Logto

Open-source OIDC identity service

Free tier + paidAuth & user managementlogto.io

What it is

Open-source identity service built on OIDC, available self-hosted or cloud-hosted. Provides a customizable sign-in experience, RBAC, organizations, MFA and machine-to-machine tokens. The free tier covers 50,000 MAU; the $24/mo Pro plan removes the MAU cap and bills on tokens plus per-feature add-ons.

Why it earns a slot

A proper standards-based OIDC provider you can run yourself, useful when you need to issue tokens to your own APIs and services rather than only log humans into a web app.

Know before you commit

Pro looks cheap until add-ons stack up: enterprise SSO is $48 per connector, SAML apps $96 each, and the organizations, MFA and advanced security bundles are $48 each — a modest B2B setup passes $200/mo quickly.
