First Login and UI Tour

After starting GrowthBook with Docker, the first thing to do is create the admin account and set up your organization.

1. Open http://localhost:3000 (or your Cloud URL) in your browser.
2. Click Get Started or Register — you will be prompted to create the first admin account. Enter your name, email, and password.
3. Create your Organization — give it a name (e.g., “My Company”). This is the top-level container for everything in GrowthBook.
4. (Optional) Create a Project — Projects let you group features and experiments within an organization. Click Create Project and give it a name.
5. Review the default Environments: GrowthBook creates development, staging, and production by default. You can add or rename them under Settings → Environments.
6. Explore the left sidebar:
   • Features — your feature flags.
   • Experiments — A/B tests.
   • Metrics — define what success looks like.
   • Settings — SDK connections, environments, team members, data sources.

🧪 Key point

The first account you create becomes the organization admin. There is no separate admin-creation step — whoever registers first owns the organization.

Trade-offs

Option	Benefit	Cost
Single admin account	Fastest to get started	Single point of failure — no one can recover if the admin leaves or forgets the password
Multi-user org with role-based access	Safer, scales with the team	Takes longer to set up initially

Common mistakes

• Using a personal email as the sole admin instead of setting up team invites from the start
• Skipping 2FA/security settings during initial setup
• Not naming the organization clearly from the start, causing confusion once there are multiple projects

💡 Real-world example

Engineering teams commonly set up SSO and role-based access from day one of setup, to prevent unauthorized configuration changes.
