Developer abandons contentEditable and draws an entire text editor on a 2D canvas

Tasfer: a text editor drawn on a 2D canvas

Frustrated by contentEditable's quirks, Hamza built Tasfer, a text editor that measures and paints every letter, cursor, selection, and line break onto an HTML5 canvas, with a hidden input only to catch keystrokes. It is local-first with no accounts or cloud copy, syncs via a self-implemented CRDT over encrypted WebRTC, and now runs on web, desktop, and mobile. The engine is open source under MIT, the app under AGPL.
