Should I vibe-code or build my own Sketch clone from scratch?+
Our build verdict for Sketch is KINDA (the core, yes. the polish, no). The visible interface design loop is buildable, but a credible replacement needs more than the first screen. Sketch earns its keep through editor polish, assets, algorithms, so expect a weekend or multi-day build and a narrower personal scope.

It is browser-first rather than a native offline Mac editor, with a much smaller plugin ecosystem than Sketch.
