Heroku is joining the CNCF at the platinum level, upgrading the long-held CNCF Salesforce membership. This marks my third time serving on the CNCF board for different companies, and I’m excited to participate again. Joining the CNCF at the Platinum level signifies a major commitment, reflecting Heroku’s dedication to the evolving landscape.

Today, we are announcing that you can now easily share your buildpacks with the world, by registering them with the Heroku Buildpack Registry.

As of this post, the Buildpack Registry contains over 100 buildpacks created by authors like you. Because of your contributions, Heroku developers can easily use languages and frameworks like Meteor, Elixir, and React in their applications.
