Rename from Frames v2

In early 2025, Frames were renamed to Mini Apps to better reflect their evolving capabilities and scope. The new Mini Apps standard builds upon the foundation established by Frames, offering enhanced functionality and a more intuitive developer experience. Key points about the transition:
  • All existing Frames documentation and resources have been migrated to the Mini Apps ecosystem
  • Frames v1 have been deprecated and will be supported only until the end of March 2025
  • Developers are strongly encouraged to migrate existing Frame projects to the Mini Apps standard
  • The Mini Apps standard maintains backward compatibility while introducing new features
If you’re familiar with the previous Frames implementation, you’ll find that Mini Apps preserve the core concepts while expanding the possibilities for creating rich, interactive experiences within the Farcaster ecosystem.
