GrowthBook 5.1 Release

GrowthBook 5.1 is here!

The faster you can learn what works, the faster you can make better product decisions.

GrowthBook 5.1 brings the entire learning loop together. It introduces new ways to scale experimentation, put AI to work across your workflow, and turn what you learn into knowledge your whole team can use.

Version 5.1 is available to all cloud and self-hosted users.

Read on for highlights or get the details at GrowthBook's blog.

Scale testing

Scale experimentation, both in volume and in what you can test, with Contextual Bandits and Funnel Metrics. Use our new Hosted MCP + OAuth server and an expanding AI skills library of 30+ skills to make the entire workflow fully programmable.

Nothing you learn gets lost

Capture what you learn with Learnings, a living knowledge library for your organization. Analyze more data with AI, uncover deeper insights, and share them across your organization. Our new Slack App (Beta) makes it easier to bring GrowthBook insights into the conversations where your team already works.

Product Analytics closes the loop

User Journeys and AI-powered dashboards help you understand how users move through your product, uncover friction points, and identify what to test next. Our rebuilt SQL Explorer and new agent skills lets you run richer explorations across your entire data warehouse without needing to predefine metrics, adding another tool in the agents kit for deeper, more flexible data exploration.

GrowthBook 5.1 is live on Cloud now and available for self-hosted deployments. Check out the full release notes.
