What a week at KubeCon + CloudNativeCon EU 2026 in Amsterdam. Huge thanks to everyone who came to our talks, stopped by the OpenFeature booth, asked questions, or just said hi. Your feedback and stories keep the project moving forward.

Some tools force you to learn a complicated API and require constant maintenance.

Other tools... just work, and that's why it's easy to overlook them.

@OpenFeature is one of those tools.

Do I use it daily? Yes.
Do I ever have to think about it? No.

A great way to get started with feature flags!

Really, an exemplary postmortem by @googlecloud: https://t.co/oHQzcz6Kx5

[OpenFeature @OpenFeature]

"...did not have appropriate error handling nor was it feature flag protected..."

"...We will enforce all changes to critical binaries to be feature flag protected and disabled by default..."

There's also a REALLY interesting case study from eBay's @OpenFeature adoption that's well worth reading.
- Rolling out a platform to 300 teams
- Billions of flag evaluations made per day
- 2500+ experiments behind flags every year

Happy to share that OpenFeature Node.js Providers are now supported by the open-source @vercel Flags SDK for Next.js and SvelteKit. Check out the details: https://t.co/hlTRzj3ujw

[Dominik Ferber @dferber90]

You can now use the Flags SDK with any OpenFeature provider

This marks an important milestone, as it is now way easier to get started with flags

We also added a top-level section to our docs highlighting available providers

OpenFeature makes Feature Flags easy in any programming language. In this video, we’ll break down how it works, set it up in a React app with a Python backend, and integrate it with OpenTelemetry for monitoring. Perfect for stress-free releases and A/B testing!
