WebContainers
A browser-native Node.js-compatible runtime environment developed by StackBlitz. It uses Service Workers and a WebAssembly file system layer to emulate full Node.js module resolution and I/O behavior inside the browser, without requiring server-side containers.
Core Facts
Bolt.new is built on WebContainers technology, enabling a full Node.js environment to run inside the browser.
WebContainers is a sandbox technology capable of running a complete Node.js environment inside the browser.
Bolt.new is developed by the StackBlitz team, and its core technology is based on WebContainers—a technology that enables a complete Node.js development environment to run in the browser.
Timeline (last 90 days)
The core trick of WebContainers is to use a Service Worker to intercept network requests, combined with a WASM-compiled file system layer, to simulate Node.js module resolution and I/O behavior.
The WebContainers approach has been used in production by products such as bolt.new under StackBlitz.
Running a real terminal environment inside a browser typically relies on WebAssembly or Linux-based container technologies, such as WebContainers or Xterm.js paired with a backend sandbox.
