Building a professional website used to cost thousands of pounds and require months of development. In 2025, AI website builders have fundamentally changed that equation — creating stunning, functional sites in under 60 seconds without any design skills or technical knowledge required.

With dozens of AI builders available, which one delivers the best value? This guide reviews the top options, comparing features, limitations, and real-world performance to help you choose the right platform for your business.

What to Look for in a Free AI Website Builder

  • Speed of generation — how quickly does it produce a complete, usable site?
  • Output quality — does it look professional, or generic?
  • Hosting included — or do you need to pay separately for hosting?
  • SEO features — are meta tags, sitemaps, and schema handled automatically?
  • Customisation — can you edit the result without re-generating from scratch?
  • Upgrade path — is the paid plan good value when you need more?

The Honest View on "Free" AI Website Builders

Every platform has a free tier — but the meaningful question is what you actually get for free, and what the paid plan costs. True value comes from the full package: hosting, custom domain, analytics, forms, and AI editing all bundled together at a price that makes sense for a small business.

ChilledSites charges £29/year for the Pro plan — less than most platforms charge per month — and includes everything you need to run a professional website. That is the benchmark worth measuring against.

When to Upgrade from Free

The free tier is great for testing. Upgrade when:

  • You want to connect your own domain (yourname.com, not yourname.platform.com)
  • You need to remove platform branding from your site
  • You are generating leads and need reliable form delivery
  • You want analytics to understand who is visiting your site
