JAX London 2026: Dates, Tracks, Ticket Prices and the Sept 10 Cutoff

TL;DR: JAX London 2026 runs October 5 to 9, 2026 at the Park Plaza Victoria London, with the main conference and expo on October 7-8 and bootcamps and workshops on the days either side. Six tracks, all of them rebuilt around enterprise AI, and a programme the organiser describes as almost complete. The early-bird window closes on September 10, 2026 and saves up to 395 GBP, putting the 4-Day Pass at 1,259 GBP against a 1,654 GBP regular price. This is the fifteen-year-old Java conference relaunched as “The Conference for AI and Enterprise Engineering”, and that repositioning is the thing to understand before you book.

I run ZPlatform’s AI events hub, and the conference I found hardest to categorise this year is this one. JAX London has spent fifteen years as a Java and enterprise engineering event. Its 2026 homepage now leads with the line “The Conference for AI and Enterprise Engineering” and six tracks that all name AI somewhere in their scope. That is either the most honest read of where enterprise engineering went in 2026, or a rebrand chasing a keyword. Having read the whole programme, I think it is mostly the first.

Before anything else: the early-bird price ends September 10, 2026. If you are reading this the day it publishes, that is tomorrow, and it is worth up to 395 GBP. Everything else in this guide can wait until after you have decided about that.

All dates, prices and sessions below come from the official JAX London site, its programme and its ticket page, checked on September 9, 2026.

Why JAX London Stopped Leading With Java

The name still says JAX. The positioning does not.

Look at the six tracks and you can see the decision that was made:

1. Enterprise AI: Security, Scale & Performance
2. AI in Development & Agentic Systems
3. Engineering Teams in the Age of AI
4. Software Architecture for Intelligent Systems
5. DevOps, CI/CD & Platform Engineering
6. Software Engineering Practices

Four of the six put AI in the track name. The two that do not, platform engineering and engineering practices, are the plumbing the other four depend on. There is no track called Java, no track called JVM, and no track called Spring.

The organiser is explicit about the reasoning on the homepage, and the framing is unusually sober for conference marketing. Their case has three parts: companies have moved AI into production rather than experiments, AI makes system behaviour non-deterministic in a way that breaks traditional testing and debugging assumptions, and that exposes weaknesses in architecture and system design that were survivable before. That is an engineering argument, not a hype argument.

Java has not left, it has stopped being the headline. Emily Jiang of IBM is presenting “Building Intelligent Enterprises: AI-Powered Java with LangChain4j & CDI”. Ram Lakshmanan of yCrash is running “How to Build A Troubleshooting AI Agent in Java”. The JVM is still the substrate under most of the systems in the room. It is just no longer the topic.

Whether that is good news depends on what you wanted from JAX London. If you came for JVM internals, garbage collection tuning and language-level Java content, the 2026 edition is a smaller event than it used to be for you. If your actual job is bolting LLMs and agents onto a large Java estate without destabilising it, this is now one of the better-targeted conferences in Europe.

The Price Table, and Why September 10 Is the Only Date That Matters Right Now

Here is the full early-bird table. Every price is in GBP, already includes the 10 percent group discount for bookings of three or more, and excludes VAT.

Ticket	Early bird	Regular	What it covers
All Access (Conference + Bootcamp)	1,709 GBP	2,099 GBP	All conference days plus one bootcamp, devmio Fullstack, 6 months of recordings
All Access + Workshop Day	1,889 GBP	2,299 GBP	The above plus a workshop day, so the full Monday-to-Friday week
4-Day Pass	1,259 GBP	1,654 GBP	Four days of conference and workshops, devmio, recordings. Bootcamp not included
3-Day Pass	1,169 GBP	1,399 GBP	Any 3 of the 4 available conference or workshop days
2-Day Pass	989 GBP	1,199 GBP	Any 2 of the 4 available conference or workshop days
2-Day Bootcamp Pass	1,079 GBP	1,199 GBP	One two-day bootcamp, chosen at checkout
Workshop Day	719 GBP	877 GBP	One workshop day, Tuesday or Friday

The organiser marks the 4-Day Pass as its best offer, and for once the badge is on the right tier. At 1,259 GBP it is 395 GBP below its regular price, the largest absolute discount on the table, and only 90 GBP more than the 3-Day Pass. Buying three days to save 90 GBP when the fourth day costs 90 GBP is not a saving, it is a smaller conference.

Two other things the table tells you.

The bootcamp is priced as a separate product, not an upgrade. A 2-Day Bootcamp Pass at 1,079 GBP costs nearly as much as a 4-Day Pass and gets you two days with one instructor instead of four days of everything. That is a deliberate signal that the bootcamps are the premium content, and it is a fair price if you want a specific one. It is a bad buy if you were treating it as a cheap way into the week.

