What is the best open source Farcaster client? 
Are there any right now?
I saw Opencast on GitHub but it doesn't display anything on the page besides Server error.

I did one you can check out here: https://github.com/PinataCloud/farcaster-photo-client-template did a blog post breaking down the main pieces too! https://www.pinata.cloud/blog/how-to-build-a-farcaster-client
