Upbiddr is a website for discovering projects, creators, and brands through public rankings. Its Ranking Cards represent an external website, project, or public presence and display information such as a description, target link, and current ranking value. Users can browse cards and leaderboards to find listed projects. Users can create a free public profile to bring together links and introduce themselves, a brand, or a project. They can also publish a free Ranking Card, then share either the profile or the card, which has its own share image. Ranking positions can be changed through paid bids or points earned on the platform. The site also provides ranking statistics and sign in by email code and link. A typical workflow is to create a profile, publish a card with a link to an external page, and share it with an audience. Visitors can explore the card and follow its target link. Upbiddr is accessed through a web browser; the supplied site information does not specify separate device or software requirements.