All Access plus a Workshop Day is 180 GBP more than All Access. That is the same 180 GBP separating the 2-Day and 3-Day passes, so the marginal day is priced consistently across the range. There is no hidden bargain tier here, which is refreshing.

After September 10, 2026 all of these move to the regular column. No second discount tier is published, so treat it as a hard cliff rather than a step down.

What Are the JAX London 2026 Dates and Where Is It Held?

JAX London 2026 runs October 5 to 9, 2026 at the Park Plaza Victoria London, on Wilton Road in Victoria. The event is hybrid, with a separate remote ticket covering live streams, virtual Q&A and online-only content.

The five days are not interchangeable, and the pass tiers only make sense once you can see the shape:

Day	Date	What runs	Hours
Monday	October 5, 2026	Bootcamp day 1	9:00 to 17:00
Tuesday	October 6, 2026	Bootcamp day 2 and Power Workshops	9:00 to 17:00
Wednesday	October 7, 2026	Main conference and expo	9:00 to 19:00
Thursday	October 8, 2026	Main conference and expo	9:00 to 19:00
Friday	October 9, 2026	Power Workshops	9:00 to 17:00

Note the ten-hour conference days. Nine in the morning to seven in the evening is a long day, and it is two of them back to back. Plan travel so you are not catching a train at 19:30 on Thursday with a laptop bag and no dinner.

The venue is a genuine advantage. Park Plaza Victoria sits roughly a hundred metres from London Victoria station, which means the Gatwick Express drops you at the door, the Victoria line connects you to St Pancras and the Eurostar in one hop, and Heathrow is a Piccadilly-then-District run away. For a conference drawing attendees from across Europe, that matters more than room quality. The organiser also lists a discount code, SOFT26, for attendees booking rooms at the hotel.

Which Sessions Are Actually Confirmed?

The programme page describes the 2026 schedule as almost complete, with final speakers still being confirmed. That is a more honest status line than most conferences publish four weeks out, and the sessions already up are specific enough to judge.

The ones I would build a Wednesday and Thursday around:

• “Tour of Agent Protocols: MCP, A2A, AG-UI, A2UI”, Mete Atamel, Google. The protocol layer is where agent integration decisions get locked in for years, and a comparative tour from someone at Google is the most reusable session on the list.
• “Four Green Ticks, Yet Still Hacked: Threat Modelling for AI Agents”, Christian Schneider. Agent security is where the gap between what teams have shipped and what they have threat-modelled is widest.
• “Low Latency Machine: Can Generative AI Write High-Performance Code?”, Mark Price, 4OTC. A testable question with a measurable answer, from the low-latency trading world where the answer actually gets checked.
• “Building Intelligent Enterprises: AI-Powered Java with LangChain4j & CDI”, Emily Jiang, IBM. The most directly practical session for anyone with a large Jakarta EE or MicroProfile estate.
• “The End of 2AM Rollbacks: 1-Click Recovery in the AI Era”, Alex Casalboni, Unleash.
• “Going From Vibe Coding to Agentic Engineering, a Step-by-Step Guide”, Matteo Emili, Avanade.
• “How to Build A Troubleshooting AI Agent in Java”, Ram Lakshmanan, yCrash.
• “Building Agentic AI with Small Language Models, Locally and Efficiently”, John Davies, Incept5.

What strikes me reading that list is how little of it is model-layer content. There is nothing about training, almost nothing about model selection, and no vendor keynote about the future of intelligence. It is protocols, threat models, latency, rollbacks and diagnostics. That is the correct set of problems for an enterprise engineering audience in late 2026, and a harder programme to assemble than a lineup of AI futurists.

If you want to arrive with context on the protocol layer those sessions keep landing on, our MCP servers report tracks that ecosystem and its security signals.

Should You Book a Bootcamp, and Which One?

Two two-day bootcamps run on Monday and Tuesday, aimed at genuinely different people.

“Building AI-Ready Systems with Clean Code, Software Design & Architecture” with Venkat Subramaniam is the architecture-side option. Subramaniam is one of the most experienced instructors on this circuit, and the framing is preparation rather than implementation: making a codebase and an architecture that can survive having AI added to it.

“Hands-On Bootcamp: Vibe Coding & GenAI Development” with John Davies of Incept5 is the build-side option, and it runs on the JAX, iJS and MLcon circuits, so it is a road-tested curriculum rather than a one-off.

The two Friday workshops, a Platform Engineering Workshop and an Agentic Engineering Workshop, are the cheaper way to get depth at 719 GBP for the day. The Tuesday pair, Ram Lakshmanan on AI-powered diagnostics and Apurva Misra on tooling and patterns for reliable AI applications, sit alongside bootcamp day two, so you cannot do both.

