browser tab count is the enemy. Auto-detecting a Vite or Next dev server and dropping the preview beside your editor removes one of the most common alt-tab loops. The AI Edit Diff gate is the feature that matters most day to day — agents proposing changes is table stakes in 2026, but seeing every diff before it writes to disk is what makes it usable in a real repo. Where it bites: no visual debugger and no heavy refactoring tooling, so anyone doing step-through debugging or large cross-file refactors will keep a second editor open. There's also nothing for teams — no shared workspaces, no cloud sync, no hosted collaboration. That's a deliberate trade, not a bug, but it rules Terax out for orgs that need shared state. Against alternatives, the honest comparison is a VS Code + Copilot setup or Cursor. Both give you a debugger, extensions, and collaboration; both assume an account and a much larger install. Terax assumes a terminal, a keyboard, and your API key. If you want local models via LM Studio, MLX, or Ollama with no cloud round-trip, that gap widens. The pricing question is simple: v0.8.6 is a free, Apache-2.0 download from GitHub with no signup. You pay your model provider, not Terax. For a solo dev or small team already comfortable in Vim, the trial cost is whatever an afternoon of reading the changelog costs. One caveat worth flagging: this is a fast-moving preview build. v0.7.0 through v0.8.6 shipped in under a month, which means features land quickly but edges are still being sanded. Pin a version you

Real-world workflow fit
Concrete scenarios for the personas Terax Ai actually fits — and what changes day-one when you adopt it.
Clones a Rust repo, opens the built-in editor with dotfiles loaded, and asks an agent to trace an error through the codebase. The agent reads files, runs cargo commands, and proposes an edit as an AI Edit Diff.
Outcome: Reviews the diff inline, approves it, commits with Cmd+Enter after staging the hunk in the Git panel — all without leaving the terminal tab.
Runs a Vite dev server locally and points Terax at Ollama for autocomplete and agent help. Declines to configure any cloud provider key.
Outcome: Gets AI suggestions and agent edits with code that never leaves the machine, and the web preview auto-opens the Vite URL as a tab beside the editor.
Uses the /claude-code slash command and the agent notification router added in v0.7.3 to run the built-in agent alongside a terminal-based coding agent.
Outcome: Receives all agent events through a single bell, and the live filesystem watcher keeps the explorer tree and open editors in sync as files change.
Use Cases
- Edit code with Vim motions and get AI autocomplete suggestions inline.
- Run terminal commands and see a live web preview of your dev server in an adjacent tab.
- Stage git hunks and read history through a commit graph without leaving the editor.
- Ask AI agents to explore a codebase, run commands, and propose changes as reviewable diffs.
- Point Terax at LM Studio, MLX, or Ollama to get AI help with code that stays on disk.
- Use voice input to interact with agents while keeping your hands on the keyboard.
- Build custom themes in-app and export them as shareable JSON.
- Track plans, tasks, and TODOs in-app so agents pick up where you left off.
Models Under the Hood

Limitations
- Terax is pre-1.0 at v0.8.6, and its own changelog warns that pre-1.0 minor releases may include breaking changes.
- It is not a full IDE: it has no debugger UI or refactoring tools, only a CodeMirror 6 editor with Vim mode and inline AI diffs.
- AI features require either bring-your-own-keys for cloud providers (OpenAI, Anthropic, Google, Groq, Cerebras, xAI, Mistral) or a local setup via LM Studio, MLX, or Ollama.
- It is not a hosted service and has no account, backend, or telemetry.

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 released under Apache-2.0 at no cost, with source, builds, and SHA256 checksums published on GitHub. The real spend is your own model bill: cloud providers you connect via API key are metered by them, while LM Studio, MLX, and Ollama cost nothing beyond your hardware. That puts it well below paid AI editors that bundle a subscription, and alongside other open-source terminal tools.
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.
Install to first value is quick: download the platform build (macOS Apple Silicon/Intel, Linux AppImage/.deb/.rpm/AUR, or Windows NSIS), run it, and connect a provider. Configuring a cloud key is minutes; a local model via LM Studio, MLX, or Ollama adds a bit more for model download and endpoint setup. No account or signup step stands in the way.
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 + terminal: keep your shell workflow, open the project folder in Terax, and paste your API key into provider settings; the Vim mode accepts your existing dotfiles.
- →From a hosted AI editor: move your repository locally and bring your own key for the same provider, or point Terax at LM Studio, MLX, or Ollama for offline use.
- →From tmux + nvim: reuse your Vim motions and registers in the built-in editor, and rebuild repeatable flows as Terax snippets or skills agents can call.
- ↗To VS Code or Cursor: your repository and TERAX.md file travel with the project; you will re-add editor extensions and debugger config that Terax does not provide.
- ↗To Neovim + tmux: your dotfiles and Vim muscle memory carry over; you lose the built-in Git graph, AI Edit Diffs, and web preview panes.
