Sebastian Bergmann's Open Source Work

Open Source is the backbone of modern software development, driving innovation, collaboration, and transparency across the technology landscape, especially on the Internet. By making source code accessible, Open Source empowers developers and organizations to adapt, improve, and secure software rapidly, while fostering a vibrant community that shares knowledge and solves complex challenges together.

I am deeply committed to Open Source: I actively contribute, advocate, and help shape its future.

As a board member with The PHP Foundation, I work to ensure the long-term sustainability of PHP. I represented Open Source interests at the European Union, championing the values of openness and collaboration.

Since 2000, I lead the development of PHPUnit, the industry-standard testing framework for PHP. Through this work, I have played a key role in professionalizing the PHP ecosystem, enabling developers worldwide to build more reliable and maintainable software.

You cannot buy PHPUnit, but you can pay for PHPUnit. You can support its ongoing development by engaging with me directly. I offer consulting, coaching, and training services that benefit you and your team.

Additionally, you are welcome to sponsor my work on PHPUnit, helping to secure its future for everyone who relies on it.
