This is what a standard is for. Each of these teams shipped a product without inventing new APIs and SDKs, so application code stays portable and teams remain free to move between them.
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.
"...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
Looking for your feature flag evaluations to be tied to your error and performance monitoring, take a look at @getsentry new OpenFeature Hooks: openfeature.dev/blog/sentry-…
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: openfeature.dev/blog/vercel-…
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
