Benefits of Self-Hosting Logto: Complete Infrastructure Control and Data Sovereignty

Self-hosting Logto delivers full data sovereignty, customizable security policies, and complete feature parity with Logto Cloud while eliminating vendor lock-in by running entirely within your own infrastructure.

The logto-io/logto repository provides an open-source identity and access management (IAM) platform engineered specifically for operators who require absolute control over authentication infrastructure. Understanding the benefits of self-hosting Logto empowers organizations to enforce strict compliance requirements, customize security configurations, and retain exclusive ownership of sensitive identity data.

Complete Data Sovereignty

When you self-host Logto, all user identities, session data, and security keys reside exclusively in your own PostgreSQL instance. The application reads the database connection string from the DB_URL environment variable defined in packages/shared/src/node/env/GlobalValues.ts, ensuring that authentication data never transmits to external services. This architecture guarantees that sensitive information remains within your network perimeter, satisfying GDPR, HIPAA, and SOC 2 requirements for data residency.

Customizable Security Policies

Self-hosted deployments enable fine-grained control over security behaviors through environment variables. You can configure the private-key rotation grace period via PRIVATE_KEY_ROTATION_GRACE_PERIOD (specified in seconds), allowing you to define exact windows for cryptographic key updates. Additionally, features like case-sensitive usernames and multi-tenant signing-key handling are gated by configuration flags in the GlobalValues class, letting you enforce organization-specific security standards without waiting for vendor updates.

Enterprise-Grade Multi-Tenancy

Logto supports domain-based, path-based, and custom-domain multi-tenancy models for self-hosted instances. The GlobalValues class automatically detects DB-backed multi-tenancy by checking if urlSet.endpoint.hostname.includes('*'), exposing flags like isMultipleCustomDomainsEnabled that you can toggle via the MULTIPLE_CUSTOM_DOMAINS_ENABLED environment variable. This flexibility allows you to host multiple organizations or applications on a single instance while maintaining complete isolation between tenants.

Zero Vendor Lock-In

Because Logto runs as standard Node.js processes behind the Koa framework, you retain the freedom to replace any infrastructure component. Connectors are implemented as plain npm packages that you can fork, modify, or host locally, while the PostgreSQL and Redis dependencies use standard protocols. This modular architecture means you can migrate between cloud providers, upgrade database versions, or swap caching layers without proprietary constraints.

Full Feature Parity with Logto Cloud

The same codebase powers both the managed Logto Cloud service and self-hosted instances. The IS_CLOUD environment flag in packages/shared/src/node/env/GlobalValues.ts distinguishes cloud-only features, automatically disabling them when running the open-source version. This design ensures you receive immediate access to the latest OIDC, OAuth 2.1, and SAML protocol implementations without waiting for separate enterprise releases or feature backports.

Deploying Logto on Your Infrastructure

Getting started requires only Docker and a PostgreSQL instance. The repository provides a production-ready docker-compose.yml that configures both the OIDC provider (port 3001) and Admin Console (port 3002), creating a local environment that mirrors production runtime for simplified testing and debugging.

# Quick self-hosted start

curl -fsSL https://raw.githubusercontent.com/logto-io/logto/HEAD/docker-compose.yml | \
docker compose -p logto -f - up

Configure your deployment using standard environment variables:

services:
  logto:
    image: ghcr.io/logto-io/logto:latest
    environment:
      - DB_URL=postgres://postgres:mysecret@db:5432/logto
      - NODE_ENV=production
      - MULTIPLE_CUSTOM_DOMAINS_ENABLED=true
      - PRIVATE_KEY_ROTATION_GRACE_PERIOD=86400
    ports:
      - "3001:3001"
      - "3002:3002"

The middleware in packages/core/src/middleware/koa-security-headers.ts includes specific handling for self-hosted scenarios, such as allowing custom terms-of-service pages in iframes, demonstrating the codebase's awareness of private deployment contexts.

Summary

• Data sovereignty through direct PostgreSQL ownership and the DB_URL configuration in packages/shared/src/node/env/GlobalValues.ts
• Custom security policies via environment variables like PRIVATE_KEY_ROTATION_GRACE_PERIOD
• Flexible multi-tenancy with automatic detection of wildcard hostnames and custom domain support
• No vendor lock-in thanks to standard Node.js/Koa architecture and npm-based connectors
• Feature parity with Logto Cloud via the IS_CLOUD flag mechanism
• Declarative deployment using Docker Compose or Kubernetes manifests under version control

Frequently Asked Questions

Is self-hosted Logto feature-complete compared to Logto Cloud?

Yes. The identical codebase powers both environments, with cloud-only features automatically disabled via the IS_CLOUD environment variable. You receive the same OIDC, OAuth 2.1, and SAML capabilities, while the packages/api/CHANGELOG.md confirms ongoing support for both deployment models.

What database requirements exist for self-hosting?

Self-hosted Logto requires PostgreSQL as the primary datastore. The application connects via the standard DB_URL environment variable defined in packages/shared/src/node/env/GlobalValues.ts, allowing you to use managed PostgreSQL services or self-managed instances. No proprietary database extensions are required.

How do I enable custom domains in a self-hosted instance?

Set the MULTIPLE_CUSTOM_DOMAINS_ENABLED environment variable to true. The GlobalValues class detects this configuration and activates the multi-domain capabilities, enabling you to assign custom domains to different tenants within the same deployment.

Can I modify the source code when self-hosting?

Absolutely. As an open-source project under the MPL-2.0 license, Logto permits modification of the source code. You can fork connectors, adjust security headers in packages/core/src/middleware/koa-security-headers.ts, or modify the GlobalValues configuration to suit specialized requirements.
