Documentation
Start with the browser SDK, verify a flag outside production, then roll it out or run an experiment. Each guide stays focused on the steps you need in the console and your app.
Quickstart
Install the browser SDK in any app and send your first event.
Environments
Use separate keys for development, staging, and production deployments.
SPAs & cross-domain
Load the SDK before your app router, and link visitor identity across domains.
Feature flags
Create a flag in the console and evaluate it in your app with the SDK.
Experiments
Run a two-variant A/B test, record exposures, and measure conversions.
Server SDK
Evaluate flags and experiments from your backend with a secret key.
Signing tokens
Sign viewer context tokens with your environment secretKey.
