Self-host free, or let us run it
Seamless Auth is open source under Apache 2.0. Running it yourself costs nothing and always will. The tiers below are for teams who would rather not operate it: we provision, host, and run the same auth server on your behalf, starting with a 14-day free trial.
Free trial
The fastest way to run a real managed instance.
MVP
Managed hosting for early products and prototypes.
Business
Covers the majority of production application use cases.
Enterprise
Advanced compliance, higher scale, or custom infrastructure.
How isolation works
Every managed instance runs your auth service in its own isolated container, with its own database. On MVP that database sits on a shared, encrypted database cluster; on Business it gets a dedicated database server and an encryption key used only by your instance. Instances run on Seamless Auth's shared, hardened network (load balancer, private network, and API gateway), not in a separate cloud account per tenant. Sessions are validated in your own application against a signed token, so normal authenticated traffic never round-trips to our infrastructure. Read the architecture.
Coming from another provider
Free guides walk you off Auth0, Amazon Cognito, or any provider that exports to CSV, onto an instance you run. If you would rather have help, we run migrations as a fixed-cost service on Enterprise.
