Is there any free website builder with truly no hidden costs?

GitHub Pages comes closest, since hosting is free indefinitely and you only pay for an optional custom domain, which is a cost you'd have on any platform.

Hidden Costs of Free Website Builders Nobody Talks About

Direct answer: The five most common hidden costs of free website builders are: paid custom domains, ad-removal upgrade fees, storage and bandwidth overage charges, e-commerce checkout gating, and the labor cost of a full rebuild if you switch platforms later.

1. Custom Domains Aren't Actually Free

Nearly every free builder markets itself as free while quietly requiring a paid plan (or a separately purchased domain from a registrar) for a professional yourname.com address instead of a builder-branded subdomain.

2. Ad Removal Is a Paywall

Several free builders inject their own ad banner into your published site. Removing it is one of the most common reasons users upgrade within the first 90 days.

3. Storage and Bandwidth Caps

Free plans typically cap storage around a few hundred megabytes to 1GB and bandwidth similarly. A site with a lot of images or video, or one that goes viral, can exceed these limits quickly.

4. E-Commerce Is Rarely Free

Most free plans let you display products but block the actual checkout and payment processing step, which is gated behind a paid plan.

5. The Switching-Cost Trap

The largest hidden cost is often time: rebuilding a site from scratch on a new platform after outgrowing a free one, because the original builder didn't allow a clean export.
