Three caveats on the table
- Devoxx France already happened (22-24 Apr) [9]. For French-speaking architecture content, the next live CFP is MiXiT 2026 [23] (Lyon, 16-17 Apr 2026 — also past) and BDX I/O [24] (Bordeaux, 29-30 Oct 2026; CFP not yet posted). France’s 2026 architecture-conference calendar is thin after Devoxx; most of the wave is in 2027.
- iSAQB SAG’s CFP is only a few days from opening, not actually open at the moment you read this on 30 Apr [2]. It’s grouped as ⚠ rather than ✓ for that reason — but if architecture is your topic, this is the highest-signal CFP in DE for the year.
- Devoxx Belgium’s CFP is six weeks from opening [10]. Same caveat — flagged for planning, not for submitting today.
ICSA 2026 — what’s still useful even though the main CFP is closed
The 23rd IEEE International Conference on Software Architecture is hosted at VU Amsterdam, 22-26 Jun 2026 [3]. For practitioners, the Software Architecture in Practice track (papers due 8 Dec 2025) is closed, but the conference is the densest place this year to encounter recent peer-reviewed architecture research in Europe — workshops, tutorials, and the showcase track all keep their programs visible until the event [4]. If you want the academic side of the field, attend; if you wanted to publish, that train left in December.
ECSA 2026 — the European academic counterpart, with multiple still-open windows
ECSA 2026 (20th European Conference on SW Architecture) is in Bolzano, Italy, 7-11 Sep 2026 [5]. Outside the BE/FR/NL/DE scope, but it carries the most active academic-track CFP window in Europe right now:
- Industrial / Tools & Demos / Doctoral Symposium abstracts due 1 May 2026 (so: tomorrow) [6].
- Industrial papers, workshops, registered reports, tools-demos papers, IDEA-ARCH/ASISAS/CASA abstracts due 8 May 2026 [6].
- Workshop & co-located papers due 15 May 2026 [6].
- Open Science track due 19 Jun, Journal First due 26 Jun 2026 [6].
If your goal is “publish architecture work in 2026 with reasonable European reach”, ECSA’s industrial track at 8 May is the realistic window.
Wider European / global venues (for completeness)
| Conference | Country | Dates | Notes |
|---|---|---|---|
| QCon London 2026 [20] | UK | Mar 16-19, 2026 (past) | 75+ speakers, 15 curated tracks; peer-invited, no public CFP |
| GOTO Copenhagen 2026 [22] | DK | Sep 28 - Oct 2, 2026 | Closest GOTO to BE/NL audience; CFP windows are usually summer |
| ECSA 2026 [5] | IT | Sep 7-11, 2026 | Academic; multiple tracks open through Jun 2026 |
| ArchConf 2026 [21] | US (FL) | Dec 7-10, 2026 | Practitioner; software architecture + GenAI + microservices |
| Devoxx UK / SDD / API Conf / Craft / Codemotion [25] | UK / HU / ES | May–Jun 2026 | Architecture-adjacent; see dev.events for full European calendar (86 entries) |
How to pick
- Want to submit a talk this week and have it land in 2026? → ECSA industrial abstracts (May 1) [6] or Code BEAM Europe (May 31) [14] if you work in BEAM, or Techorama NL (May 29) [17] for general practitioner content. All three pay travel for accepted speakers (ECSA at speaker discretion; Techorama and Code BEAM explicitly).
- Want the highest-signal architecture CFP in DACH? → Wait one week, submit to iSAQB SAG when it opens 5 May [2]. 9 Jun deadline.
- Want the highest-signal practitioner audience in BE? → Devoxx Belgium, CFP opens 1 Jun [10]. The architecture track competes for slots; expect serious selection.
- Just want to attend? → DDD Europe (Antwerp, 10-12 Jun) [7] is the densest design-and-architecture event in BE/FR/NL/DE during the first half of 2026; ICSA Amsterdam (22-26 Jun) [3] immediately after if you want the research side; iSAQB SAG (Berlin, Nov 16-19) [1] and W-JAX (Munich, Nov 2-6) [13] carry the autumn.
