anywhere

Not a viewer or companion app — the whole of E, responsive. No other IDE does this.

Responsive by default the same UI scales from a multi-pane desktop split to a one-column phone view.
Reach your machine open E from your phone over Tailscale or an SSH tunnel, authenticated.
Inline media images, SVG, sparklines, and color/number widgets render right in the buffer.

The whole of this site runs as a live E window too — open the demo ↗ and shrink your window to watch it fold.

install

Installs to ~/.e/bin/e, wires $PATH and a launcher. Then run e.
