Open-source LMS for building and selling courses with a block-based editor, built-in payments, AI tools, analytics, and white-labeling. Self-host or use the cloud.

LearnHouse is an open-source learning management system built for educators, creators, and organizations who want to launch and sell courses without being locked into a proprietary platform. It covers the full workflow: create content, organize it into courses, accept payments, track learner progress, and brand the whole experience as your own.

The centerpiece is a block-based editor that handles text, video, code, quizzes, file uploads, and embeds on a single page. No juggling separate tools to mix content types. Courses are structured into modules, and you can publish and monetize them quickly through built-in Stripe integration.

Key capabilities include:

  • White-labeling: custom colors, domain, and branding throughout
  • AI tools: built into the platform for content and learner engagement
  • Analytics: track learner progress and course performance
  • Communities and boards: social and collaborative learning spaces alongside courses
  • Podcasts and playgrounds: content formats beyond standard video-and-text courses
  • 19 languages: full i18n support out of the box
  • Integrations: YouTube, Vimeo, Loom, Figma, Typeform, Slack, Zoom, Mailchimp, Google Drive, and more

For teams with more complex needs, the enterprise tier adds multi-tenancy, SCORM importing, SSO/OIDC, RBAC, audit logs, and SLA support. These are the features that separate it from lighter course creation platforms that don't scale to organizational use.

Compared to closed alternatives like Teachable or Kajabi, LearnHouse is AGPLv3-licensed and fully self-hostable. Your data stays where you put it. The REST API and CLI give developers room to build custom frontends, automate workflows, or integrate with existing infrastructure. It's also GDPR-ready, which matters for teams serving EU learners.

  • Curation system for organizing and sharing valuable resources
  • Wiki functionality for building collective knowledge bases

Technical excellence meets simplicity - containerized deployment gets you running in minutes, while robust architecture supports SQLite or PostgreSQL backends with S3 integration. Features auto-tagging, auto-organization, and comprehensive API access.

Built for the long term with state-of-the-art security, headless options for custom frontends, and extensible design that grows with your community. Transform fleeting interactions into lasting knowledge gardens.
