The short version

  • Each has a real cost: Flutter dart is used almost nowhere else, so the language itself is a hiring and learning cost; RevenueCat the fee is 1 percent of revenue measured before the app store takes 15 or 30 percent, so the effective rate against money you actually receive is closer to 1.2 to 1.4 percent, a distinction that is easy to miss when modelling the cost.
  • They diverge on capability: Flutter covers Single codebase, many targets, RevenueCat covers Cross-platform entitlements.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Flutter

  • Dart is used almost nowhere else, so the language itself is a hiring and learning cost
  • Because Flutter draws its own widgets, apps can feel subtly unlike the platform unless deliberately styled per-platform
  • Binary sizes are larger than equivalent native apps because the engine ships with the app
  • Access to a brand-new platform API waits on a plugin, or on writing platform channel code yourself

RevenueCat

  • The fee is 1 percent of revenue measured before the app store takes 15 or 30 percent, so the effective rate against money you actually receive is closer to 1.2 to 1.4 percent, a distinction that is easy to miss when modelling the cost.
  • The bill scales with success rather than with usage or headcount, so the largest invoice arrives in the month of your best growth, which is exactly when cash is committed elsewhere.
  • At high revenue the arithmetic turns against you: 1 million USD of monthly tracked revenue is 10,000 USD a month, at which point building and staffing receipt validation in-house becomes a serious comparison rather than a hypothetical one.
  • Subscriber and entitlement state lives in the vendor system, so migrating away requires re-validating historical receipts and running dual sources of truth during the transition, and that switching cost grows the longer you stay.
  • Growth features such as paywalls and web funnels are charged at the same 1 percent of what they track, so revenue attributed to those tools is billed even where you already had the infrastructure to handle it.

Answered from the vendors’ own pages

Flutter: Is Flutter free?

Yes. Flutter is open source with no licence fee. The framework is under a Creative Commons Attribution 4.0 licence and its code samples under the 3-Clause BSD licence.

RevenueCat: Is it really free to start?

Yes, up to 2,500 USD in monthly tracked revenue, with all features included and no seat charges.

Flutter: What language does Flutter use?

Dart, a language Google designed for fast startup and ahead-of-time compilation to native code.

RevenueCat: Is the 1 percent taken from gross or net revenue?

Gross. The vendor bases pricing on pre-platform-cut revenue, so the app store commission is not deducted before the fee is calculated.

Flutter: Can Flutter build for more than mobile?

Yes. The same codebase targets iOS, Android, web, Windows, macOS, Linux and embedded devices, though mobile remains the most mature target.

RevenueCat: What happens if RevenueCat is unavailable?

The SDK caches entitlement state locally so existing subscribers usually keep access, but new purchases and restores depend on the service.

Flutter: How is Flutter different from React Native?

Flutter draws its own widgets with its own engine, so the result is pixel-identical across platforms. React Native renders to the real native components of each platform. Flutter uses Dart; React Native uses JavaScript and React.

RevenueCat: At what point should I build this in-house?

Somewhere above a few hundred thousand dollars of monthly tracked revenue the annual fee funds engineers, though it also buys cross-platform correctness you then own forever.
