Overview

Logto is a modern open-source customer identity (CIAM) platform built by Silverhand, founded in 2021 and headquartered in Singapore. It targets startups and mid-market teams building consumer and B2B applications who want a developer-friendly identity provider with prebuilt sign-in flows. Logto is open core: the server is open source and self-hostable, with Logto Cloud as a managed option for teams that prefer not to operate it. For background on the category, see what is CIAM.

What it is good at

Developer experience and polish are the strengths. Logto ships a clean prebuilt sign-in experience, OIDC and OAuth 2.0 support, social and enterprise connectors, multi-tenancy through organizations, RBAC, and passwordless options including passkeys. The admin console and SDKs are well documented, so a small team can get production auth running quickly. Being open source and self-hostable means full data control and no per-user license cost when you run it yourself.

Where it falls short

As a younger project, Logto's enterprise depth, governance, and audit tooling trail incumbents, and its ecosystem of integrations and third-party expertise is still growing. Federation breadth and advanced lifecycle provisioning are lighter than a full enterprise IdP such as Keycloak or Zitadel. Self-hosting means you own scaling, upgrades, and availability.

Pricing

The Logto core is free and open source, self-hostable at no license cost. Logto Cloud is a managed, usage-based tier. Model self-host versus managed with the TCO calculator.

Best for, and who should look elsewhere

A good fit for startups and product teams that want a modern, developer-friendly open-source CIAM with the option of a managed cloud. Look elsewhere if you need deep enterprise governance, a large mature ecosystem, or extensive enterprise references. Teams wanting a similar OSS-plus-cloud model should also compare Zitadel.

Bottom line

A modern, well-designed open-source CIAM that is a strong choice for startups and mid-market teams, with a managed cloud for those who would rather not self-host.
