What it is
Bolt.new builds and runs full-stack apps entirely in the browser, on StackBlitz's WebContainers. It was shipped with no marketing — a single tweet — and did $60K ARR on its first day.
The company behind it was weeks from shutting down the year before. StackBlitz had three million developers using it and under $1M in ARR; Bolt took it to roughly $40M within five months.
