- Pay only for minutes used, not idle Mac time
- Complete end-to-end app building and publishing from iOS Simulator to App Store
- Built-in isolation and security with ephemeral sessions
| - Bounded prompt under a fixed cap while history grows, so costs per call stop climbing on long sessions
- Every run recorded with cryptographic proof: rebuilable prompts, hash-chained journal, re-runnable engine
- Resumes from crash without repeating finished actions using stable idempotency keys
- Budget enforcement before each model call, not reactive overage billing
- No model key storage or logging; your provider bills you directly
