Partial The test runner, UI, and CLI are vibe-codeable, but the core differentiator is high-fidelity emulation of many third-party provider APIs plus a record-and-replay fault engine, which is substantial infrastructure work.
What it would actually take: Architecture would combine a Playwright-style driver, an egress HTTP/TLS proxy that impersonates provider hostnames (requiring a local CA), per-provider API emulators that match real behavior and webhooks, and a deterministic replay engine that snapshots state and injects faults. The difficult parts are faithful emulation across dozens of APIs and deterministic replay of nondeterministic app behavior, which need solid distributed-systems and networking experience.
