A Linux-like kernel in a browser tab - deep dive in the BrowserPod architecture
BrowserPod is an innovative in-browser sandbox that utilizes WebAssembly to create a Linux-like kernel. This architecture allows it to run full stack applications entirely within the browser. The article explores the design, capabilities, and limitations of BrowserPod, focusing on its core functions and subsystems.
- ▪BrowserPod runs completely client-side and is powered by WebAssembly.
- ▪It features a WebAssembly-native kernel designed to be compatible with applications originally made for Linux.
