Migrate from Statsig

This guide walks through migrating feature flags, experiments, and SDKs from Statsig to GrowthBook.

Import Your Statsig Data

Use GrowthBook's import tool to migrate your Statsig configuration and experiments.

warning

The Statsig import tool is currently in a private beta. Please contact support@growthbook.io if you're interested in using it.

Step 1: Generate Statsig API Key

• In Statsig, go to Settings → ** Key & Environments**
• Create a new "Console" key with read-only permissions
• Copy the key (it starts with secret-)

Step 2: Run the Import

• In GrowthBook, go to Settings → Import your data
• Select Statsig
• Enter your Statsig API key
• Click Fetch from Statsig

The import tool will retrieve:

• Environments (production, staging, etc.)
• Tags
• Segments
• Feature Gates
• Dynamic Configs
• Experiments

Step 3: Review and Confirm

Items will show as:

• Pending: Will be imported
• Skipped: Already exists in GrowthBook

You can:

• Uncheck items to remove them from the import
• Click the arrow (>) to view item details
• Click Import to GrowthBook when ready

When Status is marked as complete, your data is available in GrowthBook 🎉

Installation

Download the subagent to your Claude Code agents directory:

# Create the agents directory if it doesn't exist
mkdir -p ~/.claude/agents/

# Download the agent file
curl -o ~/.claude/agents/statsig-to-growthbook-sdk-migrator.md \
  https://raw.githubusercontent.com/growthbook/claude-statsig-to-growthbook-sdk-migrator/main/.claude/agents/statsig-to-growthbook-sdk-migrator.md

Using the Subagent

In Claude Code, simply ask:

"I need to migrate this code from the Statsig SDK to the GrowthBook SDK: (@filename or directory)"

The subagent will:

• Convert import statements to GrowthBook SDK
• Transform feature gates to boolean flags
• Migrate dynamic configs to feature values
• Flatten StatsigUser objects to GrowthBook attributes
• Generate a migration report with any manual steps needed

🔗 See the GitHub repo for more details.
