Feature flags help teams release software with more control. You can roll out features gradually, target specific users, run safer production releases, and turn risky functionality off without redeploying your application.

But once feature flags become part of your release workflow, another question comes up: should your application code depend directly on one feature flag vendor's SDK?

That is where OpenFeature can help.

In this guide, we'll look at what OpenFeature is, how it works with ConfigCat, and how to use the ConfigCat OpenFeature Provider for Node.js in a simple Express API.

Before the open source movement, software programs were 'closed source,' meaning only software developers employed by the company could access and modify them. Outsiders were kept out through non-disclosure agreements and licenses. This exclusivity motivated the creation of the open-source movement, aiming to preserve the freedom to modify and distribute software through publicly accessible code. Today, many commercial companies actively participate in the open-source ecosystem, maintaining software that is open to the public for access and contributions. One such company supporting this effort is ConfigCat.

In the context of SaaS applications, having a tool that allows you to control different features and flag certain users is critical, given the uniqueness of their needs and the instability of new releases.

This is where the ConfigCat Elixir SDK's tale begins. This is the simplified narrative of a great open-source SDK, driven by highly-professional folks from three different companies, as told by one of its creators.

Sit down, relax, and let me tell you an awesome story about the little country that could. A country that's unapologetically close to my heart. In case the title hasn't already given it away by now, I'm of course talking about the wonderful nation of Iceland.
