Hopx lets you spin up fully isolated Linux micro-VMs in ~100 ms — perfect for running AI agents, notebooks, or untrusted code safely at scale. Each sandbox runs in its own Firecracker microVM, with full state persistence, SDKs for Python, JS, Go, and more. No cold-start lag. No runtime limits. Just raw performance and security.

🚀 Update: We just released the MCP Server for Hopx!

You can now connect Hopx sandboxes directly into your MCP-compatible IDEs and agent frameworks.

🔗 https://github.com/hopx-ai/mcp

Simply add the Hopx MCP server to your config:

{
  "mcpServers": {
    "hopx-sandbox": {
      "command": "uvx",
      "args": ["hopx-mcp"],
      "env": {
        "HOPX_API_KEY": "your-api-key-here"
      }
    }
  }
}

Build, test, and run your agents in fully isolated microVMs — right from your IDE.

Congrats on the launch! A couple of things I was curious about:
Is the main value prop the speed of spinning up new environments?
And how would this fit into an existing cloud setup - does it run alongside AWS/GCP, or replace part of it?

The main prop is the combination between the speed, vm-level isolation and easy of use.

Here a quick example how to spin-up a sandbox in ms, run your code, kill the sandbox. Very useful when developing AI Agents, to run untrusted code in isolation. But you can really spin up anything, from self-hosted LLMs, to ETL jobs, mcp servers, full APIs, apps etc.

import { Sandbox } from '@hopx-ai/sdk';

const sandbox = await Sandbox.create({
  template: 'code-interpreter',
  apiKey: process.env.HOPX_API_KEY
});

// Execute Python code
const result = await sandbox.runCode(`
import sys
print(f"Python {sys.version}")
print("Hello from HopX!")
`);

console.log(result.stdout);
// Output: Python 3.11...
//         Hello from HopX!

await sandbox.kill();

Amazing work and congratulations on the launch! Do you mind sharing how hopx compares to E2B?

Also wondering about this! It looks like they have the exact same per-second costs, but Hopx has more lenient rate limits?

Great niche. Can ChatGPT or Gemini be integrated?