That is the scheduling trap worth flagging. Bootcamp day two and the Tuesday workshops are the same day. If you book the 2-Day Bootcamp Pass, Tuesday is spoken for. Read the day grid before you book the flights.

Who Should Go, and Who Should Skip It

Go if you are an architect, a platform lead or a senior engineer with an existing enterprise system that now has AI in it or is about to. The programme is aimed squarely at the integration problem rather than the greenfield one, and that is the rarer and more useful thing.

Three honest caveats.

The rebrand cuts both ways. If you have attended JAX London for years for the Java content, the 2026 edition has less of it than you expect. Look at the six track names and decide whether four AI-titled tracks is what you are buying. Nobody is hiding this, but it is easy to book on brand memory.

The final speaker list is not locked. The organiser says the programme is almost complete and final speakers are still being confirmed. The named sessions above are up now and are specific, so this is a much smaller risk than buying blind, but the timetable can still move.

Two conference days is the whole conference. Wednesday and Thursday are the event. Everything else is bootcamps and workshops with a single instructor. If your budget only covers the 2-Day Pass you are getting the conference, which is fine, but you are not getting the part the pricing is built around.

If October is impossible, the same organiser runs MLcon Berlin 2026 in November and DevOpsCon Munich 2026 from late November, both on a similar hotel-conference format with overlapping instructors. They are not substitutes for the enterprise-architecture angle, but they cover much of the same operational ground later in the year.

My go-or-skip framing: book the 4-Day Pass before September 10 if you are going at all, because 90 GBP over the 3-Day Pass buys a whole extra day and the discount on it is the biggest on the table. Take a bootcamp instead if you have one specific skill to build and no interest in the expo. Go remote if travel is the constraint, since recordings and hybrid access come with the ticket anyway. Skip it if what you wanted was a Java language conference, because in 2026 this is an enterprise AI engineering conference that happens to run on the JVM.

Common Questions About JAX London 2026

When and where is JAX London 2026?

October 5 to 9, 2026 at the Park Plaza Victoria London on Wilton Road, about a hundred metres from London Victoria station. The main conference and expo are on October 7 and 8, running 9:00 to 19:00, with bootcamps on October 5 and 6 and workshops on October 6 and 9.

When does JAX London early-bird pricing end?

September 10, 2026. The organiser advertises savings of up to 395 GBP before that date, and no later discount tier is published.

How much does a JAX London 2026 ticket cost?

Early-bird prices run from 719 GBP for a single workshop day to 1,889 GBP for All Access plus a workshop day, against regular prices of 877 GBP and 2,299 GBP. The 4-Day Pass is 1,259 GBP early bird against 1,654 GBP regular. All prices include the 10 percent group discount for three or more tickets and exclude VAT.

Is JAX London still a Java conference?

Not primarily. The 2026 edition is positioned as “The Conference for AI and Enterprise Engineering”, and four of its six tracks name AI. Java content remains, including sessions on LangChain4j with CDI and building a troubleshooting agent in Java, but the JVM is now the context rather than the subject.

What tracks does JAX London 2026 cover?

Six: Enterprise AI Security Scale & Performance, AI in Development & Agentic Systems, Engineering Teams in the Age of AI, Software Architecture for Intelligent Systems, DevOps CI/CD & Platform Engineering, and Software Engineering Practices.

Can I attend JAX London 2026 online?

Yes. A separate remote ticket covers live streaming of all sessions, virtual Q&A and online-only content, and every on-site tier includes six months of access to session recordings plus one year of devmio Fullstack access.

Is there a hotel discount for JAX London attendees?

Yes. The organiser lists code SOFT26 for attendees booking rooms at the Park Plaza Victoria London.

What I Would Do

JAX London 2026 is a fifteen-year-old enterprise engineering conference that has read its own audience correctly and rebuilt its programme around the integration problem rather than the model problem. Six tracks, two ten-hour conference days at a venue a hundred metres from Victoria station, and a session list about protocols, threat models and latency rather than futurism.

The detail worth carrying out of this guide is the shape of the price table. The 4-Day Pass carries the biggest discount on the list and sits 90 GBP above the 3-Day Pass, which is roughly what one day is worth everywhere else on that table. The organiser has priced the tier it wants you in, and in this case that tier is also the right answer.

Your concrete next step for JAX London 2026: open the official JAX London ticket page and book the 4-Day Pass before September 10, 2026, using code SOFT26 if you also need a room at the venue. While you plan, browse the AI tools I have actually tested so the architecture and agent sessions land with more context, and subscribe for AI event and deal alerts to hear when the final speaker list is confirmed.
