About Gravitee

Gravitee is an open-source API and event management platform founded in 2015 in Lille, France, with offices today in Lille, London and Denver. The platform unifies API management, event streaming and AI agent management, fronts the Gravitee Gateway alongside AWS Gateway, Apigee, Azure, IBM and Confluent, and ships dozens of pre-built policies for rate limiting, traffic shaping and usage analytics. APIs are surfaced through a single developer portal where consumers subscribe and view analytics. A free open-source edition is available; the commercial subscription starts at $2,500/month with unlimited API calls and users.
