TL;DR. Within 30 km of Nuance [1] (Duffel — 15 km from Antwerp, 7 km from Mechelen, Brussels at 53 km is out [2]) ten major IT conferences run in 2026. Most end Thursday or Friday — the natural Saturday-Nuance bundles are Devoxx Belgium (5-9 Oct) [9], DDD Europe + BC TechDays (8-12 Jun) [6] [7], SmashingConf (12-15 Oct) [11] and CloudBrew (10-11 Dec) [13]. The only event already on a Saturday is dataMinds Saturday (21 Feb, free) [14] — same-day bundle with dinner.
What counts as “within 30 km”
Driving distances from Duffel centre [2] [3]:
| City | Road km | In ring? |
|---|---|---|
| Mechelen | ~10 | ✓ |
| Antwerp (centre) | ~15 | ✓ |
| Lier | ~9 | ✓ |
| Boom | ~12 | ✓ |
| Brussels | ~53 | ✗ |
| Ghent | ~70 | ✗ |
All venues in the calendar below sit in Antwerp city (Kinepolis, Antwerp Expo, Bourla, Queen Elisabeth Hall, Flanders MCC) or central Mechelen (Lamot, Thomas More) — every one is reachable in under 25 minutes by car from Nuance, less by train.

Cross-reference: the dev.events curated index lists the same 7 Antwerp + 3 Mechelen events plus DevFest/DevDay (Mons) and NG-BE (Ghent), all of which fall outside the 30 km ring [15].
Saturday-dinner pairing logic
Nuance dinner is the anchor. Conferences in Belgium run on weekdays — to bundle them, target the Saturday after a multi-day event so you stay one extra night.
| Saturday dinner | Pair with | Reasoning |
|---|---|---|
| Sat 21 Feb | dataMinds Saturday (same day) | Conference 08:45-18:00 in Mechelen → 19:00 dinner Duffel |
| Sat 16 May | Techorama (ends Wed 13 May) | Stay through weekend in Antwerp |
| Sat 13 Jun | DDD Europe / BC TechDays (both end Fri 12 Jun) | Densest week — three confs converge |
| Sat 26 Sep | BruCON (ends Fri 25 Sep) | After hacker-con wind-down in Mechelen |
| Sat 10 Oct | Devoxx (ends Fri 9 Oct) | The largest, most international option |
| Sat 17 Oct | SmashingConf / dataMinds Connect (end 14-15 Oct) | Two confs, one weekend |
| Sat 7 Nov | AutomationSTAR (ends Thu 5 Nov) | Long weekend buffer |
| Sat 12 Dec | CloudBrew (ends Fri 11 Dec) | Year-closer |
Recurring communities (no fixed 2026 schedule but worth tracking)
Smaller free events, mostly evening sessions — useful filler if your weekend wraps a weekday meetup.
- OWASP Belgium chapter — quarterly free meetups; 2026 sessions confirmed on Karel de Grote Hogeschool Groenplaats campus (Antwerp). Pentest themes, named speakers (Pentesterlabs, Toreon) [17].
- VISUG — Belgian Visual Studio User Group, evening .NET/Microsoft talks; 20-year anniversary in 2026 with a VISUG XL full-day [18].
- Belgian Kotlin User Group — confirmed Antwerp meetup Thu 4 Jun 2026, 18:30 [19].
- Fronteers BE — front-end community; meetup at Axxes Antwerp, Thu 21 May 2026, 18:00 [20].
- Antwerp School of AI — regular AI learning sessions, beginner-friendly [21].
- Belgian Java User Group — BeJUG, founded by Devoxx organiser Stephan Janssen; free JVM evening sessions year-round [22].
- Open Garage (Borsbeek, adjacent to Antwerp) — weekly Thursday electronics/maker night via Hackeragenda BE [23].
Venue cheat-sheet
| Venue | City | Used by | From Duffel |
|---|---|---|---|
| Kinepolis Antwerpen | Antwerp-Noord | Techorama, Devoxx, BC TechDays | ~22 km |
| Antwerp Expo | Antwerp-Berchem | Connect IT | ~10 km |
| Queen Elisabeth Hall | Antwerp Centraal | DDD Europe | ~16 km |
| The Bourla | Antwerp historic centre | SmashingConf | ~17 km |
| Flanders MCC | Antwerp Centraal | AutomationSTAR (A Room with a ZOO) | ~16 km |

Notes
- Lamot Mechelen is the single most-used venue in the 30 km ring — three majors per year (BruCON, dataMinds Connect, CloudBrew) plus regular smaller events. Worth knowing if you book a Mechelen hotel: walk from Lamot → train → Duffel is faster than driving back to a hotel in Antwerp.
- Brussels (53 km) and Ghent (70 km) carry their own conference scenes (EuroBSDCon, EuroSTAR, NG-BE) but fall outside the 30 km brief — not listed.
- The user-group landscape has thinned: Full Stack Antwerp wound down after 8 years; AntwerpJUG is marked inactive on Meetup. BeJUG and VISUG remain the active country-wide JVM/.NET communities [22] [18].
