GrowthBook 2.0 is here! Learn about the developer focused improvements in 2.0, including Typesafe SDK, REST API, and more!
GrowthBook 2.0 is finally here, and this new version is so packed full of feature announcements, we had to split it up over 3 days. Today we’re focusing on Developers and the work we’ve been doing behind the scenes to enable a world class developer experience.
Typesafe SDK
GrowthBook is pleased to offer the first ever fully typesafe feature flag SDK for Typescript. Now you can detect typos and bugs in your feature flag checks during compile time. To make this possible, we built a GrowthBook CLI that can auto-generate type definitions based on features defined in your GrowthBook account. You can read more about this feature and get details instructions for setting it up on our engineering blog — https://blog.growthbook.io/fully-typesafe-sdk
Instant Feature Releases
After the success of our self-hosted GrowthBook Proxy release in version 1.9, we’re excited to bring the same benefits to our Pro and Enterprise customers on GrowthBook Cloud. Over the next several weeks, we will enable instant feature rollouts on these accounts. When enabled, feature changes you make in the GrowthBook UI will be released to all of your users in under a second. Read more about this feature and how we’re scaling it to billions of feature requests on our blog — https://blog.growthbook.io/faster-feature-releases-on-growthbook-cloud
REST API
We have been hard at work expanding our REST API, adding over 20 new endpoints and a brand new documentation site: https://docs.growthbook.io/api. We’re super excited about all of the use cases this unlocks, including the ability to sync experiment results to your data warehouse, one of our most requested features! Read more about the new endpoints and changes on our blog — https://blog.growthbook.io/new-rest-apis
More Code Examples
We’ve improved our example repository to include even more examples on how you can integrate GrowthBook with your code. You can check out the examples repo here: https://github.com/growthbook/examples
Other Developer Focused Features and Improvements
- Improved GoLang documentation and examples

Tomorrow we’ll turn our attention towards the many data scientists and analysts using GrowthBook every day. Stay tuned!
