Hackathon portals are one of the most import need for any hackathon to get the projects submitted in the right way. Though one might think that these portals are just working as a form collecting data from the attendees to showcase the project, using a simple form can be a big problem in terms of Judging a hackathon!
Hackathon portal provide separate pages for judges to look over the different details of the project, providing hackers with a page where they can fill in details and publish their projects in front of the world! Other than that, various tools and services these portals provide are a great way to enhance the overall hacking and organising experience for everyone involved!
While there are a ton of different platforms to use for judging, Devpost and HackerEarth are the two most common at MLH Hackathons.
