Bolt.new vs v0

Option A

Bolt.new

Prompt to a running web app in the browser via WebContainers — speed-to-demo, not a SOC2 program.

Best for

• Investor and hackathon demos
• Browser-native app generation
• Founders testing whether a product should exist

Strengths

• Demo in a tab
• Honest about being early

Trade-offs

• Not production by default
• Easy to confuse preview with a company

Verdict

Bolt is a demo factory. Lovable is the other product shell. v0 is UI code. Replit is a longer classroom and cloud IDE. Cursor is where standards begin. Use Bolt to learn what users click. Then export. Confirm what persists when the tab closes. If you needed a marketing site, Framer may be less code for the same afternoon. Use Bolt to learn if the click exists. Then leave. If architecture review is next week, you are already late to Cursor. Confirm what persists when the tab dies.

Option B

v0

UI drafts that speak React and Tailwind — a component accelerator, not a company OS.

Best for

• React/Tailwind UI exploration
• Teams already near Vercel
• Component-level speed

Strengths

• The artifact is code you recognize
• Fast layout directions

Trade-offs

• Not an app company
• A11y still on you

Verdict

v0 is React UI drafts. Framer is marketing URLs. Lovable and Bolt are product shells. Cursor finishes the app. Use v0 to explore layout, then own the code. Confirm the current export path. If you needed a published campaign site, Framer is less engineering. Use v0 to explore React layout, then own a11y in the repo. Framer for marketing URLs. Lovable for a product shell. Cursor to finish. Confirm the export path. If the artifact should not be React, you opened the wrong generator.
