Quick picks
- Polished hosted web app, fast: Lovable.
- Full cloud IDE with hosting: Replit.
- Web, iOS, Android or voice agent, multi-model plan, your own signing: Quantlys.
Where Quantlys fits
- Many models, one defended plan. Each model drafts on its own, the models peer-rank each other's drafts, and an Arbiter merges the best into one plan and records why.
- Web, iOS, Android and voice agents from one workflow, with real native Swift on iOS, proven through TestFlight. Android builds are signed with your own keystore, available to every user today.
- Your accounts, your keys. Built in your local Xcode, signed by your Apple team and your own Android keystore.
- Store blockers caught early. Ten App Store and six Google Play blockers are checked on your machine before upload.
- Tests, not vibes. Deterministic QA runs offline with model calls stubbed, and every handoff and decision is logged.
- Compose your own crew. Start with PM, architect, developer and QA agents, or define your own roles, tools and standards.
Requirements: shipping to iOS needs macOS, Xcode and a paid Apple Developer account. Android needs your own keystore and a Play Developer account.
