We’re excited to see so many electric apps being made. The yellow apps on the left are a Clojure Spreadsheet powered by Sci, Datalevin and Electric. Made by @den1k in 2 weeks to do his dev agency’s taxes, here’s his tweet.

Please let us know if you make something, and as always eager for your feedback! Community is at #hyperfiddle.
