Direct peers

• ReactiveConf: ReactiveConf is a European developer conference focused on modern web and software development with strong AI content. It is a directly comparable developer conference in format and audience, though larger and based in Czechia.
• JSConf EU: JSConf EU is a single-topic JavaScript developer conference held in Europe with a community-organized ethos. Its single-day/single-topic format, community-driven speaker curation, and developer audience make it a strong format peer to DevDay's Dev track.
• NDC Conferences: NDC runs developer-focused conferences (NDC Oslo, London, Sydney, etc.) covering software development practices and architecture. Its single-day-to-multi-day track structure and practitioner-first content approach closely mirrors DevDay's developer track model.
• dotConferences: dotConferences (dotJS, dotSwift, dotAI, etc.) runs single-day, multi-track conferences in Paris for developers across specific topics including AI. The single-day format, topic-specific tracks, and developer audience make it a strong format peer to DevDay.
• Devoxx: Devoxx is one of the largest developer conferences in Europe, founded in Belgium and run annually in Antwerp and other cities. Like DevDay, it targets Java/Polyglot developers and tech professionals with multiple tracks and hands-on content, making it the most direct Belgian/European peer in scope and audience.

Emerging players

• Agile Belgium / Journée Agile: Journée Agile is an existing DevDay sponsor and runs its own Belgian agile community events. It overlaps with DevDay in audience (tech professionals, leaders) and topic (modern delivery practices), making it an adjacent peer.

Regional players

• Paris Web: Paris Web is a French-language web and technology conference focused on web developers, designers and digital professionals. Like DevDay, it is a community-organized regional event targeting developers, but it operates in France rather than Belgium.

Broad incumbents

• KubeCon + CloudNativeCon (CNCF): KubeCon is the flagship conference for the Cloud Native Computing Foundation, targeting developers and platform engineers. It is much larger and globally distributed, but its developer/operator audience and AI-adjacent infrastructure focus overlap with parts of DevDay's Dev and AI tracks.
• O'Reilly Velocity / O'Reilly Conferences: O'Reilly runs and supports multiple technology conferences (Velocity, OSCON, Strata) targeting developers and technical practitioners. It is a much larger incumbent in the same conference-for-developers category, with broader topic coverage and global reach.
• The Next Web (TNW) Conference: TNW Conference is a large Amsterdam-based tech event covering startups, development, and emerging tech. It targets a broader tech-leadership audience but overlaps with DevDay's leadership track and European geography.
