BrowserPod is a universal execution layer for browser-based compute, providing a sandboxed runtime API for running full-stack workloads directly inside the browser.

Run Node.js projects unmodified. No installation or per-session cloud sandboxes required. Execution stays inside the browser, reducing latency, infrastructure overhead, and data exposure.

What is BrowserPod?

BrowserPod runs fully compiled language runtimes via WebAssembly inside a browser tab, preserving high fidelity with native execution. Each Pod is an isolated instance with:

• Real language runtimes running client-side at near-native speed (Node.js available now, Python, Ruby, Go, and Linux-class workloads planned)
• A block-based streaming virtual filesystem with familiar file and directory behavior
• Portals that securely expose services running inside a Pod through controlled, shareable URLs
• Browser sandbox security—isolated from the user's OS

Everything runs client-side within the browser. Users don’t need to install anything. No per-session cloud sandbox provisioning is required.

Use Cases

• Live product demos: Ship demos that run real backend logic without infrastructure
• Agentic coding and AI-generated code execution: Run untrusted code generated by AI agents in a contained environment
• Interactive tutorials and live documentation: Let users run actual servers and see responses while learning
• Web-based IDEs: run package installs, dev servers, and tools in-browser
• Browser-based "server" functions: Run tasks that typically need cloud provisioning, like HTTP requests or API calls, entirely client-side
