Prompt-to-app builders matured fast in 2026. All four of these ship a working web app from a sentence, but they optimize for different builders.
Bolt.new – fastest zero to running
Bolt.new runs the entire stack in your browser with WebContainers: npm installs, databases and hosting included. The free tier grants 1M tokens per month, and Pro is $25 per month for 10M tokens with rollover. Nothing beats it for hackathons and MVPs.
v0 – the developer’s choice
Vercel’s v0 generates clean React and Next.js with Tailwind and shadcn/ui, then deploys in one click. Free gives $5 in credits and 7 messages a day; Plus is $30 per user per month with $30 of monthly credits. If your team already lives on Vercel, v0 is the obvious pick.
Replit – prototype to production
Replit’s Agent builds apps from chat and hosts them on the same platform, with Postgres, auth and scheduling built in. Starter is free; Core costs $20 per month ($18 yearly) with monthly model credits and unlimited publishing; Pro is $100. It is the only one of the four you may never outgrow.
Lovable – friendliest for non-developers
Lovable stays the smoothest for founders who never want to see a file tree: prompt, connect Supabase, ship. The free tier is usable and Pro is $25 per month.
Our take
- Speed to first demo: Bolt.new.
- React teams on Vercel: v0.
- Real production apps: Replit.
- Zero-code founders: Lovable.
Start free on all four – each tier is honest enough to evaluate before you pay.
