The fairest way to compare Cursor and Dyad is to judge them on one concrete job: taking a real software spec, scaffolding a working application, and then iterating safely across a multi-file codebase. They diverge here because Cursor is an AI-first editor built on a VS Code fork with cloud-backed assistance, while Dyad is a local-first builder centered on running code and models under your control.
This job exposes the failure modes that actually matter once the demo ends. If the tool loses track of repository context, burns through usage during repair loops, or leaves you with awkward code ownership tradeoffs, the speed gain disappears and the maintenance bill arrives immediately.
