# FAQs

> Find quick answers to the most common questions about building, publishing, and managing your app with Rey — from pricing to integrations and beyond.

Rey is built to be approachable for first-time app builders and powerful enough for seasoned product teams. If you're just getting started or evaluating whether Rey is the right tool for you, the answers below cover the questions we hear most often. Can't find what you're looking for? Reach out at [hello@reyapp.io](mailto:hello@reyapp.io).

<AccordionGroup>
  <Accordion title="Do I need to know how to code to use Rey?">
    No — Rey is a fully visual app builder, so you can design, connect data, and publish a real app without writing a single line of code. The drag-and-drop editor and Rey AI handle the complexity for you. If you do know how to code, Rey doesn't get in the way; you can layer in custom logic where you need it.
  </Accordion>

  <Accordion title="Which platforms can I publish to?">
    Rey lets you publish to the **Apple App Store**, **Google Play Store**, and the **web** directly from the editor. All three targets are supported on every paid plan, including Starter. You build once inside Rey's editor and Rey handles the platform-specific packaging for each target.
  </Accordion>

  <Accordion title="What is a monthly active user (MAU)?">
    A monthly active user (MAU) is any unique user who opens or interacts with your app at least once within a calendar month. Rey counts each user only once per month, regardless of how many times they return. Your MAU total resets at the beginning of each calendar month, and [Rey app](/publishing/preview#device-preview) usage during development does not count toward your limit.
  </Accordion>

  <Accordion title="Can I try Rey before paying?">
    Yes. Every new account includes a **14-day free trial** — no credit card required. To start, visit [reyapp.io](https://reyapp.io) and click **"Join early access"** or **"Try free for 14 days"**. Your trial gives you full access to the Starter plan features, including App Store and Play Store publishing and all integrations, so you can evaluate Rey end-to-end before committing.
  </Accordion>

  <Accordion title="What happens if I exceed my MAU limit?">
    Rey will notify you as you approach your plan's MAU limit so you're never caught off guard. If you consistently exceed your current limit, you'll be prompted to upgrade to the next plan tier. Reach out to [hello@reyapp.io](mailto:hello@reyapp.io) if you need a custom limit — the Scale plan is designed exactly for this scenario.
  </Accordion>

  <Accordion title="Does Rey support custom domains for web publishing?">
    Yes. Rey deploys every web app to a `reyapp.io` subdomain by default, and higher-tier plans let you connect your own domain (for example, `app.yourcompany.com`) by adding a CNAME record in your DNS provider. See [Publish to Web](/publishing/web) for the full setup.
  </Accordion>

  <Accordion title="How does Rey AI work?">
    Rey AI is a built-in agent inside the Rey editor and understands the context of your app — its screens, data, and components. Describe what you want to build or change in plain language and the agent will generate layouts, suggest logic, or wire up logic for you. Think of it as a knowledgeable collaborator that speeds up the parts of building that would otherwise slow you down.
  </Accordion>

  <Accordion title="Can I export my app's code?">
    Rey focuses on keeping your app running and maintained inside its platform so you always have the latest optimizations and publishing pipeline. If code export is a requirement for your team, get in touch at [hello@reyapp.io](mailto:hello@reyapp.io) to discuss what's possible under a Scale plan arrangement.
  </Accordion>

  <Accordion title="How do I get support?">
    You can reach the Rey team at any time by emailing [hello@reyapp.io](mailto:hello@reyapp.io). Scale plan customers receive **priority support** with faster response times. For general questions, the Rey documentation (you're reading it now) covers setup, features, billing, and integrations in detail. The team is small and responsive — don't hesitate to reach out.
  </Accordion>

  <Accordion title="What integrations does Rey support?">
    All Rey plans include access to every integration in the platform — no add-ons or gating by tier. Current integrations include **RevenueCat** (in-app subscriptions and purchases), **AppsFlyer** (mobile attribution and analytics), **PostHog** (product analytics and session replay), and **OneSignal** (push notifications and in-app messages). New integrations are added regularly, and you can request one by emailing [hello@reyapp.io](mailto:hello@reyapp.io).
  </Accordion>

  <Accordion title="Can I use Rey to build a web app only (without a mobile app)?">
    Yes. You can publish any Rey project as a mobile-first **web app** without ever submitting to the App Store or Google Play. Web publishing doesn't require an Apple or Google developer account, and updates go live instantly. See [Publish to Web](/publishing/web) for details.
