Umbracokalaset is a full-day conference dedicated to Umbraco, the open-source .NET content management system, held in Stockholm, Sweden. The 2026 edition takes place on 20 October 2026 at Sveasalen on Sveavägen in central Stockholm, running from the morning through to the late afternoon with an optional evening activity afterwards. Presented by Swedish Umbraco agencies together with Umbraco and the local user group, the event builds on the success of the previous year's edition. The conference brings together Umbraco developers, agency teams, editors, and enthusiasts from across Sweden and the Nordic region. The programme consists of a schedule of talks from community speakers covering Umbraco development, .NET and C# practices, headless and composable architectures, and real-world implementation experience. The website and community are Swedish-language, giving the day a distinctly local character compared with the larger international Umbraco gatherings. Attendees gain practical knowledge from peers who build and run Umbraco sites every day, along with the chance to network with the Swedish Umbraco ecosystem in one place. For a CMS whose strength lies in its community, Umbracokalaset is an important regional fixture that keeps Nordic Umbraco practitioners connected to each other and to the wider open-source project.

A one-day event in Stockholm on the twentieth of October means short daylight and a real chance of cold rain, but also a city at its most atmospheric. Built across fourteen islands, the Swedish capital keeps water in view almost everywhere, and autumn brings low light across the harbour. The centre is compact, the transport punctual, and almost everyone speaks fluent English.
Arlanda (ARN) connects to Stockholm Central by the Arlanda Express in around 20 minutes, or by cheaper airport coaches in roughly 45 minutes. Bromma (BMA) is closer and handles some domestic and regional flights. The Tunnelbana metro is efficient and doubles as an art gallery, with many stations decorated by commissioned artists. Contactless cards work directly across metro, bus and tram.
Skip the taxi queue — pre-book a fixed-price airport transfer with Welcome Pickups. Exploring beyond the city? compare rental cars on Auto Europe.
Swedish mobile networks are fast and cover Stockholm comprehensively, including underground. An eSIM arranged before travel is the simplest approach in a country where cash has essentially disappeared and most transactions assume a working phone. Set up an eSIM with Airalo before you board and you're online the moment you land.
Vasa Museum. A seventeenth-century warship that sank on its maiden voyage and was raised almost intact in 1961, now displayed in a purpose-built hall on Djurgården. It is genuinely unlike anything else in Europe. Allow ninety minutes; reachable by tram or ferry. Tickets on Tiqets →
Gamla Stan. The medieval old town occupies its own island, with narrow lanes, ochre façades and the Royal Palace at its northern end. Compact enough to cross in fifteen minutes but worth an hour of wandering. Best in the late afternoon as the lights come on.
Fotografiska. A contemporary photography museum in a converted customs house on the Södermalm waterfront, open late into the evening — unusually useful for a conference schedule. The top-floor café has one of the best views back across the water to Gamla Stan. Tickets on Tiqets →
Södermalm. The southern island holds the city's independent shops, coffee bars and restaurants, with the Monteliusvägen path along its northern cliff giving a free panoramic view. A twenty-minute walk from the centre and the best area for an evening out.
How do I get from Arlanda to central Stockholm?
The Arlanda Express reaches Stockholm Central in about 20 minutes. Airport coaches take roughly 45 minutes at lower cost.
Do I need cash in Sweden?
Almost never. Sweden is close to cashless and cards or mobile payments are accepted everywhere, including on public transport.
How much daylight is there in late October?
Limited — expect sunrise well after seven and darkness by late afternoon. Plan any outdoor sightseeing for the middle of the day.
