PRICING
Simple, sovereign pricing.
Sovereign by default, and EU GDPR AI Act ready — on every plan, not as an upgrade.
Start with identity, or build a whole app — identity is included either way. Every plan
is billed per workspace, per month, and keeps your users' data in the EU by default. AI
is metered as you use it, or bring your own key.

Per workspace / month
Identity
Login as a service.
Give your users one secure, EU-sovereign login — hosted for you, on your brand and your
domain. It works the way “Sign in with Google” or “Sign in with Microsoft” works: once
somebody has an Atom9 account they sign in with one click, anywhere you allow it. Same
standard, same convenience — kept in the EU.
- Free for the first week, then €3.99 a month
- OpenID Connect login authority — sovereign, EU-hosted
- Four assurance levels — which lock for which door
- Email & password, passkeys, email links
- One sign-in app
- Hosted on Atom9 domain (id.atom9.com)
- Standards-based: works with any OIDC library
- Working examples for ten stacks in the docs
For: a first product that needs real sign-in
today — solo builders, prototypes, internal tools.

- Included identity (Sovereign)
- One project — site, content & pages

Who it’s for
Built for two kinds of people.
You run a company, not a dev team
You need a website or a small system that is actually compliant — GDPR, cookies, AI
disclosure — in the age of AI, without learning what any of those acronyms expand to.
You describe it; Atom9 builds it and the checks have to pass before it goes live.
You build software and need EU sign-in
Your product needs login and your lawyers need it sovereign. Atom9 is a standard
OpenID Connect authority hosted in the EU — one config block in the stack you already
run, working examples for ten of them.
Comparison
How Atom9 compares.
Honest version: the categories below are good products. The difference is where your
data lives, who does the compliance work, and what you have to know.
Category descriptions are general and current as of mid-2026;
check each vendor for specifics. Third-party names belong to their owners and are used
only to identify the category.
AI usage
AI is metered — or bring your own.
Metered AI actions
Pay only for the AI work you use, measured in AI actions. No AI usage, no AI bill — it's separate from your plan, so your base cost stays predictable.
Bring your own key
Prefer your own AI provider? Connect your own key and Atom9 uses it directly — no markup, no per-action fee. You keep the model relationship and the invoice.
What every plan includes.
- Data hosted in the EU, sovereign by default — no US login providers unless you knowingly add them.
- Encryption at rest, per-workspace isolation, and a tamper-evident audit trail.
- Built-in GDPR tooling: access, export, and erasure for your users.
- Billed per workspace, per month. Cancel anytime — see Refunds.
Prices exclude VAT where applicable. Selling to your own customers? Atom9 stays a software platform — you own the payment relationship and take your own cut. See Terms 8.
