Logto

What it is for

Logto is an open-source CIAM desk: you host a sign-in box, attach SSO or organizations, and you can start Cloud Free at $0 (50k MAU) or self-host. Use it when the job is login you start at $0, not when you need a $20 chat seat.

What makes it unique: the cover is the official Logto sign-up experience (ACME create-account, Google / Discord) from the GitHub product still — not a pricing card. The box itself is ops of Sign-in.

Key features

• Sign-in experience — the hosted sign-up / sign-in box you brand (Build your sign-up form; pricing). One session. Passkeys, TOTP, and social buttons are options on this. The cover is ops. Account APIs are install.
• Organizations — multi-tenant orgs for a SaaS (Introducing Organizations; pricing Organizations add-on $48). A tenant, not a login. Free does not include the org bundle.
• RBAC — roles and API resources (pricing RBAC / API resources). A grant, not an org. Pro includes 3 API resources, then $4 each. Permission-per-resource is this surface.
• Enterprise SSO — SAML / OIDC connectors (pricing Enterprise SSO $48 / connector). A federation, not a local password. Third-party OAuth apps are $8; SAML apps are $96.
• Self-host — the open-source app you run; Cloud is Free / Pro / Enterprise (pricing self-hosted plans). A deploy, not a login. Cloud Free is $0 / 50k MAU / 50k tokens.

Tokens and MAU are the Cloud meters. Pro’s floor is $24 / month plus add-ons. Machine-to-machine extras are $8 each after the first. Custom domains are $48 for up to 10 after the first.

Who it's for

Best fit: SaaS teams who will stay on Free $0 (50k MAU, 50k tokens, no card) while they ship a first sign-in box, then buy Pro at $24/month when they need unlimited MAU and start attaching org / SSO add-ons.

Confirm checkout; taxes follow your location.

Limitations / costs

• Pro’s $24 is a floor. Orgs + SSO + MFA already add $48 each.
• A CIAM box, not a full IAM for employees. For orgs, actions, and 100-DAU Free see ZITADEL. For secrets see Infisical.

Alternatives

• ZITADEL — an identity desk with organizations and actions when you want IAM, not only a sign-in box.
• Infisical — secrets and PAM when you are not hosting login.
• Unkey — API keys when the “user” is a key, not a person.
