Start free. Pay when your users show up.

A user who signed in to your production environment in the last 30 days. Test environments are never counted.

An app your users sign in to, in production: a web app, a single-page app, a mobile or desktop app, or a CLI. APIs and backend services are free: a single-page app and the API it calls count as one. Test environments have no limit.

A project is one set of users and sign-in pages, with a test and a production environment, holding your apps. Free and Startup include one project, Team 3, Scale 10, and Enterprise as many as you need.

In production: 2 sign-in apps, 5,000 monthly active users and every sign-in method (email codes, magic links, passwords and social logins), with the "Powered by Anchr.ing" badge. In test: every feature, passkeys and two-step verification included, with no limits, so you can build everything first.

Your users keep signing in. On a paid plan, each started 1,000 past your plan's number costs €3 a month on Startup, €2 on Team and €1.50 on Scale, on your next invoice. We email you at 80% and 100%, and the dashboard shows what is coming. On Free, upgrade when it suits you. Sign-in apps, SSO connections and members are counted when you add them: past your plan's number, you upgrade first.

Startup and up: passkeys, authenticator apps with recovery codes, and requiring two-step verification for every user. On Free they work in test; if you move down to Free, users who already set one up keep using it and can remove it, but nobody adds a new one in production.

Any time, in Billing in the dashboard. Upgrades are prorated; a cancellation takes effect at the end of the period you paid for.

Yes. Paying for a year costs ten months: two months free. You can switch between monthly and yearly in the dashboard.

When you sell to businesses: their employees sign in through their own identity provider (SAML or OIDC), and SCIM keeps their accounts in sync. Team includes one connection, Scale three, and each extra is €75 a month. Enterprise covers as many as you need, with custom limits and terms.

Anchr.ing on a dedicated EU deployment, or on your own servers under licence, with Simon ApS as your EU contracting party and no US processors in the chain. It comes with a DPA, support terms, and escrow or a perpetual licence of the installed version. Write to us for a quote.

Every customer gets its own namespace with separate test and production databases, on every plan. Our server reaches each one only through that environment's own database user, so even a bug in our code can't read another customer's data: the database refuses the query.

Feature flags and support chat come with every plan. Billing your own users will be sold separately, later; it is not on a plan and not sold yet. Interested? Write to hello@anchr.ing.
