GO Feature Flag

A release that ramps itself up 📈 Give your GO Feature Flag flag a progressiveRollout with a start and end date: traffic shifts gradually from the old variation to the new one in between, all automatic. https://gofeatureflag.org/docs/configure_flag/rollout-strategies/progressive?utm_source=bluesky

GO Feature Flag images on Docker Hub have passed 2.3 million pulls 🐳 Thank you to everyone running GO Feature Flag in their stack and CI! https://hub.docker.com/u/gofeatureflag

An A/B test that ends on its own? 🧪 Give your GO Feature Flag flag an experimentation block with start and end dates. It's only served in that window; outside it, everyone gets the default value. https://gofeatureflag.org/docs/configure_flag/rollout-strategies/experimentation?utm_source=bluesky

GO Feature Flag v1.57.1 is out. Using signed webhook notifications? Upgrade: overlapping notifications could go out with another one's signature. Each request now gets its own headers. Go is bumped to 1.26.10, which fixes Go CVEs. github.com/thomaspoignant/go-feature-flag/releases/tag/v1.57.1

Ship on Friday, launch on Monday ⏱️ In GO Feature Flag, add a scheduledRollout to your flag: dated steps that can change any field, like internal users tomorrow and your beta segment four days later. https://gofeatureflag.org/docs/configure_flag/rollout-strategies/scheduled?utm_source=bluesky

GO Feature Flag v1.57.0 is out 🚀 The Helm chart can now run the relay proxy as non-root, its PodDisruptionBudget targets the right pods, API keys are redacted from access logs, and exporters flush on shutdown. https://github.com/thomaspoignant/go-feature-flag/releases/tag/v1.57.0

Welcome Planton to the GO Feature Flag adopters list 🎉 They run GOFF on Kubernetes, picking it for the upstream Helm chart, readable YAML flag files, and flags served through the Kubernetes API. Their write-up: https://planton.ai/blog/feature-flags-opentelemetry-moment

Planton picked GO Feature Flag for its Kubernetes setup: an upstream Helm chart, readable YAML, and flags read straight from the Kubernetes API. A flag flip takes 26s end to end, with zero restarts. 🚀 Great write-up by Swarup Donepudi 👇 https://planton.ai/blog/feature-flags-opentelemetry-moment

"Is this feature actually live for this customer?" Three answers at DataGalaxy: a SQL table, a build-time env var, an ingress rule nobody had touched in months. Tom Flenner on replacing all of it with @openfeature.dev + @gofeatureflag.org : gofeatureflag.org/blog/datagal...

Some big updates for OpenFeature so far this year — @datadoghq.com, @vercel.com, @cloudflare.social, @developers.google.com, @mixpanel.com, @octopusdeploy.bsky.social all launched feature flag services supporting the standard. openfeature.dev/blog/openfea...

We have new stickers 🧡 And yes you can test in production ! But only if you have a feature flag 🙌

Enjoy the devoxx talk this week

🚀 Big news for @GoFeatureFlag.org users! We just shipped in-process evaluation for our OprnFeature server providers (Go, Java, .NET, Python, JS/TS). → No network call per flag check → Lower latency → Full observability still intact Read the full post 👇 gofeatureflag.org/blog/2026/03...

GO Feature Flag v1.50.0 is here to fix that. 🚀 We just dropped a massive update focused on scale and observability. Better performance. Zero downtime. Full visibility. 👇 github.com/thomaspoigna...

🚀 Organize your feature flags like never before 🚀 We are happy to launch the concept of flag sets into GO Feature Flag. What is a flag set 🤔? It is a isolated group of feature flags and it means that GO Feature Flag is now multi-tenant 🙌🎉 gofeatureflag.org/blog/2025/09...

Adopting feature flags and A/B testing seems to be more and more accurate in the age of AI development. source: newsletter.pragmaticengineer.com/p/measuring-...

We are continuing working on in process providers for server SDKs,. Java ☕️ is almost done and .NET is on his way. This is a really exciting step for GO Feature Flag 🙌

Today I was talking with some @gofeatureflag.org users and discovered that they have thousands feature flags in production. They have built a full Flag as a service system for there 150+ teams using GOFF. This is the kind of things that made my day.

If you are interested to adopt GO Feature Flag in your company and need some demo. You can now book it directly yourself here : calendly.com/thomas-poign...

I have a ton of idea, but not sure how to prioritize them. Please help me to understand what is the most important for you: 1. In process evaluation for server providers. 2. Flag management system UI 3. Support tracking in all the SDKs 4. Flag sets Let me know what do you want to see 😅

Check the latest news of @openfeature.dev presented at Kubecon !

*43 days until KubeCon & a bit of OpenFeature a day Nr. 1* Let's tackle the most obvious question to start this with: What is OpenFeature? A standardization of feature flagging. It's an open-source project, part of the CNCF landscape & and standardizes the look and feel of feature flags.

OpenFeature Summit talk schedule lookin' 🔥🔥🔥 See us at the summit, as well as at KubeCon EU!

I love this new line in the website. If you want to tell us that you are using GO Feature Flag please add your self to the adopters list github.com/thomaspoigna...

I am working on the @gofeatureflag.org .NET provider to refresh it and to support metadata. That was really fun to change language once more. #dotnet #featureflag github.com/open-feature...

🚚 We have launched an awesome new feature if you are using exporters. Check how to attach your own information to the evaluation data events in our latest blogpost. gofeatureflag.org/blog/2025/01...

We’ve just released the brand new rewrite of the documentation. ✏️ It should be even simpler than before to start with GO Feature Flag 💪 And to find advanced usage too. You like it ? Or you hate it ? Give us feedback 🙏🏻 docs.gofeatureflag.org

📣 Hey Android users, you can now use evaluation metadata in your application with the release of the new provider 🙌 This enable a ton of new use cases to know more about your flag evaluation !!!

If you weren't able to attend KubeCon / OpenFeature Summit last month, check out our latest blog post for some amazing highlights (and some news about the latest SDK features)!
