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.
GrowthBook Statsig importer

​
Step 1: Generate a Statsig Console API Key

  • In Statsig, go to Settings → Keys & Environments
  • Create a new “Console” key with read-only permissions
  • Copy the key (it starts with console-; server secret- and client client- keys will not work)

​
Step 2: Run the Import

  • In GrowthBook, go to Settings → Import your data
  • Select Statsig
  • Enter your Statsig Console API key
  • Choose the GrowthBook project to import into, and select a Data Source if you want to import Metrics
  • Click Fetch from Statsig
The import tool will retrieve:
  • Environments (production, staging, etc.)
  • Tags
  • Segments
  • Feature Gates
  • Dynamic Configs
  • Experiments
  • Metric Sources (beta)
  • Metrics (beta)
A few things do not come over automatically yet:
  • Metrics and Metric Sources require a connected Data Source at import time, and only warehouse-native Statsig metrics are supported
  • Imported experiments do not include their metrics or exposure query — assign those in GrowthBook after importing

​
Step 3: Review and Confirm

Items will show as:
  • create: New item that will be added to GrowthBook
  • update: Item already exists in GrowthBook and will be updated
  • skip: Item is unchecked and will be left untouched
You can:
  • Uncheck items to remove them from the import
  • Filter items by tag, or show only new or updated items
  • Click the arrow (>) to view an item’s Statsig definition and, for existing items, a diff against what’s in GrowthBook
  • Click Import to GrowthBook when ready
When the import status is marked as completed, your data is available in GrowthBook 🎉

Migrate Your SDKs

Automated SDK Migration Use our AI-powered migration assistant to automatically refactor your code from Statsig to GrowthBook SDKs. Supported SDKs
  • JavaScript
  • Typescript
  • React (client-side)

​
Installation

Download the subagent to your Claude Code agents directory:

​
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.

​
Terminology Mapping

A Statsig Dynamic Config maps to a GrowthBook feature flag with a JSON value. To get the typed, schema-validated side of a Dynamic Config, back the flag with a Config (Enterprise) — a reusable object that carries a value and a schema, which is enforced on any flag it backs. The import tool creates plain JSON features; attaching a config is a manual step afterward. For simple reusable values shared across flags, see Constants.

​
Next Steps

  1. Test your imported features in a development environment
  2. Assign metrics and an exposure query to your imported experiments
  3. Configure webhooks and integrations
  4. Review team permissions and access controls
