Prerequisites

A compatible editor

Jetro is a VS Code extension. It runs in any editor that supports the VS Code extension API. Here are the three we recommend.

Antigravity (recommended)

A VS Code fork built for AI agents. It ships with deep agent integration and a few quality-of-life tweaks that make working with Jetro smoother. Pair it with Claude Code for the best experience. Free to use.

Cursor

An AI-native editor with built-in coding agents. Supports Claude, GPT, Gemini, and DeepSeek out of the box. If you already have a Cursor subscription, you get an AI agent included, so you may not need a separate AI subscription.

VS Code

The classic. Millions of developers use it daily, and it works great with Jetro. The best way to use Jetro inside VS Code is with the Claude Code extension as your agent.

Tip

Jetro works best inside Antigravity with Claude Code. But it runs in any VS Code-compatible editor.

Python 3.9+

Optional but recommended. Jetro uses Python for live refresh scripts and code execution. If you want real-time data updates on your canvases, you will need Python installed.

Check your version:

python3 --version

Node.js 18+

Required if you are using the Claude Code CLI as your AI agent. Not needed if your editor has a built-in agent (like Cursor).

Check your version:

node --version

An AI agent

Jetro needs a coding agent to do the heavy lifting. The agent talks to Jetro’s tools, fetches data, builds your canvas. Here are the recommended setups:

Claude Code extension (recommended for VS Code and Antigravity)

Claude Code is an extension by Anthropic that turns Claude into a coding agent inside your editor. It works in VS Code, Antigravity, and Cursor. This is our recommended way to use Jetro.

To install it:

Open the Extensions sidebar in your editor (Ctrl+Shift+X / Cmd+Shift+X).
Search for “Claude Code” and click Install.
You will need either a Claude Pro or Claude Max subscription.

Once installed, Claude Code automatically discovers Jetro’s tools through the MCP config. No extra setup needed.

Cursor’s built-in agents

If you use Cursor, it ships with built-in agents that support Claude, GPT, Gemini, and DeepSeek. A Cursor Pro or Business subscription covers this. Jetro’s tools integrate automatically with these agents too.

Other agents

Any MCP-compatible agent will work with Jetro. This includes Cline, Windsurf’s built-in agent, and others. As long as the agent can call MCP tools, Jetro will plug in.

You need at least one working agent to use Jetro’s full capabilities. Without an agent, you can still browse data and build canvases manually.

Docker (for app deployment)

Optional. Required only if you want to deploy apps locally. Jetro uses Docker to run your deployed apps in isolated containers with public URLs.

Download at docker.com

Check if it’s installed:

docker --version

Not needed for Jetro Cloud deployment (coming soon) or for any other Jetro feature.

Internet connection

Jetro fetches live market data, financial statements, and other information from remote APIs. You need an active internet connection for these features to work. Offline access is limited to cached data and local files.
