Gravitee

Gravitee builds an open-source based platform that companies use to control how APIs, event streams and AI agents are exposed and consumed. Its API management product combines gateways, a developer portal, API design, observability and governance across multiple gateways and brokers. Event management capabilities proxy and secure Kafka streams and mediate between protocols. Newer agent management capabilities add an AI gateway, a catalog of tools and MCP servers, and security controls for agent traffic, while an access management product handles authentication and fine-grained authorization for applications and agents. The software runs self-hosted, hybrid or as a managed cloud service, and a free community edition is available under the Apache 2.0 license.
