Key capabilities
- Free cloud tier: Up to 100 daily active users with all security features included.
- Pro tier: From $100/month for up to 25,000 daily active users, custom domain, and 99.5% uptime SLA.
- Self-hosting: Open-source deployment for organizations that need full infrastructure control.
Core areas are passwordless and multi-factor authentication, multi-tenant organization management, and customizable identity workflows.
Shortlist Zitadel if you want a genuinely free tier for smaller user bases plus the option to self-host the same open-source code later, rather than committing to a vendor with no self-hosted exit path.
Because the free tier caps out at 100 daily active users, model expected user growth against the Pro/Enterprise pricing breakpoints before relying on the free plan for a production launch.
