miniapp starters is a set of open-source starter templates designed to make it easier to build Farcaster miniapps, with support for Worldcoin integrations as well. Miniapp Starters came out of our own journey building miniapps. Along the way, we found ourselves creating common patterns and components repeatedly, so we decided to turn that work into a set of reusable, community-friendly templates. Now, anyone can kickstart their own miniapp projects without reinventing the wheel.
