brag about it: X · LinkedIn

a0.dev and Firebase Studio land in almost the same spot when AI assistants talk about app builders: both score just 3 out of 100 overall, with Claude giving each an 8 while ChatGPT and Perplexity give both a 0. a0.dev shows up in 4 of 69 answers, Firebase Studio in 3 of 69. Head-to-head, they tie in 17 questions, a0.dev edges ahead in 2 (like mobile app building and non-technical founders), and Firebase Studio leads in 1. Neither is mentioned for prototyping over a weekend or working with Supabase. Essentially a coin-flip pairing, with a0.dev holding the slimmest of edges.
