Gravitee

Gravitee (gravitee.io) is an open-source, event-native API management platform recognised as a Leader in the Gartner® Magic Quadrant™ for API Management for two consecutive years. It provides a unified platform for designing, deploying, securing, monitoring, and productizing APIs across synchronous and asynchronous protocols — including REST, SOAP, WebSockets, Webhooks, GraphQL, Kafka, and MQTT — without requiring separate tools for each protocol. In 2026, Gravitee has positioned itself at the forefront of AI Agent Management, offering centralised identity, access control, MCP tool governance, and agent-to-agent (A2A) traffic management for enterprise AI deployments.

The platform's core philosophy is to act as a universal governance and publication layer across an organisation's entire API estate — including third-party gateways like AWS API Gateway and Google Apigee. Rather than replacing existing infrastructure, Gravitee federates multiple gateways under a single management plane, providing a unified view for discovery, subscription, policy enforcement, and analytics. This approach reduced one enterprise's average developer onboarding time from 30 days to one day in a documented case study. Gravitee is available as open source for self-hosting, as a Gravitee-hosted cloud (SaaS), or in a hybrid deployment combining both.

How Gravitee Works

Organisations connect their API backends and existing gateways to Gravitee's management API. They then define APIs through the visual console, applying policies — authentication, rate limiting, IP filtering, transformation, caching, logging — from a drag-and-drop policy studio. The developer portal provides a self-service catalogue where consumers discover, subscribe to, and obtain credentials for APIs without manual intervention from the API team. Event-driven APIs are published the same way as REST APIs, exposing Kafka streams natively to external consumers through standard API subscriptions. For AI workloads, Gravitee's agent management layer governs AI agent identity, tool access via MCP, and agent-to-agent traffic with the same policy infrastructure used for traditional APIs.

Key Features

• AI Agent Management — centralised governance for AI agent identity, MCP tool access, and agent-to-agent (A2A) API traffic within the same platform as traditional API management
• Event-native API Gateway — natively exposes Kafka streams and event brokers (MQTT, WebSockets, Webhooks) to API consumers without custom integration work
• Multi-gateway federation — manages APIs across AWS API Gateway, Google Apigee, Azure API Management, and other third-party gateways from a single control plane
• Policy Studio — drag-and-drop visual editor for composing authentication, rate limiting, transformation, caching, and security policies on any API
• Developer portal — self-service API catalogue for discovery, subscription, credential management, and documentation, reducing consumer onboarding time
• Access Management (AM) — integrated FAPI-compliant identity and access management with OAuth 2.0, OpenID Connect, and SAML support
• API Analytics and Monitoring — real-time usage metrics, latency dashboards, error tracking, and configurable alerting across all APIs
• FAPI compliance — Financial-grade API (FAPI) compliance for regulated industries including financial services and healthcare
• Open source core — full API management capabilities available as open source under the Apache 2.0 licence; deploy on-premises or self-managed cloud
• Kubernetes operator — Gravitee Kubernetes Operator for declarative, GitOps-native API management in containerised environments

• Enterprise — from $2,500/month — Gravitee-hosted or hybrid cloud deployment with advanced enterprise features: dedicated support, SLA guarantees, advanced analytics, multi-environment management, enterprise plugins, audit logs, and FAPI compliance tooling. Pricing varies by API call volume, environments, and contract terms.

Open-source self-hosting is available at no cost. Enterprise pricing is negotiated based on usage and requirements. Always verify current rates at gravitee.io/pricing.

Who Should Use Gravitee?

Gravitee is designed for enterprises and large organisations that manage complex, multi-protocol API portfolios at scale — financial services, telcos, healthcare, and large technology companies that need FAPI compliance, event-driven API support, and centralised governance across multiple cloud and on-premises environments. Its multi-gateway federation capability is uniquely valuable for organisations that already run multiple API gateways and need a unified management layer. Teams with simpler requirements — a single REST API backend with standard rate limiting and documentation — will find Gravitee's capabilities exceed their needs and its enterprise pricing hard to justify. Smaller teams may better serve their requirements with Postman or Stoplight for design and documentation alone.
