TL;DR Cassis hosts no public IT conferences. It’s a corporate-seminar venue town — the Oustau Calendal congress centre handles team off-sites up to 300 people. Developer events are in the neighbouring cities: KCD Provence on 10 Dec 2026 in Aix-en-Provence (600+ expected, Kubernetes / cloud-native) [1] and Agile Tour Aix-Marseille every autumn (~270 attendees). [8] Both are under 45 minutes by car from Cassis.
Cassis as a conference venue, not a conference city
Cassis (~8,800 residents) is built for tourism and wine, not tech summits. The tourism office markets it for MICE — Meetings, Incentives, Conferences, Events — with 11 registered venues and a formal congress-request desk. [3] [4] None of those venues hosts a recurring public IT conference; the use case is private: a squad of engineers converging for a sprint review, architecture off-site, or leadership retreat where a cliff-top terrace doubles as a whiteboard backdrop.

Practical tips for the Cassis-based attendee
- By car: Cassis → Aix-en-Provence ~40 min (A50 → A51); Cassis → Marseille ~25 min (A50). Conference parking at both destinations is typically free or cheap.
- By train: Gare de Cassis is on the Marseille–Toulon TER line; Marseille Saint-Charles in ~25 min (hourly). Marseille → Gardanne (Agile Tour venue) by train in ~20 min.
- Pricing window: Cassis hotel rates drop sharply after October, making a KCD Provence trip (10 Dec) economical to combine with a Provence weekend.
