v0 is Vercel's AI website generator that outputs production Next.js + shadcn/ui code. People want alternatives that are free, open-source, run locally, or output to different frameworks (Vue, SvelteKit, plain HTML).
Bolt.new from Stackblitz is the closest open-spirited v0 alternative. Free tier generous, paid plans cheaper than v0.
github.com/stackblitz/bolt.newBolt.new from Stackblitz is the closest open-spirited v0 alternative. Free tier generous, paid plans cheaper than v0. Live preview in browser, ships full Next.js or Vite apps. Open-source CLI (bolt.diy) also available for full self-host.
You want a generous free tier and faster live preview iteration than v0.
You're deeply in the Vercel + shadcn ecosystem — v0 outputs are cleaner there.
Open-source self-hosted version of Bolt. Run locally with BYO API key (Claude, GPT, DeepSeek, Ollama). No subscription. The most flexible alternative if you want full control over the model + generation pipeline.
You want a fully self-hosted AI website builder with BYO model. Or you want to fine-tune on your own design system.
You don't want to set up local infra — Bolt.new hosted is easier.
Not a direct v0 replacement, but Open Interpreter can scaffold and ship websites via CLI. Best for developers who prefer terminal + free-form prompting over a hosted UI.
You're comfortable in the terminal and want maximum flexibility — generate sites, scripts, anything.
You want WYSIWYG website previews — v0 or Bolt are better.
