greenbytes was founded in June 2000 as consulting and software development company with a heavy bias on technologies driving the Net.

Open Source

In 2015 we developed the implementation of the HTTP/2 protocol for the famous Apache HTTP Server, which is used in about half of the web sites on our planet. Initially sponsored by the GSMA, the implementation has been donated to the Apache Software Foundation and become part of the core product.

As a member of the Apache httpd project committee (PMC) we continue to work on improvements and features, especially in the exciting area of HTTP/2 and web performance.


During the last years we have been very active in various working groups in the "Applications and Real-Time" of the Internet Engineering Task Force (IETF): (→WebDAV )

Finally, Greenbytes provides an XSLT-based formatter for the IETF RFC XML dialect: see RFC 7749 for the specification, and Transforming RFC7749-formatted XML through XSLT for the implementation.

Document Management

Our work in the Document Management space has also led us into other standardization efforts, such as the W3C HTML5 Working Group, the JSR-283 (Java Content Repository) Expert Group, and the OASIS Content Management Interoperability Services (CMIS) Technical Committee. If you're looking for experts in these areas, do not look further!

This expertise has been applied successfully into our customers' products and we took experience from those projects back into the standardization work. It is our belief that this way of working will generate the best standards and interoperable, excellent applications. (→customers )
