TL;DR — Five picks for a Europe-based senior dev / architect deciding where to go between May 2026 and Q1 2027:
→ Pure architecture, broadest program: iSAQB Software Architecture Gathering, Berlin, 16–19 Nov 2026[3].
→ Domain modelling depth: DDD Europe, Antwerp, 8–12 Jun 2026[2].
→ Architecture × engineering leadership: GOTO Copenhagen, 28 Sep–2 Oct 2026[6].
→ Best value, broad signal: Craft Conference, Budapest, 4–5 Jun 2026, €499 + VAT[7].
→ Research × industry crossover: ICSA 2026, Amsterdam, 22–26 Jun 2026[4].
QCon London[1], OOP Munich, NDC London and Voxxed Days Amsterdam already happened in early 2026 — see the bottom of this page.
The premier picks
iSAQB Software Architecture Gathering practitioner
The most architecture-pure event on this list: 7 tracks, 40+ sessions, 50+ speakers, run by iSAQB with heise medien[3]. Workshops on Day 1, conference Days 2–3, deep-dive workshops Day 4. CPSA-aligned, but English-speaking and international.
DDD Europe DDD
The world's leading DDD conference — strategic design, event-driven architecture, socio-technical systems[2]. Aimed squarely at experienced engineers and architects in complex domains. Sister event Data Mesh Live runs Jun 11–12 in the same venue.
GOTO Copenhagen practitioner
"Engineering for Reality" theme: distributed systems, observability, resilience, agentic software, green computing[6]. Strong mix of staff-level engineers, architects, and team leads.
Craft Conference practitioner
Two days, ~2,000 attendees, headline keynote by Gergely Orosz (The Pragmatic Engineer); Neal Ford and Kenny Baas-Schwegler also confirmed[7]. Best price-to-signal ratio of the practitioner-tier events.

CFP status (as of 2026-05-01)
For senior devs who want to speak rather than just attend, here's where the architecture-conference CFPs stand:
| Conference | CFP status | Action |
|---|---|---|
| iSAQB Software Architecture Gathering | ⚠ Opens 5 May 2026, closes 9 Jun 2026[24] | Bookmark the CFP page; submit week of May 5 |
| DDD Europe | ✗ Closed 16 Jan 2026[25] | Plan for 2027 cycle |
| GOTO Copenhagen | n/a — invitation/program-committee curation | Pitch via speakers page |
| Craft Conference | ✗ Closed 31 Jan 2026[26] | Plan for 2027 cycle |
| ECSA 2026 | ✓ Open: Industrial / Tools abs 1 May, Industrial papers / Workshops 8 May, Workshop papers 15 May, Open Science 19 Jun, Journal First 26 Jun[27] | The realistic 2026 publish-window for European arch work |
| ICSA 2026 | ✗ Research closed Dec 2025; Open Science Challenge closed 31 Mar | Plan for ICSA 2027 |
| Devoxx UK | ✗ Closed 9 Jan 2026 | Plan for 2027 |
| Devoxx Belgium | ⚠ Opens 1 Jun 2026, closes 17 Jul 2026[9] | Architecture track is competitive — submit early |
| JAX London | ✗ Closed 13 Apr 2026[28] | Plan for 2027 |
| NDC Oslo | ✗ Closed 19 Apr 2026; 150 speakers / 160 sessions selected | Plan for 2027 |
| CONVEX Summit (ex-GSAS, Madrid) | n/a — not publicly visible | Verify directly with organisers |
If your goal is "publish architecture work in 2026 with reasonable European reach", ECSA's industrial track at 8 May is the realistic window. Otherwise, iSAQB SAG (5 May - 9 Jun) and Devoxx Belgium (1 Jun - 17 Jul) are the two practitioner CFPs worth waiting a week for.
Pick by what you want out of it
"I want pure software architecture content, in English"
iSAQB Software Architecture Gathering (Berlin, Nov)[3] is the cleanest match. ICSA (Amsterdam, Jun)[4] if you don't mind academic flavour and like the working-conference format.
"DDD, event storming, modelling complex domains"
DDD Europe Antwerp Jun 8–12[2]. Smaller-scale community alternative: KanDDDinsky in Berlin (community-driven, dates pending)[19].
"Architecture in the broader engineering-leadership context"
GOTO Copenhagen[6] or Craft Conference[7]. Both blend technical depth with team/leadership tracks.
"German-speaking community, CPSA orbit"
iSAQB Software Architecture Forum in Munich (Jun 16–17)[21] is the new community-tier event — 23 sessions, CPSA-aligned[14]. OOP (next edition Feb 2–5, 2027 in Munich, MOC venue) remains the marquee German-speaking architecture event[13].
"Java ecosystem with arch tracks"
Devoxx Belgium (Antwerp, Oct 5–9)[9] is the flagship; JAX London (Oct 5–9, hybrid)[8] if you want London + remote option. Devoxx UK (May 6–7)[10] is a tighter 2-day version.
"Cheap, regional, still substantive"
Voxxed Days Bucharest tagged 50% architecture content at €120–180 a ticket[16] (Apr 28–29 — already past). The Voxxed Days circuit (Zürich, CERN, Ticino, Amsterdam) covers architecture every year at this price point.
QCon — what's the deal
QCon London ran 16–18 March 2026 with 75+ speakers across 15 tracks including Architecture in the Age of AI, Architecting for Resilience, and Debugging Distributed Systems[1][15]. It's the European stop of QCon and remains the practitioner-focused event of choice for senior engineers and architects — InfoQ-curated, very strong for production-system patterns. The 20th-anniversary 2026 edition leaned hard into agentic AI and platform ROI[22]. QCon London 2027 typically runs in mid-March; if architecture is your full-time job, put it on the calendar now.

Source notes & caveats
- The dev.events architecture listing tracks 86 events tagged "architecture" across Europe in 2026/2027[20] — useful as a discovery feed beyond the picks above.
- O'Reilly Software Architecture Conference no longer runs in-person — O'Reilly cancelled all in-person conferences and moved to online Superstreams. Don't wait for a Berlin/Amsterdam revival.
- GSAS has rebranded to CONVEX Summit and moved from Barcelona to Madrid, 17-18 June 2026[23] — earlier in the year and a different city than this report originally surfaced. CFP status not publicly visible; verify directly with organisers.
- KanDDDinsky 2026 is in CFP / planning at time of writing — community-organised DDD event in Berlin[19].
