Built in the open
Site9 is fully open source under the Apache 2.0 license. Browse the code, report issues, suggest features, or contribute directly. Every business deserves great software — and great software is built together.
Why open source?
Community-driven
Anyone can contribute templates, features, and improvements. The best ideas come from the people using the product.
Transparent and secure
Every line of code is auditable. No hidden tracking, no vendor lock-in. You can self-host if you want full control.
Free for everyone
Small businesses shouldn't need expensive tools to get online. Open source keeps the barrier as low as possible.
