Dan Romero, co-founder of Farcaster, responded on social media to comments by users "hoping that the core of Warpcast is not just English users". Warpcast is a US team with no international expansion plans. The team thinks it can build a great client side for English users, but does not have enough bandwidth to serve international users. Phaver, Firefly App and supercast are client sides that do well on the international front.
