TL;DR. Almost the entire architecture/DDD conference circuit closed its CFP over the summer. Act now on DDD Europe 2027 (Amsterdam, deadline 16 Jan 2027, still 4 months out, best architecture/DDD fit, pays travel+lodging+childcare) [3]. The one that closes soonest is EuroSTAR 2027 (Copenhagen, deadline 30 Sep 2026 — 10 days away) [1], a good fit for TDD/AI-assisted-testing talks. Craft Conference 2027 (Budapest) shows a live submission form but its own FAQ contradicts that — verify before writing a talk for it [4][5]. Everything else architecture-flavored (iSAQB Software Architecture Gathering, KanDDDinsky, Øredev, Devoxx Belgium, NDC London) has already closed for this cycle; Devoxx France opens “at year-end” 2026 [14] and is worth calendaring.
1. Open now
Sorted by CFP deadline, soonest first. Verified by fetching each CFP/event page directly on 20 Sep 2026.
| Conference | Dates & city | CFP deadline | Submit | Formats | Compensation | Fit |
|---|---|---|---|---|---|---|
| EuroSTAR 2027 | 11–14 May 2027 · Copenhagen, Denmark [2] | 30 Sep 2026 (timezone not stated) [1] | Oxford Abstracts [1] | Track Talk (30+15min Q&A), Tutorial (half/full day), Deep Dive (2×45min) [1] | Not stated beyond a “speaker success programme” — no explicit travel/honorarium [1] | Theme is “Sharpening the Craft” — strong slot for TDD, quality engineering, or AI-assisted-testing talks; not architecture-specific but topically adjacent. |
| Craft Conference 2027 | 3–4 Jun 2027 · Budapest, Hungary [4] | ⚠ Ambiguous — a live Google-Form “Join as a speaker” link is on the site [4], but the FAQ separately states the page currently shows CFP as closed and that it “is usually open… until November each year” with rolling review [5] | Speaker form [4] | Not published on the speakers page [4] | Not published [4] | Broad polyglot craft/architecture audience (2000+ attendees); reasonable stage for design-patterns or AI-assisted-development talks — confirm CFP is truly live before drafting. |
| DDD Europe 2027 | 3–4 Jun 2027 (workshops 31 May–2 Jun) · Amsterdam, Netherlands [3] | 16 Jan 2027 (timezone not stated) [3] | Sessionize [3] | Talk (50min), Interactive Talk (2h, audience dialogue), Hands-on Lab (2h, ≥50% practical) [3] | Travel, accommodation, and professional child care, plus conference access [3] | Best architecture/DDD fit on this list; targets “experienced engineers and architects” and explicitly wants AI-assisted-DDD angles (ubiquitous language with AI, RAG × bounded contexts) [3]. |
2. Opening soon / expected
Not open yet, but the window falls inside or just past the ~8-week horizon (mid-November 2026), or the pattern is well-established enough to plan around.
| Conference | Next edition | Expected CFP window | Note |
|---|---|---|---|
| Devoxx France | 7–9 Apr 2027 · Paris (15th edition) | “Opens at year-end” 2026 per the official FAQ — likely Nov–Dec 2026 [14] | Big polyglot conference, 9 tracks, ~4,500 attendees/day; historically takes architecture and AI-in-engineering talks. |
| Voxxed Days Luxembourg | Edition TBA | The org’s own CFP page currently still shows the 2026 cycle (closed 29 Mar 2026 for the June 2026 event); a 2027 date is not yet published there [16] | Smaller single-track Devoxx-family event, good for a first international submission. |
| Devoxx Poland | Edition TBA (2026 was 17–19 Jun, Kraków) | Historically opens January, closes late February [22] | Outside the 8-week window but worth calendaring now — CFP volume is high (multi-track). |
| WeAreDevelopers World Congress | 14–16 Jul 2027 · Berlin | Not yet announced [19] | Largest polyglot congress in Europe (15,000+ attendees); explicitly recruits AI-builder content, good target for an AI-assisted-development session. |
| XP 2027 | 31 May–3 Jun 2027 · Tampere, Finland | “Announced soon,” no date yet [20] | Academic/practitioner Agile conference, 2027 theme is explicitly “Agile in the Era of AI” — unusually good fit for AI-assisted-TDD material if you’re open to an academic-style submission track. |
| Agile Testing Days | Nov 2026 edition already closed | 2027 window not yet announced; 2026 opened 30 Jan–29 Mar [18] | TDD/quality-culture fit; put a reminder for late January 2027. |
| Devoxx UK | Uncertain | No 2027 edition confirmed — organizers are polling community support after 2026 “wrapped” [21] | Don’t plan around this one until it’s confirmed. |
3. Already closed
Notable 2026/2027 editions whose CFP has passed, so you don’t need to re-check them.
| Conference | Edition | Dates & city | CFP closed |

| W-JAX | 2026 | 2–6 Nov 2026 · Munich, Germany [12] | ⚠ No CFP page found; presumed closed given the event is ~6 weeks out. |
| Devoxx Morocco | 2026 | ~4–5 Nov 2026 · Casablanca, Morocco (date per third-party listings; official page still shows the 2025 edition) [15] | ⚠ Deadline not published on the official page; presumed closed given event proximity. |
| NDC London | 2027 | 25–29 Jan 2027 · London, UK [17] | 30 Aug 2026, 23:59 CET [17] — not architecture-specific, but strong general .NET/cloud/AI fit; travel/accommodation covered for non-local speakers. |
| GOTO Copenhagen | 2026 | 28 Sep–2 Oct 2026 · Copenhagen, Denmark [9] | No open CFP visible; event starts in 8 days. |
| GOTO Aarhus | — | Last confirmed edition was 2024; no 2026/2027 edition found | Appears discontinued or folded into GOTO Copenhagen [10]. |
Notes on scope
- QCon London does not run an open CFP — speakers are invited by track hosts under a Programming Committee model, so there’s nothing to submit to.
- NewCrafts is on a break in 2026; no 2027 dates or CFP found.
- SoCraTes (Germany/UK/Switzerland/Crete/Belgium editions) is an open-space unconference — there is no call for papers; participation is via ticket registration, so it’s excluded from the tables above by design.
- Not independently re-verified for this run (would need dedicated fetches): GOTO Amsterdam’s next edition, JAX Mainz 2027, GeeCON, Topconf. None showed a live 2026/2027 CFP in preliminary checks.
