apidays Paris December 2023

Post Event Report

Conference Theme

In today’s intricate digital landscape, APIs have emerged as powerful conduits for innovation, bridging the gaps and unlocking new realms of possibility. This year, apidays Paris revolves around four strong pillars: “Software, Sovereignty, Society, Sustainability.”
Software: Software & APIs are the pulsing heart of the digital revolution, from the frameworks that power global platforms to the microservices optimizing niche solutions, Serveless, Kubernetes, Kafka, and many other technologies.
Sovereignty: How should sovereignty be defined in the age of the cloud, decentralization, and ubiquitous connectivity, all while empowering individuals and organizations to chart their distinct digital paths?
Society: Let’s understand the societal implications of rapid technological advances to ensure that we leave no member of society behind, fostering an equitable and harmonious future.
Sustainability: Let’s explore the sustainable development, deployment, and management of software solutions to grasp the importance of eco-friendly digital infrastructures, ethical AI, and the long-term impact of our digital choices.

OAI Track Program Recap

apidays Paris was the 3rd and largest OpenAPI track program so far which consisted of 11 presentations over 3 sessions. The event was very well-attended with ~3500 registrations. Loads of posts to LinkedIn, here are the main posts from the event:

The OAI Track sessions were happening on two days, two of them on December 6 and one on December 8. There were more people on December 6 but that was probably because there were fewer competing tracks on that day. On December 8 we were in the afternoon, so some people were already leaving but there still was competition from 7 other tracks. However, in all sessions we had full rooms and good engagement from the audience, oftentimes hanging out in the room after the session to further discuss with speakers.
