The POCO C++ Libraries project was started by Günter Obiltschnig (@obiltschnig) in 2004. Back then C++ was rapidly reaching its absolute low point in popularity, as almost everyone was following the trend to managed and virtual-machine based programming languages. Nevertheless, Günter believed in C++. He wanted to create a comprehensive set of libraries that cover all modern-day programming needs. For himself, but also for other C++ programmers struggling to find high-quality and easy-to-use C++ libraries for network programming, XML (and later JSON) processing, database access, and all the other features virtually every modern application needs.
The first release of the C++ POrtable COmponents (as it was called back then, and from where the name POCO came from) was in February 2005. Shortly after the first release, Günter was joined by Aleksandar Fabijanic, who has been a contributor and co-project lead ever since.
More than 180 developers have contributed code to the POCO C++ Libraries since the beginning.
POCO has been used in hundreds, if not thousands, of projects worldwide. Whether building automation systems, industrial automation, IoT platforms, air traffic management systems, enterprise IT application and infrastructure management, security and network analytics, automotive infotainment and telematics, financial or healthcare, C++ developers have been using the POCO C++ Libraries in challenging and mission-critical applications.

The POCO C++ Libraries project is jointly governed by a Technical Steering Committee (TSC) which currently consists of:
- Günter Obiltschnig
- Aleksandar Fabijanic
The TSC has final authority over this project including:
- Technical direction
- Project governance and process (including this policy)
- Contribution policy
- GitHub repository hosting
- Conduct guidelines
- Maintaining the list of additional Collaborators
The TSC can be contacted at firstname.lastname@example.org.
The POCO C++ Libraries GitHub repository is maintained by the TSC and additional Collaborators who are added by the TSC on an ongoing basis. Individuals making significant and valuable contributions are made Collaborators and given commit-access to the project. These individuals are identified by the TSC and their addition as Collaborators is discussed during TSC meetings.
Modifications of the contents of the GitHub repository are made on a collaborative basis. Anybody with a GitHub account may propose a modification via pull request and it will be considered by the project Collaborators or TSC. All pull requests must be reviewed and accepted by a Collaborator with sufficient expertise who is able to take full responsibility for the change.
Security issues or vulnerabilities can be reported via email directly to the core team at email@example.com. The core team will respond to security issues within 24 hours. If you need to send sensitive information, get in touch first.
Code of Conduct
The POCO C++ Libraries project and its community adhere to the Contributor Covenant Code of Conduct.
Funding & Sponsorships
The ongoing development and maintenance of the POCO C++ Libraries requires a lot of resources. That is why sponsors are needed to help funding the project. Donations to the project are currently managed by Applied Informatics Software Engineering GmbH. As part of a sponsorship agreement, Applied Informatics will provide commercial-grade support to project sponsors. The details are stated in the POCO C++ Libraries Sponsorship And Support Agreement (PDF). Alternatively, we also welcome companies funding the development of a specific feature for POCO.
Three sponsorship levels are offered: GOLD, SILVER and BRONZE. All sponsorship levels include a sponsor acknowledgement on the website, as well as a certain level of technical support. The minimum sponsorship fees for the three levels are EUR 32.000 for a GOLD sponsorship, EUR 9600 for a SILVER sponsorship and EUR 3200 for a BRONZE sponsorship. Sponsorship fees are for a 12 month period and have to be paid upfront.
Need a specific non-trivial feature in the POCO C++ Libraries, but don't have the resources to develop it yourself? You can pay the POCO maintainers to implement a feature in POCO. We also have a list of features looking for a sponsor. Please contact the project maintainers for more information.
