Okta alternative — FAQ
Is Infinity ID a drop-in replacement for Okta?
Not a drop-in replacement. Infinity ID implements standard protocols (OpenID Connect, OAuth 2.0 with PKCE), so standards-based integrations can be migrated, but validate your SSO app catalogue, lifecycle and compliance needs before switching.
Is Infinity ID free?
Yes — Infinity ID is open source under Apache-2.0 and free to self-host. You pay only for the infrastructure you run it on.
Where is user data stored with Infinity ID?
On your own infrastructure. Because Infinity ID is self-hosted, you control where identity data lives, which can help with data-residency requirements.
