It's the preferred AI builder for developers who want AI-accelerated productivity without sacrificing code ownership or framework flexibility. Bolt-generated apps follow standard web development patterns and deploy instantly via one-click integrations with Netlify. Pricing starts with a free tier and scales to Pro from $20/month for heavier usage.
