Donate – Support ISC

Our software is open source because we believe in building a better Internet. By donating, you will be demonstrating your support for the development and growth of open source platforms. ISC is supported by a relatively small number of organizations who pay for software support: those people are sustaining the team that fixes bugs and adds features for everyone. If you use open source, please consider donating.

If everyone donated just $25 every time they downloaded software, ISC could afford to hire another QA engineer, or hire a tech writer, or do one of many other things we would love to be able to do to support the community.
