React app builder turned PR factory
Free tier + paidAI app builderstempo.new
What it is
Started as a visual prompt-to-app builder generating React and Next.js only, with a drag-and-drop editor that mutated real source rather than a mockup, plus GitHub export. It has since repositioned as an AI software factory that turns customer feedback and issues into reviewed pull requests.
Why it earns a slot
Its plan-first multi-agent flow drafts user flows and architecture before writing code, which cuts the rework that burns credits elsewhere. Flat one-credit-per-message pricing with free error fixes is unusually predictable.
Know before you commit
The product has pivoted toward team pull-request workflows and away from solo prompt-to-app building, so the vibe-coding surface may keep shrinking. React and Next.js only — no Vue, Svelte or Angular.
