The content

One job: building software that holds up

Devs talking to devs. Software architecture, cloud, DevOps, security, AI engineering, performance, quality — first-hand experience, deep dives into brand-new tech, craft. A generalist, cross-cutting format that goes beyond any single ecosystem, with the same level of technical rigour from the first talk to the last.

Before you book

One ticket, seven tracks, from code to AI.

Your Developers ticket gives access to the five technical tracks and the two AI Builders tracks. No need to choose between code and AI. Architect, DevOps, security expert, QA or a dev who codes with AI: this ticket is yours.

What about the programme?

Three names already announced: David Rousset, Melanie Guittet, Fabian Vilers. The rest of the line-up will be revealed by November. And the framework is known: ten editions, more than 40 talks, 7 rooms.

What about my day?

7 parallel rooms, 50 talks, in a single day. Every hour, you'll find at least one session that sparks your curiosity. Sometimes you'll even have to make tough choices. That's why it's worth coming as a team — to capture as much knowledge as possible.

What about the level?

Devs talking to devs, without dumbing things down. Talks assume you code, not that you already know the topic. With 7 rooms, you go deeper or lighter depending on what you came for.

This track is for you if

You build, you ship, you optimise

Developer, architect, tech lead, DevOps or platform engineer, security expert, data or AI engineer, tester. If tech is your job, you're in the right place.

Taking the stage

International experts and devs coming to talk about what they're passionate about — architecture, cloud, security, AI engineering, craft. The first names are in, more are coming by October.

Tickets

Your Developers ticket

Developer, architect, tech lead, DevOps or platform engineer, security expert, data or AI engineer, tester. A full day: you go from a deep dive into a fresh technology to a production war story, then to a craft session. Between talks, the networking that matters — the kind built between people who do the same job. No replay: the energy of a room can't be rebroadcast. It's a choice, not an oversight.

Partnerships

DevDay offers three types of tickets, designed for its three audiences: Developers, AI Builders and Executives. Each type gives access to a dedicated track, with content tailored to each profile and its level of technicality.

Tickets

No, DevDay aims to bring together everyone in tech who contributes to software development. The audience is mostly developers, but also AI Builders and business leaders. The programme is designed to offer relevant content to all three profiles, at varying levels of technicality.

Programme

No. DevDay is open to all profiles, whether it's your first talk or your tenth. What matters is the value of what you have to share. Speakers are chosen by a selection committee that assesses sessions on their relevance and fit within the programme.

Call for Papers

Absolutely! DevDay is the ideal place to meet and talk with other developers, AI Builders and leaders of the tech scene. Dedicated moments throughout the day give you time to network: breaks, lunch and the afterwork at the end of the event.

Logistics

Yes. An invoice in your company's name is issued for each ticket. For a purchase order or a specific procurement procedure, contact contact@devday.be.

Tickets

DevDay is mainly held in French, reflecting its roots in Wallonia. Some sessions may be given in English depending on the invited speakers.

Programme

DevDay is looking for concrete first-hand experience: a difficult technical decision, a system put to the test, an architecture that evolved under constraint. DevDay is committed to putting both international and local experts on stage. We also make sure the diversity of the profession is represented. Vendor proposals and purely promotional talks are not accepted.

Call for Papers

Yes, the Palais des Congrès de Mons is fully accessible to people with reduced mobility. For any specific needs, contact contact@devday.be.

Logistics

Yes, and it's even strongly encouraged: coming as a team multiplies what everyone gets out of it. A group rate is available to all teams of 5 people or more. And for companies that want to offer more to their teams, we can design a tailor-made premium experience (dedicated welcome, reserved seats, branded goodies and t-shirts…) — write to us at contact@devday.be to discuss a premium package.

Tickets

Yes, tickets are personal but transferable up to 7 days before the event by contacting contact@devday.be with the details of the replacement attendee.

Tickets

DevDay is an in-person experience: sessions are not recorded for replay. That's what makes the encounters, the conversations and the energy of the day unique.

Programme

A reduced rate is available for students, in collaboration with DevDay's partner schools and universities. If you're a student and interested, contact your institution's management to find out whether participation is planned — and feel free to put us in touch with your school (contact@devday.be) if needed.
