Wterm Web Terminal

aradotso/trending-skills

A web terminal emulator with a 12 KB Zig/WASM core that renders to the DOM instead of canvas, so you get native text selection and browser search for free. Ships with React hooks and vanilla JS bindings, plus a JustBash transport that runs a shell entirely in the browser without a backend. The real win here is the DOM rendering approach. Most terminal emulators paint to canvas for performance, but wterm trades a bit of speed for actual accessibility and zero-friction copy/paste. Comes with WebSocket PTY support, VT100/xterm parsing, and theming via CSS custom properties. If you're building a coding playground, admin dashboard, or anything that needs a terminal without fighting the browser, this is lighter and more integrated than xterm.js.

wterm Web Terminal Emulator

Skill by ara.so — Daily 2026 Skills collection.

wterm ("dub-term") is a web terminal emulator with a Zig/WASM core (~12 KB binary) for near-native VT100/VT220/xterm parsing. It renders to the DOM — giving you native text selection, copy/paste, browser find, and accessibility for free. Supports WebSocket PTY backends, alternate screen buffers, 24-bit color, scrollback, and themes.
