Run AI code securely on any device
Sandboxed server runtimes that run directly in the browser. Free for 1,000 hours p/m and $0.01 per extra hour.
Built by Leaning Technologies, the tech company trusted by leading organisations worldwide.
Browser-based runtimes for secure code execution
Isolate AI slop and malicious code
Agentic code can't escape the browser's sandbox to access local files, or unauthorised network calls.
A boot time barely measurable in milliseconds.
Sandboxes launch instantly in-browser, eliminating cloud-based roundtrip latency.
Cut sandbox costs by up to 94%
BrowserPod is free for up to 1,000 hours p/m and $0.01 per additional hour.
Data doesn't leave the device
Sandboxes boot in the browser directly, meaning files are secure on device.
Instant, interactive demos
Share your real app instantly via a secure private link with just a few lines of code.
A real filesystem, in the browser
Sandboxed POSIX-style filesystem for you to execute agentic code.
Expansive dev toolchain
Install packages from npm, clone repos with git, manage files and more with bash.
Unlimited concurrent sandboxes
BrowserPod works on-device, meaning you can run an infinite sandboxes at the same time. And without incurring additional cloud costs.
A universal execution layer for the browser.
Node.js is fully supported today, with Python, Ruby, Go, and Rust coming soon.

import { BrowserPod } from "@leaningtech/browserpod";
// Initialize a Pod.
const pod = await BrowserPod.boot({ apiKey: "your-api-key" });
// Create a Terminal
const terminal = await pod.createDefaultTerminal(
document.getElementById("console"),
);
// Define the payload
const script = `
console.log("Payload running on Node.js:", process.version);
`;
// Write the script into the Pod's filesystem
const scriptFile = await pod.createFile("/script.js", "utf-8");
await scriptFile.write(script);
await scriptFile.close();
// Run the script
await pod.run("node", ["script.js"], { terminal });See how BrowserPod stacks up.
In-browser sandboxes mean zero infrastructure costs and unlimited concurrency.
