OpenAPI Conference

11 December 2025

CNIT FOREST 2 Place de la Défense, 92092 Puteaux

The OpenAPI Conference brings together practitioners, architects, and strategists who shape how APIs are designed, governed, and scaled. It’s a meeting point for those turning API standards into practical value, across industries, teams, and tools. Participants explore how specifications like OpenAPI, Arazzo, and Overlay underpin reliable interfaces, enable automation, and make APIs discoverable and secure.

From hands-on sessions about API design and lifecycle management to high-level discussions on interoperability and organizational strategy, the OpenAPI Conference highlights the patterns, practices, and emerging trends that define the state of modern API ecosystems. It’s where the API community learns from each other, aligns on standards, and moves the web forward — one contract at a time.
