Build limits
Section titled “Build limits”- One build at a time per platform. You can’t queue multiple Android builds simultaneously, but you can run an Android build and an iOS build in parallel.
- Builds are queued if the system is busy. Your build enters a queue and starts automatically when capacity is available.
- Build artifacts are available for download after completion. Download links remain accessible in your build history.
Preview limitations
Section titled “Preview limitations”The Live Preview is a Flutter web build running in your browser. It’s great for rapid iteration but has some differences from native devices:
- Screenshot cropping — Chrome and Edge only. The button is hidden in Firefox and Safari.
- Device mockup — visual representation only, not device emulation. Screen dimensions match but rendering may differ slightly.
- Plugin limitations — some Flutter plugins don’t work in web preview: camera, sensors, Bluetooth, NFC, and other hardware APIs.
- Performance — animation smoothness and load times in preview may differ from a native build on a real device.
Account limits
Section titled “Account limits”- Unlimited projects on all plans, including Free.
- 20,000 token minimum to create a new project. If your balance is below this, you’ll be prompted to upgrade your plan.
- Tokens do not roll over. Each billing cycle starts with a fresh allocation. See Token System.
