DevDays Europe 2027
6 Leading European Software Development Conferences Compared: 2026–2027
Compare six prominent English-language software development conferences in Europe by date, learning format, published scale, ticket price and the audience each event serves best.
Quick Answer
There is no single best conference for every developer. Start with the experience you want—very large event, specialist community, workshops, senior-level case studies, curated engineering talks or broad access for a mixed team—then use the six recommendations below.
- WeAreDevelopers World Congress Best for a very large developer gathering, many stages, a major technology expo and career or vendor discovery.
- Devoxx Belgium Best for a large community-led developer week with Java, JVM, AI, cloud-native and hands-on depth.
- NDC Oslo Best for attendees who want two full workshop days followed by a broad three-day, multi-technology conference.
- QCon London Best for senior developers, architects and technical leaders seeking production lessons from early-adopter engineering teams.
- GOTO Copenhagen Best for a curated, speaker-led programme spanning architecture, programming, AI, security, teams and software delivery.
- DevDays Europe Best for a broad onsite programme and mixed engineering teams that value software development, DevOps and cybersecurity access under one ticket.
All six publish their current programme in English, welcome international participants and have an officially confirmed European edition in 2026 or 2027. Their published scale figures measure different things, so this page labels event totals, series totals, proposal data and shared-event figures instead of treating them as one attendance league table.

Why These Six European Software Development Conferences Were Selected
These are six leading conferences, not a claim that one objective ranking can identify Europe’s six “best.” They were selected because they combine large published reach, an established international reputation, programme depth or a distinctive position in the European developer conference market.
- Largest published reach: WeAreDevelopers reports 15,000+ builders, 500+ speakers and a large expo for one Berlin edition.
- Established developer community: Devoxx is a long-running international series, and its Belgian edition publishes a five-day, ten-room programme with particularly strong Java roots.
- Training and programme breadth: NDC Oslo combines two workshop days with three conference days and covers many development stacks rather than one language, with 2,700+ participants expected.
- Senior engineering focus: QCon is designed around production experience from innovator and early-adopter engineering organisations.
- Curated all-round learning: GOTO Copenhagen combines recognised practitioners with broad software-engineering topics and optional masterclasses.
- Broad multi-conference access: DevDays Europe is included both for its international developer programme and because readers on the organiser’s website need a transparent comparison with larger alternatives.
- International accessibility: all six publish their current programme in English and welcome participants beyond a single local-language community.
Published audience figures are not used as a simple league table. WeAreDevelopers reports one congress, Devoxx publishes detailed schedule and CFP figures plus a wider series total, GOTO publishes an onsite sponsor audience, and DevDays reports totals for three co-located programmes. Each scope is stated beside the number.
DevDays Europe vs Other Leading Software Development Conferences
These head-to-head comparisons focus on the practical choice: event scale, technical specialisation, workshop time, seniority, expo access and whether one ticket serves several roles on the same engineering team.
DevDays Europe vs WeAreDevelopers World Congress
Choose WeAreDevelopers when scale is a priority: it publishes by far the largest audience, speaker, stage and expo figures in this comparison. Choose DevDays Europe for a smaller learning environment, three full conference days, an optional full-day workshop and easier movement between software development, DevOps and cybersecurity sessions.
DevDays Europe vs Devoxx Belgium
Choose Devoxx Belgium for a large community event with deep Java and JVM roots, ten rooms and several formats ranging from conference talks to labs and Deep Dives. Choose DevDays Europe for a more language-independent programme and one pass that also covers dedicated DevOps, cloud, platform-engineering and cybersecurity tracks.
DevDays Europe vs NDC Oslo
NDC Oslo is the stronger choice when two full workshop days and a five-day all-access learning week justify the higher ticket price. DevDays Europe uses one workshop day and three conference days, has a lower published entry price and gives mixed teams access to three co-located conference programmes.
DevDays Europe vs QCon London
QCon London is aimed more specifically at senior developers, architects and leaders evaluating emerging practices and production architecture. DevDays Europe serves a wider experience range and a broader mix of development, operations and security roles, with workshops and a larger number of parallel subject areas.
DevDays Europe vs GOTO Copenhagen
GOTO Copenhagen is the better fit when a carefully selected speaker programme and optional deep masterclasses are the main priorities. DevDays Europe offers a larger shared session pool across three conference brands and is better suited when colleagues in development, platform, DevOps and security want useful schedules under the same ticket.
DevDays Europe Audience and Team Fit
These first-party figures show the audience DevDays Europe is designed to bring together. They are organiser-reported and should be read as directional because the public page does not state the edition year, sample size or collection method.
| Audience dimension | Organiser-reported distribution |
|---|---|
| Professional roles | Software development and engineering 70%; executive and management 10%; IT operations and security 7%; data, analysis and quality 4%; other roles 9% |
| Experience levels | Senior 52%; mid-level 28%; junior 10%; entry level 6%; executive 4% |
| Regions | Northern Europe 59%; Western Europe 15%; Central and Eastern Europe 13%; Southern Europe 8%; outside Europe 5% |

How to Choose the Right European Software Development Conference
Start with the engineering problem or skill you want to improve, then compare the learning format and total trip cost—not only the conference name or headline attendance number.
- Topic fit: decide whether you need broad software development coverage or deeper focus on Java, architecture, AI, cloud-native engineering, DevOps, security or technical leadership.
- Experience level: check whether the programme is aimed at a broad developer audience or primarily at senior engineers and architects.
- Learning format: compare conference talks, full-day workshops, labs, certification, expo time, recordings and peer discussion.
- Team fit: confirm that developers, architects, platform engineers, security specialists and managers can all build relevant schedules.
- Event environment: choose between a very large congress and expo, a specialist senior-engineering event, a community conference or a smaller multi-track setting.
- Total cost: include VAT, travel, accommodation, workshops, pass duration, catering and whether recordings are included.
- Current information: recheck the official programme and ticket page before booking because prices, speakers and session totals can change.
Research Method and Official Sources
How the Facts Were Checked
Dates, locations, formats, programme scope, published scale and prices were checked on official organiser or organiser-linked registration pages on . All six events publish their current programme in English and address an international professional audience. Search results and conference directories were used only to discover candidates, not as the final evidence for the table.
“Best suited to” statements are editorial recommendations based on each published programme and format; they are not claims made by the other organisers. The page should be updated whenever an organiser changes a date, price stage or programme and reviewed in full no later than .
How Prices Were Compared
A full standard conference pass was used where the organiser published one clearly. Workshop, certification, group, student, startup and eligibility-limited options are labelled rather than treated as equivalent. Original currencies were retained because exchange rates change, and the table does not pretend that different pass lengths, meals, recordings or VAT rules are identical.
