## Open Source SaaS Business

Running a business on an open source product combines community-driven growth with commercial monetization. The open core model offers a self-hosted free tier and a managed cloud tier with additional features and support.

**1,000** GitHub Stars

Open Source Phase

Design the core product as fully open source under a permissive or source available license. Make self-hosting straightforward with a single-command Docker setup.

Community Phase

Invest in documentation, issue response time, and contributor experience. Community health drives organic discovery more than any paid channel.

Monetize Phase

Offer a managed cloud tier with convenience and compliance features. Add enterprise support contracts and SSO as gated paid features.

> The open source project is a marketing channel as much as a product. Treat the developer experience of your self-hosted version as seriously as your cloud product. Bad self-hosting documentation kills community trust.
