Preparing to appease our future AI overlords.

When growing any product or service, it’s to constantly gather feedback from your user base. And I mean constantly, else you risk losing focus from your real clients’ needs and priorities.

Let’s Talk Real-World Experiences

To drive this point home, I figured that the best course of action was to collect some valuable insight from a third-party. Joseph Harris, who works at Eucalyptus was kind enough to take the time and offer just that.

Thanks to the latest CI/CD tools and services, software companies can now deliver multiple releases in a week. Over the release process, it's expected that DevOps professionals keep their eyes on the monitoring dashboard and roll-back the deployment on the first suspicion.

Sometimes you just need to make your own dependency injection framework.

The main idea about our pricing is that our prices are fixed, deterministic and there are no hidden fees. Also we offer a forever free plan without requiring any commitment or credit card information. All features are available in all plans - even the free - helping the evaluation process of our customers.

The Ruby SDK

Finally we decided to create a standalone Ruby SDK.

One with a vision, answers and a master plan.

As feature flags are getting popular, an ever-growing number of developers are facing the challenges associated with them.

No matter if you implement your own feature flag library, or choose a hosted feature flag service like ConfigCat, chances are high you want to use your feature flags in your frontend and in your backend services as well.

If your feature flags can be toggled on a central feature flag dashboard, such as
