PS Summit 2026 in Lyon: programme, dates, registration and AI sessions

In September 2026, an artificial intelligence agent paid for an online order on its own, using a French consumer’s bank card. On 5 November in Lyon, this kind of purchase will be one of the topics at PS Summit 2026, the first joint event from PrestaShop and Sylius.

The event is free, runs over two days and needs two separate registrations. Most of the programme is in English, so you can follow it comfortably even if you do not speak French.

What is PS Summit 2026?

PS Summit 2026 is the open source e-commerce event organised by PrestaShop and Sylius. It takes place on 4 and 5 November 2026 at the Centre de Congrès de Lyon and brings together more than 500 merchants, agencies, developers and software vendors. The first day is for developers, the second for the whole ecosystem, with talks and an exhibition. Entry is free with registration.

The 2026 edition marks a change of format. Since PrestaShop and Sylius came under the same leadership, the two communities have held a single event. It replaces PrestaShop Day, which until now took place in Paris.

Dates, venue and registration

PS Summit is held at the Centre de Congrès de Lyon, 50 quai Charles de Gaulle. Each day has its own registration. Seats for the 4 November workshops are free but limited. The Conference & Expo day on 5 November is open to everyone, also free of charge.

On the evening of 4 November, a Community Party brings attendees together at the Barrio Club, close to the venue. It is open to everyone registered for PS Summit. Registration is on ps-summit.com.

4 November: workshops and hackathon for developers

The first day is designed for experienced PrestaShop and Sylius developers. In the morning, two tracks let each community discover the other framework. Gracjan Józefczyk, creator of the Sylius Academy, introduces PrestaShop developers to Sylius. Krystian Podemski, PrestaShop Tech Evangelist and Core Maintainer, does the reverse for Sylius developers.

In the afternoon, both communities come together for a joint hackathon with a practical goal: building a feature as a team.

5 November: the conference programme

The day runs across two rooms, the Auditorium and Foyer 1. Announced topics include PrestaShop 10, Sylius 3, AI and e-commerce trends. Most sessions are in English, and timings remain indicative until the event.

At 9.30 am, Mikołaj Król, CEO of PrestaShop and Sylius, opens the day with a keynote. He will share his vision for both platforms and a first look at PrestaShop 10 and Sylius 3. Straight after, Olivier Binet, Managing Director of PrestaShop, gives a demo on making PrestaShop upgrades simpler.

The late morning mixes product and business: lessons learned moving from Sylius 2 to Sylius 3, a talk by Ben Marks (The PHP Foundation) on where open source stands as AI spreads, and a round table on B2B with PrestaShop and Sylius.

The afternoon gives AI a prominent place. At 4.05 pm, a merchant round table led by Angelo Aouad, Country Manager France at PrestaShop, is held in French. The day ends with the Community Awards and closing words from Mikołaj Król.

AI and agentic commerce in the afternoon sessions

Three afternoon sessions deal directly with AI applied to commerce. At 2 pm, PayPal gives a talk on agentic commerce in the Auditorium. At the same time, in Foyer 1, PrestaShop’s security team and the CTO of 202 ecommerce explain how AI is changing security on the platform. At 2.35 pm, Ma Coque and the PrestaShop product team give a live demo of the Ask IA assistant on a real shop.

Agentic commerce refers to purchases made by an AI agent on behalf of a customer, within limits set in advance: budget, product categories, approved merchants. The topic became concrete in September 2026. Visa, Revolut and Cleverbridge completed a payment in France started by My Agent, Visa’s test agent, on a real Revolut card. A Visa Payment Passkey, registered beforehand with the cardholder’s fingerprint, replaced the text message code. The Strong Customer Authentication required by PSD2 did take place, and the bank kept control of the authorisation.

For a PrestaShop shop, the consequences sit before the payment. The agent has to load your pages, read your product pages and complete the order without being blocked by the firewall. At 77-24, the dedicated WAF and the patcher belong to a proprietary security stack whose rules are adjusted shop by shop. Shopping agents add a category of traffic to handle separately, distinct from malicious bots.

Which sessions to follow for your role

If you run a shop, the keynote, the upgrades demo and the talks from Sendcloud on delivery and GetResponse on customer retention give a clear picture of what is coming. The merchant round table is in French, so it suits French-speaking visitors best.

For an agency, the B2B round table and the Soledis session on the standout features of PrestaShop and Sylius help prepare client projects for 2027. For developers, 4 November is the day not to miss. On 5 November, the security session and the Sylius talk on using AI in a Sylius project follow on from the workshops.
