Gravitee

French open-core platform with first-class async API support.

By Gravitee.io, Inc. · Founded 2015 · Lille, France · private

Gravitee is the French open-core API platform with a distinctive bet, first-class support for asynchronous APIs (Kafka, MQTT, WebSocket, SSE) alongside traditional REST and GraphQL. Founded 2015 in Lille, Gravitee has carved out a niche in event-driven architectures where Kong and traditional gateways feel synchronous-only. Best fit for engineering teams running event-streaming architectures who need API governance over Kafka topics and WebSocket endpoints, not just REST. Trade-offs: smaller community and ecosystem than Kong or Tyk, brand awareness lower in North America, and the async-first positioning narrows the ideal customer profile.

Best for

Engineering teams (50-2,000 developers) running event-streaming architectures (Kafka, MQTT, WebSocket) who need API governance over async endpoints, particularly EU-based teams with GDPR data-residency requirements.

Worst for

Pure REST API needs (Kong, Tyk, cloud gateways are simpler), monetization-heavy partner programs (Apigee, MuleSoft), or US-only deployments where vendor proximity matters.

    Async API gateway generally available; differentiator vs Kong
Vendor Trust is scored independently of product quality. A great product from an unfair vendor still earns a low trust score.
