DevOps REX 2026

DevOps REX is a French-language conference built entirely on experience reports: "REX" stands for retour d'expérience, and the organisers promise no theory and no sales pitches on the main stage. Its audience is French-speaking DevOps engineers, platform and security teams, and the managers steering organisational change. The seventh edition moves to Hall 5.2 at Paris Expo Porte de Versailles on 9 and 10 December 2026, with seats limited to about 400. A programme committee picks around 20 talks across six themes: DevOps strategy and culture, DevSecOps (supply chain, SBOMs, NIS2 and CRA compliance), FinOps, platform engineering and developer experience, AI and DevOps, and digital sovereignty. Day one leans towards DevOps transformation stories and day two towards DevSecOps. New for 2026 are an unconference slot where attendees vote on discussion topics, a ten-minute open demo corner, and office hours with main-track speakers. Speakers in 2026 come from companies such as Michelin, Back Market, Bpifrance and VideoLAN. A two-day pass costs EUR 430 including VAT, or EUR 365.50 with the early-bird online offer, and also admits holders to Open Source Experience, the open-source business show running alongside. Talks from the 2024 and 2025 editions are published free on the event's replay pages and YouTube channel.
