A v0 alternative for when you need the whole app, on every platform
v0, from Vercel, is a strong tool for turning a prompt, a screenshot or a Figma file into a polished React and Next.js interface and deploy it to Vercel in one click. People look elsewhere when they need native Swift on iOS, signed Android builds or a voice agent, want more than one model checking the plan, or want to host somewhere other than Vercel. Here's an honest look at when Quantlys is the better fit and when v0 is.
Why people look for a v0 alternative
- They need a native mobile app. v0 is built around the modern web stack, Next.js, Tailwind and shadcn/ui, and deploys to Vercel (v0 docs).
- Usage is metered in tokens. v0 bills model usage per million input and output tokens against monthly credits, and its own FAQ explains why messages can use many input tokens even when prompts are short (v0 pricing).
- The free plan has a 7 message a day limit (v0 pricing).
- They want a defended plan and tests before code ships, not a single model generating in one pass.
Where Quantlys fits
- Many models, one defended plan. The Conclave runs 5 frontier models by default, expandable to any number. Each 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.
- Local-first on your Mac. Quantlys is currently a native macOS app (Apple Silicon Mac). Your code and keys stay on your machine.
- Hosted by Quantlys or by you. Quantlys can host the apps it builds (it runs its own products this way, such as Quantlys Meeting) or deploy to a host you control.
- Bring your repo. Import an existing code repository, including one v0 has synced to GitHub, and keep building.
- Your accounts, your keys. Built in your local Xcode, signed by your Apple team and your own Android keystore. 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.
Requirements: shipping to iOS needs macOS, Xcode and a paid Apple Developer account. Android needs your own keystore and a Play Developer account.

FAQ
Is Quantlys a drop-in replacement for v0?
Not exactly. v0, from Vercel, is a browser-based builder focused on React and Next.js web apps that deploy to Vercel. Quantlys plans with a council of frontier models and ships web, native iOS, Android apps and voice agents under your own accounts, hosted by Quantlys or on a host you control.
Can I bring my v0 project to Quantlys?
Yes. v0 can sync your project with GitHub, and Quantlys can import an existing code repository and keep building from there.
Is there a free plan?
Yes. Quantlys has a free plan with no card required, running the full Conclave on free specialist models. Paid plans are Pro at $29 a month (2,000 credits) and Max at $79 a month (5,500 credits), and annual billing saves up to 16%.
Do I need a Mac?
Yes. Quantlys is currently a native macOS app, so you need a Mac to use it. From that one Mac app you can build and ship web apps, native iOS apps and signed Android apps. v0 runs in a browser.
