The short version
Bolt.new and Website Killer both turn prompts into deployable web projects, but the audiences barely overlap. Bolt is developer-first — an in-browser StackBlitz environment with a real terminal, package installs, and the assumption that you read code. Website Killer is non-developer-first — a chat-and-preview interface that ships a finished marketing site to a custom domain without exposing the project tree. Pick Bolt if you're a developer who wants an AI pair programmer in the browser. Pick Website Killer if you want a website, not a project.

Where Bolt.new falls short
Bolt.new is StackBlitz's in-browser AI fullstack web builder. The trade-offs we hear from teams who switch:
- Developer-leaning UX — the project-tree-and-terminal view assumes you read code
- No marketing-site templates — every project starts essentially from scratch
- No domain attach in the core flow — publishing to your own domain is manual
- Token consumption can spike unpredictably on complex prompts
- Free tier is daily-credit-based and runs out quickly on real work
- Production hosting is a separate concern, not bundled with the builder
When Bolt.new is the better choice
We're not pretending Bolt.new has no upside. These are the situations where Bolt.new is genuinely the right pick over Website Killer:
- You're a developer who wants a browser-based AI pair programmer with terminal access
- Your project needs custom npm packages, server-side logic, or anything beyond a marketing site
- You want to demo code-level work to a teammate via a shared StackBlitz URL
- You'd rather edit the codebase than the rendered site
Which one is right for you?
Founders
Website Killer. Bolt's project tree and terminal are friction for a founder who wants a credible site for the next investor meeting.

Website Killer. Our design systems give you a finished, on-brand site; Bolt's output is code-first and design-secondary.
Read more →Front-end developers
Bolt for app prototyping where code access matters. Website Killer for the marketing site itself.
Freelancers
Website Killer for client deliverables that need to be production-quality and on a custom domain. Bolt for one-off code work where the terminal is useful.
Read more →The honest story
Bolt.new is one of the best AI tools in the developer ecosystem. The StackBlitz engineering team has done genuinely impressive work to get a real Node.js runtime running in the browser, and the result is a tool that feels like a future where every developer has an AI pair programmer they can spin up in a tab. For developers, it's a great product.
The catch — and Bolt is explicit about this themselves — is that it's positioned as a 'vibe-coding tool for developers and designers.' The UI assumes you're comfortable with project trees, terminals, package.json files, npm install loops, and reading TypeScript when something breaks. That's the right design for the audience Bolt is built for.
Website Killer makes the opposite trade. Our user has never seen a terminal and doesn't want to. They want to type 'a website for a Brooklyn restaurant called Sapore — wood-fired pizza, dinner-only, reservations via Resy' and get a complete, on-brand site with a hero, menu section, hours, location, reservation CTA, and a custom domain — without ever seeing the project tree underneath. That's a different product from Bolt at a fundamental level, not at a feature level.
On pricing: Bolt's free tier is daily-credit-based and runs out quickly on real work; paid plans start around $20/month and scale up by token consumption. Website Killer's free tier is forever with 2,500 tokens per month, and Pro at $14/month bundles 25,000 tokens with 5 custom-domain slots and built-in hosting.

FAQ
Frequently asked questions
Is Website Killer like Bolt.new?
Both use AI to generate web projects from prompts, but the audiences barely overlap. Bolt is developer-first — an in-browser StackBlitz environment with a real terminal, package installs, and the assumption you read code. Website Killer is non-developer-first — a chat-and-preview interface that ships a finished marketing site to a custom domain with no project tree exposed.
Can I run terminal commands on Website Killer like I can on Bolt?
No, by design. Website Killer's interface is a chat composer and a live preview — no terminal, no project tree, no npm install. If your work requires terminal access, Bolt is the right tool. If you want a finished site without ever seeing a terminal, Website Killer is.
Is Bolt better for prototyping than Website Killer?
For developer-style app prototyping where code-level access matters, yes. For 'I need a credible marketing site live by tomorrow morning,' no — Website Killer is faster end-to-end because the deploy + domain + hosting are part of the flow, not a separate concern.
Can I host my Bolt project the way Website Killer hosts?
Bolt projects are downloaded or deployed to an external host (Netlify, Vercel, etc.) that you set up yourself. Website Killer hosts your site on our edge by default — paid plans include custom-domain slots with SSL automatically provisioned.
Is Website Killer cheaper than Bolt?
Yes for most users. Website Killer's Pro plan is $14/month for 25,000 AI tokens, 5 projects, and 5 custom-domain slots. Bolt's paid plans start around $20/month and scale with token consumption past the included credits. There's also our forever-free plan with no daily cap.
Can I use Bolt for marketing sites?
You can, but you're swimming upstream — Bolt has no marketing-grade templates, the deploy + domain flow is manual, and the UI assumes code comfort. The job-to-be-done mismatch shows up as friction. Most marketing-site work that starts on Bolt ends with the user wishing they'd picked a marketing-site tool.
Does Website Killer have a community like Bolt's?
We're earlier — Bolt has a head start on community, including a subreddit and a $100K OSS fund. Website Killer's product depth on marketing sites is genuinely deeper, but on community size and tenure, Bolt is ahead today.
Can I export Website Killer code to deploy on Vercel or Netlify?
Yes. Source-code export is available on every plan, including Free. Export the ZIP, deploy anywhere. Most users find our built-in hosting is simpler — custom domain + SSL + CDN — but the option to leave is always there.
Does Website Killer use Next.js like Bolt's templates do?
Yes — Next.js + Tailwind + shadcn primitives under the hood. The difference is what you do with that stack: Website Killer wraps it in 50+ marketing-flavored design systems and a hosted flow; Bolt gives you the raw stack and lets you build whatever.
What happens if I outgrow Website Killer's marketing focus and need real app code?
Export your Website Killer source, keep the marketing site live, and pick up Bolt or a custom Next.js codebase for the app side. The two tools coexist well — marketing on us, app prototyping on Bolt.
