🎟️ WebExpo 2026: The biggest Czech web conference turns 18

If you’re looking for a European web conference that isn’t in Berlin, Amsterdam or London, put Prague on the list. WebExpo celebrates its 18th edition on May 27–29, 2026, and it has quietly become one of the larger events of its kind in Central Europe: around 1,600 attendees, more than 70 speakers, two days of talks and a day of workshops.

I’ve watched it grow from a gathering of the Czech web community into a conference where speakers fly in from all over the world. What it kept from the early years is the scale that still allows real conversations, which is rarer than it sounds once a conference passes a thousand people.

Why it’s worth the trip

The venue is the main argument for visitors. The conference takes place in and around Lucerna, an early 20th-century palace with a passage, cinema and a large hall right off Wenceslas Square in the centre of Prague. You walk out of a talk and you’re in the middle of the city, which makes the evenings as useful as the programme.

The audience is mixed in a good way. In two days you meet frontend and backend developers, designers and researchers, marketers, founders and people from large tech companies. Evening parties and mentoring sessions are part of the programme, so the networking doesn’t depend on catching someone in a coffee queue.

Prague is also easy to reach and, compared to Western European capitals, still reasonable for accommodation and food. Many visitors add a weekend to the trip, which is easy to justify in a city like this.

Workshops have limited capacity and some of them sell out early. If one of them is the reason you’re coming, don’t leave the order to the last week.

What I’d pick from the programme

The programme covers frontend, design, AI, business, marketing and security, with more than seventy talks and workshops. Rather than list my favourites one by one, here’s what I’d suggest depending on why you’re coming.

If you build things

Start with Ladislav Prskavec, who writes an MCP server in Go live and plugs it into an AI client. It’s the most practical way to see how agents get access to observability data and internal tools. Then go to Krasimir Tsonev’s tour of JavaScript’s strangest corners, from [] == ![] evaluating to true to one line of code hijacking the clipboard. It’s entertainment, but the kind that makes you check your own code afterwards.

If you build AI products

Tejas Kumar from IBM makes the case that model choice matters less than taste. His examples are concrete product decisions: streaming instead of waiting for a full answer, interfaces that go beyond a chat box, and speed treated as a feature. If you ship anything with an LLM inside, it’s the talk most likely to change a design decision next week.

If you run a SaaS

Two talks belong together here. Vladana Bačová dissects a SaaS funnel that was leaking users and shows, with real numbers, which fixes turned dead leads into customers. Dima Melnik then argues that most founders simply charge too little, and that the way a price is packaged changes what people are willing to pay more than the product does.

If you live from search traffic

Aneta Holá and Aleš Moravec cover the shift from SEO to AIO and GEO, optimising for answers generated by AI rather than for blue links. The useful part is measurement: how to tell whether you’re visible when fewer people click through at all.

The hallway track

The best part of WebExpo is still what happens between the talks. I always run into former colleagues and people I’ve worked with at different points of my career, and many of the most useful conversations happen in the passage or at the evening parties.

For a visitor from abroad that’s the real value: two days with a large slice of the Central European web industry in one building, in a city worth visiting on its own. The full programme is on webexpo.net.
