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; Gravitee the entry paid API management tier is $2,500 a month and includes a single production gateway
  • They diverge on capability: Flutter covers Single codebase, many targets, Gravitee covers API Gateway.
  • 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

Gravitee

  • The entry paid API management tier is $2,500 a month and includes a single production gateway
  • Event management is priced separately, starting at $1,250 a month for the Comet tier
  • Tiers are gated on gateway and broker counts, so scaling horizontally means moving tier rather than paying incrementally
  • Data logging masking and other enterprise features are withheld from the lowest paid tier
  • 24/7 support requires the top Universe tier

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.

Gravitee: What is Gravitee's pricing model?

Gravitee uses a tiered subscription model with monthly flat pricing. The Planet tier for API Management starts at $2,500/month with one production gateway, while the Comet tier for Event Management starts at $1,250/month.

Source
Flutter: What language does Flutter use?

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

Gravitee: Are there hidden fees with Gravitee?

No. Gravitee explicitly states there are no hidden fees, and all tiers include unlimited users and unlimited APIs under management.

Source
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.

Gravitee: What does higher tier pricing include in Gravitee?

Higher tiers add more production gateways, enterprise plugins, and enhanced support levels ranging from Gold to Platinum/Diamond support.

Source
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.
