About BrowserPod

BrowserPod is built by Leaning Technologies, a WebAssembly engineering company founded in 2015. We build runtimes that let desktop and server-based software run inside the browser, on the user's own machine rather than on a server.

BrowserPod boots full environments, such as Node.js, Python and Rust, in a browser tab, with no server doing the work behind it. Our other projects include CheerpJ, which runs Java in the browser, and WebVM, a Linux virtual machine that runs entirely client-side. Code runs close to the user, isolated from the host machine, and at a speed that is close to native.
