Publicly.io is a project by the well-known makers Mubashar Iqbal and Daniel Kempe. It was built as part of a hackathon in 2017. While the site isn't overly active, it provides you an easy way to submit your project. Let's get your project submitted:

You can get started submitting your project using the button on the dashboard:

Directly after submitting the form you will have received a new backlink for your project! All in a few minutes only. If you are on the hunt for more backlinking opportunities check out Owwly, SideProjects.net, SideProjectors.com and YourStack for quick wins.
