+title: "Sponsoring Jekyll's development"

+
+_(TL;DR: We're open for sponsorships on our [OpenCollective page](https://opencollective.com/jekyll))_
+
+Hi Jekyllers,
+
+As you may know, Jekyll is a completely free and open source project. We offer our
+software and its related plugins and documentation at no cost because we believe
+that good software should not cost anything. We're not planning on changing that,
+but today I want to talk about a different monetary aspect of open source.
+
+Open source developers being paid for the work they do is a rare sight. Most open source
+software is effectively the result of hundreds and thousands of hours of free labor provided
+by individuals who are passionate enough to work outside of their day job to create
+software that, ironically, is being used by almost every company that offers
+digital services. It's a problem that has gotten more attention in recent years, with
+the open source community becoming more diverse and more and more companies actively
+investing in providing monetary support for open source developers.
+
+Jekyll has always been a product of volunteers. Rarely has someone been paid to implement
+a certain plugin or feature. Today, we're excited to announce that we will finally
+be able to fund our contributors! __We are opening an OpenCollective to receive
+individual and corporate sponsorships__. This is not unheard of, [Hugo](http://gohugo.io)
+is also funded by sponsorships, as are many other similar projects, such as
+[webpack](https://opencollective.com/webpack), [Babel](https://opencollective.com/babel) or
+[RuboCop](https://opencollective.com/rubocop).
+
+OpenCollective is a service that makes it easy for open source projects to receive funding
+from individuals and companies alike. It's specifically designed for open source and
+many other projects already use it for funding.
+
+Sponsoring is, for us, a method to finally realize some of the more ambitious goals we've had
+with the project for years. The closest thing we want to realize is to __release Jekyll 4.0, and
+to make it as polished as we can__. In the future, we would also like to work on other things that
+will improve the Jekyll ecosystem. Here's a couple of ideas:
+
+- Create a comprehensive official plugin and theme directory site
+- Improve tooling built around measuring and improving Jekyll's performance
+- Improve maintenance for official plugins
+- Including the community into official decisions; making Jekyll more friendly to folks in the community
+
+Again, these are just some ideas, but with the help of sponsoring, they are now one step closer
+to being realized :heart:
+
+<div align="center">
+  <img src="/img/forestry-logo.png" width="300" />
+</div>
+
+With that, we would like to announce our very first sponsor: [__Forestry.io__](https://forestry.io)! Forestry is
+a CMS that integrates with your Jekyll sites and lets you update content using a beautiful
+interface, and then automatically commits it back to your GitHub repository. We're excited to have
+them on board on a new, exciting step of our journey.
+
+Will anything change for Jekyll users? The answer is no - this step does not impact the Jekyll software
+in any aspect. In fact, you might see positive changes, such as more features and better
+performance. Surprisingly, that's what happens when you properly fund people for their work!
+
+If you have been a long time user for Jekyll and would like to give something back to the project,
+you can consider a small monthly donation to our [OpenCollective page](http://opencollective.com/jekyll).
+If your company heavily relies on Jekyll, do consider sponsoring us! Contact me at
+`olivia at fastmail dot com` and we'll figure something out together.
+
+Thanks for sticking with us, and happy Jekylling! :tada:
