👋 FOSSBilling (FOSS: Free and Open Source Software) is a billing and client management solution. We help digital businesses with an easy-to-use and free solution. What differentiates us from most of our competitors is being fully open-sourced. You can audit what's running on your server. Or better, contribute to the project.

How FOSSBilling works

If you're a programmer, FOSSBilling is many different libraries, languages and technologies. The core is in PHP. We store data in a MySQL database. For the client area, we use Bootstrap, Font Awesome, jQuery and other libraries to make it look and work great. The admin area uses Tabler, a free and open-source admin area template. We also recommend Docker to run FOSSBilling. The source of FOSSBilling is available in fossbilling/fossbilling on GitHub.

This website uses 🦖 Docusaurus, a free and open-source documentation site generator from Meta. Docusaurus is a great and easy-to-use tool for building documentation websites. Docusaurus is built on top of React. The pages are written in MDX. The source of this website is available in fossbilling/docs on GitHub.

If you have experience in any of these technologies, we need new faces to help us out. Be brave, create your first pull request! We also have a small team of contributors who are always looking for new people to help out. Even if you don't know how to code, you can still give back to the community by providing feedback or just saying hi.
