Become a sponsor to John Blackbourn

My name is John Blackbourn. I'm one of the core committers to the WordPress open source project and I maintain many popular plugins and tools for WordPress developers, including:

I develop and support these in my spare time and have done so for over 10 years. I'd love to continue working on them. As an alternative to launching paid "pro" versions of my plugins I'd like sponsorship to become a workable support model so they can remain free and accessible to everyone.

  • If you work at an agency that develops with WordPress, ask your company to provide sponsorship in order to invest in its supply chain. The tools that I maintain probably save your company time and money, and GitHub sponsorship can now be done at the organisation level.
  • If you make a living developing with WordPress and any of my tools help you do your job, your support via sponsorship is greatly appreciated.

You can contact me directly with any questions.

Thank you!
