GrowthBook

We’re pleased to announce GrowthBook 3.0!  This release has a lot of huge new features which you can read about on our blog: https://lnkd.in/eUp4jQ66 or see some highlights below. Edge SDKs We’ve developed SDKs that seamlessly integrate with your CDN Edge, allowing you to conduct experiments directly on edge workers. With dedicated SDKs for Cloudflare Workers, Lambda@Edge, Fastly Compute, and others, you can now run client-side tests (including visual editor tests, URL redirects, and feature flags) without any of the typical issues they have, including ad blocks and flickering. Explore the documentation here: https://lnkd.in/ezDEB4PY. Bayesian Priors and CUPED We reworked our Bayesian statistics engine to support increased accuracy, support for priors, and CUPED variance reduction. You can read more about the Bayesian changes on our blog: https://lnkd.in/eZm6SqJy Custom Roles A long-awaited enterprise feature, you can now define custom roles with exactly what permissions they can or cannot have and then assign those roles to users or teams. This feature empowers you to tailor roles to your team's specific needs. View the Custom Role docs for more details: https://lnkd.in/eJGTC9ZM OpenFeature Support We’re excited to join the OpenFeature ecosystem with an official GrowthBook Provider!  This initial release adds support for the Web and React SDKs, but we plan to add providers for all supported languages soon, so stay tuned! Experiment Slack/Discord Alerts We’ve added experiment warning alerts for when there are errors or warnings with your experiments JSON Feature Flag Editor You can now define exactly what fields you want to pass with the feature flags, resulting in a user-friendly UI with full validation. New Next.js Examples We’ve updated our Next.js examples to include all the new rendering strategies available with the Next 14 App Router.  We show how to use GrowthBook inside of React Server Components, how to integrate with the built-in fetch cache (with webhook revalidation), plus a powerful hybrid strategy that lets you do client-side feature flagging without any client-side network requests! Check out the repo: https://lnkd.in/eJh5Hxzv SDK Updates The GrowthBook team and community have been hard at work creating and improving our SDKs. We’ve added a new React Native SDK, completely refreshed the Elixir, GoLang, and C# SDKs, and improved the Java, Python, Ruby, JS, React, Flutter, Swift, and Kotlin SDKs.

We’re proud to announce the release of GrowthBook 2.9, with many highly requested features, including Feature Flag Approvals, URL Redirect Testing, and Quantile Metrics. More details below or on our blog: https://lnkd.in/ecJf5Bzk URL Redirect Testing One of the most common use cases for A/B testing on the web is to compare two versions of a page, hosted on different URLs. With this update, GrowthBook has native support for URL redirect tests. All you need on your site is the latest version of our JavaScript, React, or new HTML Script Tag SDK Quantile Metrics (Median, P99, and more) We’re proud to announce that GrowthBook is the first experimentation platform to fully support Quantile metrics. You can now report on things like P99 Latency, Median purchase price, and even use quantiles for decomposition deep dives! Feature Flag Approvals GrowthBook now supports advanced approval flows for feature flag changes. It behaves similarly to GitHub - make a change in a new draft revision, mark it as “ready to review”, another person on your team reviews it and decides whether to approve, request changes, or just leave a comment. Project-scoped Attributes and Environments Now, you can restrict attributes and environments to a subset of your projects, simplifying the GrowthBook UI and reducing the chance for typos and mistakes. Plus, when combined with project-scoped roles, you now have fine-grained control over exactly who is able to manage which attributes and environments. New HTML Script Tag SDK There’s a brand new GrowthBook SDK available, perfect for all low-code websites (Webflow, Shopify, Wordpress, and more). All you have to do is add a single `<script>` tag to your website and you’ll get support for our Visual Editor, new URL Redirect tests (see above), and even Feature Flags!  No configuration is required (although there are lots of knobs and switches for those that want them). New and Improved Webhooks with Slack/Discord Support We’ve revamped our event webhooks with more powerful filtering. Want to trigger a webhook for all feature flags that change in `production` with the tag “important”? You can do that! To make integration easier, there’s a new Formatter option to automatically render the webhook in a format that Slack or Discord understands.

We have just released GrowthBook version 2.8. This release includes prerequisite flags, feature flag code references, version-controlled metric support, no-access user roles and more. Read more about the changes below or on our blog: https://lnkd.in/eX5_7CKj Prerequisite flags With Prerequisites, you can group together related feature flags and describe complex relationships between them. For example, you can have a bunch of features that all reference a `release-2.8` parent flag as a prerequisite. The child features will only be enabled when the parent flag evaluates to 'true.' This also unlocks a bunch of more advanced use cases, which you can read on our blog. Official (Version Controlled) Metrics It’s not uncommon for large organizations to have hundreds or thousands of experimentation metrics. These are often a mix of “Official” metrics (widely used and vetted by the data team) and Ad-Hoc metrics (one-off, created by a product team, etc.). GrowthBook 2.8 introduces a brand new workflow that can make this distinction clearer and lead to more trustworthy experimentation. You can now store your Official Metric definitions as code in a version control system like GitHub and changes can be automatically synced to your GrowthBook account. Feature Code References In version 2.6 we released stale feature flag detection. Now with Code Refs you to keep track of feature flag usage by showing you exactly where each flag is used in your code. “No Access” Role In previous versions, the lowest role you could grant someone in your GrowthBook account was “readonly”. This meant that every user you invited to your organization could, at the very least, see every single feature flag, experiment, etc., in your account. GrowthBook 2.8 introduces a new role called “No Access”. As the name suggests, this is even lower than “readonly” and essentially grants no permissions whatsoever. When combined with project-scoped roles, this becomes super powerful. For example, grant someone a global role of “No Access” and then override this with a more permissive role for specific projects. Webhooks for SDK Connections Every SDK Connection in GrowthBook gets a dedicated API endpoint that returns a JSON payload of all included feature flags and experiments. You can now attach Webhooks to an SDK Connection so you can be alerted any time this payload changes. 

