At GrowthBook, our mission is to provide the insights you need to build better products that grow your business faster. With GrowthBook 4.2, we’ve added a beta version of GrowthBook Product Analytics. Now our users will have a single integrated platform for feature management, experimentation, and product analytics.
In addition, we’ve continued to enhance the developer experience, making experimentation at scale and integration into any stack easier than ever. Finally, for companies seeking an alternative to Statsig, our Statsig to GrowthBook Migration Kit automates importing feature gates and dynamic configs while replacing Statsig SDKs with GrowthBook SDKs.
Release 4.2 is available immediately to both our cloud and self-hosted users. Visit our Pricing page for details about Starter, Pro, and Enterprise options.

GrowthBook Product Analytics (Beta)
Adding Product Analytics to the GrowthBook platform closes the loop for development. Now, you can go from feature management to experimentation to product analytics in a single tool. While in beta, Product Analytics will be available to all users.
Turn your warehouse data and metrics into actionable product insights. Explore user behavior, share dashboards, and make smarter decisions about what to build next. With Product Analytics, you will be able to:
- Build and share dashboards that combine graphs, pivot tables, and text
- Create custom charts and tables from any data in your warehouse
- Use GrowthBook SQL Explorer with our AI-powered text-to-SQL capabilities to query, aggregate, and group data
- Access any metric defined in GrowthBook and track its performance over time
This Product Analytics beta provides a glimpse of what’s to come as GrowthBook develops more self-service tools for building, analyzing, and exploring all of your product data. Let us know what you think in our Slack community!
Statsig to GrowthBook Migration Kit
With the OpenAI acquisition of Statsig, we saw a spike in interest in GrowthBook. Product teams looking for alternatives expressed concern about what would happen to their data. Others worried that the product might be discontinued or deprioritized. To make the transition from the acquired platform to an open-source alternative as effortless as possible, we created the Statsig to GrowthBook Migration Kit, free for all users.
- Statsig Importer instantly copies over feature gates, dynamic configs, and segments.
- Statsig Code Migration Tool (powered by Claude Code) automatically replaces Statsig SDKs with GrowthBook SDKs.
Enterprise Enhancements
The 4.2 features below continue our investment in the developer experience that makes GrowthBook a top choice for product development teams with high volume apps and advanced experimentation programs.
Metric Slices: Simplify Experiment Design
When users create experiments, they often want to look at a number of metrics across common dimensions like product categories or device types. This can lead to the need to manage a number of metrics. Metric slices solves this problem. Enable auto slices on a Fact Metric once, and GrowthBook automatically generates drill-down analyses for each dimension value across all experiments using that metric.
Instead of creating separate “Orders” metrics for each product category or device type, you can enable Auto Slices on those columns with a single metric which means fewer redundant metrics, faster setup, and cleaner reporting.
Incremental Refresh
We revamped our Data Pipeline Mode to lower query costs and improve performance for long-running experiments and high-traffic apps. By storing intermediate results and incrementally refreshing them, we’ve seen users save up to 85% in query costs. This first version is available on BigQuery, Presto, and Trino. We’ll be adding support for more data warehouses based on customer demand.
Official Metrics
Many organizations rely on a trusted set of “official” metrics. GrowthBook now makes these easier to manage by letting admins mark and edit official metrics directly from the UI (previously API-only). This helps standardize measurement, reduce confusion, and promote consistency across teams.
New SQL Template Variables
You can now access custom field values and phase data directly in your metric and experiment SQL, unlocking several use cases:
- Fine-tuned query optimization using non-date partition keys
- Reuse of SQL definitions with minor tweaks per experiment
- More accurate joins between experiment exposure and phase data
Custom Validation Hooks
GrowthBook has always been flexible — and now it’s even more so. Self-hosted enterprise users can write custom JavaScript validation hooks that run in secure V8 isolates. Use them to:
- Require tags on feature flags
- Prevent targeting rules containing PII
- Enforce naming conventions or internal policies
These hooks let teams automate governance without slowing down development.
Edge Remote Eval
Edge Remote Eval lets client-side SDKs offload feature flag evaluation to a backend server, preventing targeting logic from leaking to users. Previously, this required managing your own GrowthBook proxy servers. Now, you can deploy a Cloudflare Workers–based Remote Eval server — a fast, low-cost, zero-maintenance alternative built on Cloudflare’s global infrastructure.
Quality-of-Life Improvements
Big thanks to all of our users who reported bugs, shared feedback, and contributed ideas to this release on GitHub or Slack.
Many small improvements add up to a big boost in usability:
- Faster and more relevant search algorithm for features, metrics, and experiments
- Create feature rules in multiple environments at once
- Better column-type detection for BigQuery Fact Tables
- Add metric row filters based on Boolean columns
- Reduced webhook noise (no more notifications for unpublished drafts)
- Slack and Discord notifications now include more detailed change info
- Custom pre-launch checklist items can be scoped to specific projects
- Faster database schema browsing, even with hundreds of tables
- New setting to disable legacy metrics for smoother transition to Fact Tables
- Sortable experiment results tables — quickly see top or bottom performers
Plus dozens of smaller fixes and performance improvements.
2025: A Year of Rapid Innovation
The 4.2 release is GrowthBook’s sixth major update in 2025, capping off what has easily been the biggest year of innovation in our company’s history. GrowthBook launched over 45 new features across four major themes in 2025:
- Experimentation at Scale: New metrics, templates, dashboards, and analytics
- Feature Management: Safe rollouts and feature analytics
- Artificial Intelligence: A new MCP server and embedded AI capabilities
- Developer Experience: Managed data warehouse, native Vercel integration, 13 updated SDKs, enhanced server-side rendering, and support for new CMSs and FerretDB
Whether you’re on the Starter plan ready for more advanced experimentation and analytics or a Pro user building a culture of experimentation, we’re ready to help you grow. We’re excited to see what you build — and how you use these new tools to learn faster.
