A Bolt.new alternative for when you need native apps, not just a browser prototype
Bolt.new, from StackBlitz, is one of the fastest ways to turn a prompt into a working full-stack web app without leaving the browser. 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 token-based billing replaced by a simpler plan. Here's an honest look at when Quantlys is the better fit and when Bolt is.
Why people look for a Bolt alternative
- Token usage grows with the project. Bolt's own FAQ says most tokens go to syncing the project's file system to the AI, so the larger the project, the more tokens each message uses (Bolt pricing FAQ).
- They need a truly native mobile app. Bolt builds mobile apps with Expo (React Native), and publishing means downloading the code and running the EAS CLI on your own computer (Bolt docs).
- 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 or web. Use the native macOS app (Apple Silicon, macOS 12+) or the Quantlys web app in any browser.
- 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 Bolt 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 Bolt.new?
Not exactly. Bolt.new is a browser-based builder for quick full-stack web prototypes. 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 Bolt project to Quantlys?
Yes. Bolt can sync your project to a GitHub repository, and Quantlys can import an existing code repository and keep building from there.
Is there a free plan?
Yes. Quantlys has a free, rate-limited plan with no card required. Paid plans are $24 and $59 a month, and annual billing saves 20%.
Do I need a Mac?
For the native macOS app and for iOS shipping, yes. There is also a Quantlys web app that runs in any browser. Bolt needs only a browser.
