Reviewers mostly praise bolt.new for speed and convenience: they say it can turn prompts into working apps, landing pages, and demos in the browser with little or no setup, and several non-coders found it easy to use. More technical users highlight full-stack scaffolding, package installs, deployment, and editable codebases as real strengths. But the main complaints repeat too: token use feels opaque and expensive on bigger projects, larger codebases need more guidance, edits can break unrelated parts, and several paying users report serious support and billing problems.
