OPEN SOURCEOBSERVABILITYDAY 2027
After three years of meeting online, we're taking OSOD into a room. One day, one stage, and the whole open source observability community together in Gent, Belgium.
Doors open in Gent
The Community,
In The Same Room
After three years of online editions, Open Source Observability Day leaves the browser tab behind for 2027. We're bringing the conference to Gent for a single in-person day of talks, demos and conversation about the open source tools behind modern observability. Same community, same open spirit — now with coffee breaks you can actually have a conversation in.
Open Source, Up Close
Talks from the people building the tools — not a product pitch in sight.
Real Conversations
Long breaks and a proper hallway track. The best part of an offline conference is the room itself.
Field-Tested Lessons
Case studies from SREs and platform teams you can take back to your own systems.
A City Worth The Trip
Canals, medieval streets, coffee and good beer — Gent makes the trip an easy sell.
Meet Us In Gent
For our first in-person edition we've picked a city that's easy to reach and hard to leave: Gent, in the heart of Flanders. Compact, walkable, and full of places to carry the conversation on after the last talk.
HOGENT Schoonmeersen Campus
One stage inside HOGENT's Schoonmeersen campus in Gent, with room for talks, breaks and the hallway track. Room details and the full address arrive with the programme.
View on mapBy train
Gent-Sint-Pieters is the city's main station, with direct services from Brussels (about 30 minutes) and Antwerp — and the Schoonmeersen campus is a short walk from there.
By air
Brussels Airport (BRU) is the closest hub — trains from the terminal reach Gent in roughly an hour.
Where to stay
Plenty of hotels sit around the historic centre. We'll share a recommended shortlist with ticket holders.
February in Gent
Expect around 5°C and a fair chance of rain. A warm coat and comfortable shoes are the whole packing list.

The stage is open
Speakers for 2027 are not announced yet — because we're still taking submissions. If you have a story about tracing, metrics, logs, eBPF, Prometheus or the unglamorous plumbing behind them, we'd love to hear it.
Reserve your place
Free to attend, but the room is finite. Register and we'll send your confirmation straight away.
Speakers To Be Announced
