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.
