Logto: sovereignty score and 8 European alternatives

Logto is an authentication platform for developers who build SaaS and AI applications. It provides multi-tenancy, enterprise single sign-on and role-based access control, so application teams do not have to build the identity layer themselves. The source code is published on GitHub under the MPL-2.0 licence. Logto can be self-hosted, and the vendor also offers Logto Cloud as a managed service.

The company behind Logto is Silverhand Inc., a Delaware corporation with a contracting address in Wilmington, United States. The company describes itself as remote-first. With Logto Cloud, customers choose a region for their tenant; the vendor lists the EU, Australia, the United States and Japan. As a US company, Silverhand is subject to US law, including the CLOUD Act. A self-hosted installation keeps data on infrastructure the organisation chooses, while an EU tenant does not change the vendor's jurisdiction. The Data Processing Addendum is part of the terms of service.

Why digital sovereignty matters with Logto

Logto is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Logto hosts data in EU, US, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Logto is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Logto together with your other vendors and gives a total score, a heatmap and the main risk drivers.
