Run anything
in the browser.
Browser-based compute infrastructure for the AI era.
About Leaning Technologies
We're turning the browser into a universal compute layer for the next generation of web-based experiences.
We're experts in WebAssembly. We push the boundaries of what's possible in the browser, building compute infrastructure and dev tools that can run anything in the browser. Whether it's full-stack environments like Node.js, Python and Rails, or compiled languages like C++, Java and Go. We make it run in the browser, at near-native speed, fully isolated and next to the user.
