## 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](https://startwithidentity.com/guides/fundamentals/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](https://startwithidentity.com/vendors/open-source/keycloak/) or [Zitadel](https://startwithidentity.com/vendors/open-source/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](https://startwithidentity.com/tools/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](https://startwithidentity.com/vendors/open-source/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.
