Wterm – Terminal Emulator for the Web

Wterm is a web-based terminal emulator that renders directly to the DOM, providing native browser features like text selection, copy/paste, and accessibility without extra implementation. Built with a Zig core compiled to WebAssembly for near-native performance, it supports advanced terminal features including VT100/VT220/xterm escape sequences, 24-bit color, Unicode support, and multiple themes. The lightweight implementation achieves these capabilities in a compact ~12 KB WASM binary with efficient dirty-row rendering and WebSocket connectivity to backend PTY systems.
