Building a free Polymarket screener: how I turned 13,963 markets into a single scannable page
A developer created a free screener for Polymarket, consolidating 13,963 markets into a single page for easier scanning. The tool pulls data from the public Gamma API and updates every few hours, allowing users to identify market movers and volume leaders. The project is open-source and hosted on GitHub, with no associated costs for users.

- ▪The project is open-source and available on GitHub, allowing for community contributions and feedback.
