Cloud Native Rejekts Europe 2025 aims to offer a stage to some of the great, but rejected talks from KubeCon Europe.

We welcome rejected proposals from KubeCon Europe or new ones that cover super fresh topics. We offer slots for 30min full-length talks and 5min lightning talks. While you may submit any talk that was rejected from KubeCon Europe, we are especially looking for talks about the following topics.

• core concepts
• open-source components + tooling
• CNCF projects
• user experiences
• security
• new developments + experiments (only those topics so new they could not be proposed for KubeCon)

If your proposal falls into one of these topics, then let's continue by clicking the button below.

Code of conduct

The Cloud Native Rejekts organizers strive to make this a friendly and safe event for everyone. By submitting your proposal you commit to abiding by the Code of Conduct.

Submission requirements

In general, you should assume that we follow the KubeCon guidelines for submission. Paramount should be that the talks cover open source cloud native topics.

Event Format

Cloud Native Rejekts Europe '25 is going to be held in person. If you have any questions about this, please let us know.

You can enter proposals until 2025-01-27 00:00 (GMT), 1 week, 3 days from now.
