Project Lightning Talk + ContribFest + Maintainer Track: KubeCon + CloudNativeCon Europe 2026

PROJECT LIGHTNING TALKS - MONDAY, 23 MARCH

Audience: Attendees (Beginner) 

Projects will have the opportunity to deliver lightning talks lasting 5-minutes during KubeCon + CloudNativeCon. This platform offers projects the chance to showcase their recent updates, features, and other highlights to their peers. The project lightning talks will be included in the conference schedule and are based on availability.

Because these talks are centered on the project rather than any individual speaker, complimentary passes are not provided. If you don’t already have a pass and are unable to secure funding to attend, we recommend applying for a scholarship. Alternatively, if you're unable to attend, we would still consider the talk if another project representative is available to present on your behalf.

A maximum of 1 speaker is allowed per Project Lightning Talk. Please do not submit more.