The data science team at the Los Angeles Times demonstrates the capability of GrowthBook to run faster experiments. By using CUPED, they show they can reduce the required sample size by a remarkable 85%. Read the full article here: https://lnkd.in/ge48anUN

Alto Pharmacy has recently chosen GrowthBook as its experimentation platform, selecting it over competitors such as Split, Amplitude, and LaunchDarkly. The reason behind their decision was GrowthBook's strong commitment to privacy, ensuring the protection of Personally Identifiable Information (PII) and Protected Health Information (PHI) in compliance with HIPPA regulations. Moreover, GrowthBook's self-hosting capability and open-source nature were also important factors. For more information on this decision, you can read Alto's blog post: https://lnkd.in/gA-Mqr9p Alto is America's leading digital pharmacy, focusing on helping people live healthier by making the prescription experience easier. To date, Alto has fulfilled more than three million prescriptions and expanded to twelve markets. #abtesting #featureflags #opensource

GrowthBook has just launched version 2.5, which may be our biggest release yet! This packed release includes metric fact table support, SCIM integration for Okta, remote evaluations for Javascript/React SDKs, data pipelining mode for Snowflake and Bigquery, AI copy suggestions in the visual editor, and more. Check out some of the improvements below, or on our blog: https://lnkd.in/g5nBSwdH Metric Fact Tables With Fact Tables, you can define one query that returns multiple values, and then define multiple metrics based on the returned values. This makes it easier to add lots of metrics that are based on very similar or the same queries. Remote Evaluation Until now, evaluations for client-side feature flags happened locally on the GrowthBook SDKs. This has large performance benefits and much better data privacy (no user PII leaves your infrastructure). With this release, we’re adding a new remote evaluation option to our JavaScript and React SDKs where feature evaluation happens on a back-end server. We’ll be adding support to mobile SDKs soon and adding more deployment options. SCIM Support for Okta SCIM, or System for Cross-domain Identity Management, is an open standard that allows for the automation of user provisioning. Any of our Enterprise customers using Okta for SSO can now add and remove users from GrowthBook directly from within the Okta UI. Support for other identity providers is coming soon. Data Pipeline Mode We added a new option for BigQuery and Snowflake to enable Data Pipeline Mode. In this mode, GrowthBook will write some intermediate tables back to your data warehouse while analyzing experiment results. This can drastically reduce the query cost, especially for teams that run a lot of experiments, each one with tens or hundreds of metrics. We’re adding support for other data warehouses soon. AI Copy Suggestions Our visual editor just got better with the inclusion of AI powered copy suggestions. Click on any text element, and then have the AI suggest alternative copy. Simulations and User Archetypes With Simulations, you can now easily see how rules will be applied to users by setting the attributes. We will also show debug information about why each rule is used or skipped. And, as many teams have specific sets of users they often target features too, you can now save sets of attributes as an ‘Archetype’ to quickly see what values they will get. Multi-organization Deployments Some larger Enterprises need an additional layer to represent their complex business structure, so we now offer self-hosted Multi-Organization deployments. Organizations in GrowthBook share a common SSO identity provider but are otherwise entirely isolated. Users in GrowthBook can belong to one or more organizations. #growthbook #opensource #experimentation #featureflags #productupdate

GrowthBook version 2.4 is now live! This release has a large number of improvements. Here are some of the highlights: Redesigned Experiment Page (V2). We continued listening to your feedback and iterating on the experiment page. This version features better support for multiple metric comparisons, clearer call-to-action buttons, and the ability to change the control variant. Feature Flags + Experiments = Better Together. You can now have multiple Features controlled by a single Experiment, more control over the Experiment lifecycle, and combo experiments that use both Feature Flags and our Visual Editor. Datadog Integration Guide. By integrating GrowthBook and Datadog, you can set up custom workflows to automatically toggle Feature Flags based on changes in your Datadog metrics. For example, roll back a release if error rates increase. You can find the guide in our docs: https://lnkd.in/gxWK8C9M. Improved Onboarding and built-in Sample Data. Setting up a new GrowthBook account from scratch is much quicker and easier. We have a new sample dataset built-in, including metrics, experiments, and feature flags (with an easy cleanup button when you’re done). Plus many more changes and bug fixes which you can read about on our blog: https://lnkd.in/g8RJSysB or on our GitHub: https://lnkd.in/gPtVGxe5

We just launched version 2.3 of GrowthBook, and want to share some of the new features: Import from LaunchDarkly. Easily transfer features, projects, and environments from LaunchDarkly directly from within GrowthBook. Automatic metric discovery with Segment, RudderStack, or Google Analytics. For users of these popular event tracking tools, we are now able to auto-detect and automatically create metrics for your tracked events. New Cloud CDN. We upgraded our CDN on GrowthBook Cloud to bring faster response times and greater reliability. This also allowed us to enable instant purges and real time streaming. Percentile capping. GrowthBook has always supported capping metric values to remove outliers and reduce variance in experiments (also known as Winsorization) and we now support doing this automatically by percentiles. Observability for self-hosted GrowthBook instances (OpenTelemetry). With this integration, you can easily monitor the health and performance of your GrowthBook instances in production. Plus many more changes and bug fixes which you can read about here on our blog: https://lnkd.in/g8yhsMTX or on GitHub: https://lnkd.in/gPtVGxe5
