wterm renders browser terminals as semantic HTML

wterm is a web terminal emulator that renders directly into the DOM, so users get native text selection, copy and paste, browser find, and screen reader support without extra work. The core is a small Zig codebase compiled to WebAssembly that parses VT100, VT220, and xterm escape sequences, and the project ships with DOM, vanilla JS, and React packages for integration.

// ANALYSIS

Hot take: this is a real UX and accessibility improvement, not just another terminal UI wrapper, because it treats terminal output as structured content instead of pixels.

–DOM rendering is the main differentiator: selection, clipboard, search, and accessibility fall out naturally.
–The Zig plus WASM core suggests the project is aiming for low overhead and near-native parsing performance.
–React support lowers adoption friction for web apps that need an embedded terminal.
–The feature set is practical, especially alternate screen buffer support, scrollback, auto-resize, and 24-bit color.
–The announcement is strongest as an open source infrastructure release rather than a flashy product launch.
