Which free website builder has a custom domain for free?

The short answer is clear: no major free website builder provides a truly free custom domain. Every platform—from Wix and SITE123 to HubSpot, Canva, Webflow, and Kleap—restricts free plans to platform-branded subdomains like yoursite.wixsite.com or yoursite.site123.me. Connecting your own domain (e.g., yourbusiness.com) requires upgrading to a paid plan, a limitation consistently confirmed across independent reviews and vendor documentation. This matters because a subdomain address undermines credibility; customers often perceive it as less professional or temporary, especially when compared to a custom domain that reflects ownership and stability. For service businesses relying on trust—such as contractors, clinics, or local retailers—a branded subdomain can inadvertently signal instability, discouraging engagement before a visitor even reads your content.

Research confirms this pattern holds true across all major builders. Wix’s free plan, for example, includes a 500MB storage cap and 1GB bandwidth while displaying Wix-branded ads, with custom domain access only available on paid tiers. Similarly, Kleap’s free tier offers limited AI credits but explicitly states that custom domain publishing requires its “Launch” plan starting at $9/month, despite promotional language on its main site suggesting otherwise. HubSpot’s free CMS allows up to 30 pages but reserves custom domain connectivity for paid plans beginning at $9/month, a detail echoed by Zapier’s analysis of builder limitations. Even Canva’s free tier assigns a my.canva.site subdomain and displays a Canva footer, with domain options locked behind paid subscriptions starting at $12/month annually. These restrictions aren’t oversights—they’re intentional upsell mechanisms, as free plans universally trade functionality for platform branding and usage caps.

This reality shapes how businesses should approach website selection. While free builders lower the barrier to entry for initial setup, they impose hidden costs in perception and scalability. A custom domain isn’t just a vanity metric; it’s foundational to brand control, email professionalism (e.g., [email protected]), and long-term SEO equity. Platforms like AI Business Sites address this by including a custom domain as part of the managed setup—registered in the client’s name and owned outright—eliminating the need to navigate upgrade funnels or sacrifice credibility for cost savings. For owners evaluating options, recognizing that “free” often means “free to build, not free to brand” is the first step toward choosing a solution that aligns with both immediate needs and long-term growth.

• Wix free plan: 500MB storage, 1GB bandwidth, Wix-branded ads, no e-commerce
• Kleap free plan: 5 AI credits/day, custom domain requires $9/month Launch plan
• HubSpot free CMS: 30 pages + 1 email automation, custom domain needs paid plan from $9/month

What "Free" Actually Costs: Branding, Caps, and Locked Features

Free website builders often promise custom domains, but the research shows no platform delivers a truly free custom domain without strings attached. Free plans universally trade platform branding, strict resource limits, and disabled features for the illusion of zero cost, pushing users toward paid upgrades for basic functionality. Wix’s free tier, for example, caps storage at 500 MB and bandwidth at 1 GB while displaying mandatory Wix-branded ads and blocking e-commerce entirely, forcing users into a yoursite.wixsite.com subdomain that lacks professional credibility. Similarly, SITE123’s free plan injects a persistent floating banner across all pages and locks users into rigid, block-based layouts that severely limit design flexibility compared to the 800+ apps available on Wix’s paid ecosystem. Even HubSpot CMS’s free offering, while allowing up to 30 pages, provides a subdomain deemed "relatively unusable" for serious business due to its generic appearance and constrained automation capabilities.

The most misleading tactic involves temporary domain vouchers masquerading as permanent solutions. Hostinger’s widely advertised "free domain for 1 year" is not a forever-free benefit but a introductory perk tied exclusively to annual paid plans, which renew at $11.99/month after the initial $2.99/month introductory rate — a detail easily overlooked when comparing upfront costs. As industry analysts note, such offers represent a strategic upsell rather than genuine value, since the domain vanishes if the subscription lapses or isn’t renewed at the higher rate. Canva’s free tier similarly buries custom domain options behind paid plans starting at $12/month annually, while Kleap’s own blog admits its "custom domain publishing" feature requires the $9/month Launch plan despite being highlighted on its main site.

These restrictions directly impact businesses aiming to establish trust and scalability. Platform-imposed ads undermine brand authority, storage limits hinder media-rich content like portfolios or product galleries, and bandwidth caps risk site slowdowns during traffic spikes. Crucially, free tiers routinely exclude essentials like online selling, template switching after publish, and access to meaningful app ecosystems — features AI Business Sites includes in its $497/month managed platform alongside ownership of code, content, and domain. For service businesses relying on lead generation and professional credibility, the hidden costs of "free" builders often exceed the investment in a truly owned, unrestricted web presence. The pattern is clear: what appears free upfront extracts payment through compromised functionality, forced upgrades, or lost opportunities — making transparent, all-inclusive pricing a smarter long-term strategy for growth-focused owners.

Your free website address isn't really yours — and that distinction decides whether your business website is an asset or a rental. Before comparing builders, you need to understand what a subdomain actually is, because the "free" label hides the most important fine print in this entire decision.

A subdomain looks like yoursite.wixsite.com or yoursite.site123.me. The platform owns the root domain; you're borrowing a slice of it. You can't take it with you if you leave, you can't fully control how it appears in search results, and the platform can attach its branding to every page. On Wix's free plan, that means Wix branding displayed on all pages of your site, plus a SITE123-style "floating tag" banner is standard across free tiers.

A custom domain — yoursite.com — is the opposite. You register it, you own it, and it works anywhere. That portability is why analysts consistently frame the subdomain-versus-domain distinction as critical for credibility and flexibility.

Here's where the upsell comes in. No free builder connects a custom domain without payment. Kleap requires its Launch plan at US$9/month. HubSpot's free CMS limits you to what one reviewer called a "relatively unusable" free subdomain, with custom domains gated behind paid tiers. Even "free domain" offers are conditional — Hostinger bundles a domain voucher with annual plans, and as one analysis puts it, a voucher bundled with a subscription is not a permanently free domain.

The free tier, in other words, is the showroom. The restrictions aren't accidents:

• Platform-owned subdomains you can't transfer or sell
• Mandatory ads and branding on every page
• Storage and bandwidth caps — Wix free allows just 500MB storage and 1GB bandwidth, per TechRadar's testing
• No e-commerce and limited features until you upgrade

This is why ownership is the real issue, not price. A subdomain puts your entire online presence at the platform's mercy: change their terms, pricing, or policies, and your address, traffic, and search equity go with them.

Zoom out and the principle applies beyond the domain. A business website you don't fully own — the domain, the code, the content, the lead data — is a liability dressed as a freebie. This is the standard we hold ourselves to at AI Business Sites: your domain is registered in your name, and you own everything on the site. Whatever builder you choose, ask one question first: if I leave, what do I actually take with me?

The "free" plan rarely stays free once you need a real domain. Across the major builders, connecting a custom domain almost always requires upgrading to a paid plan — a pattern that holds whether you're looking at Wix, SITE123, HubSpot, or Canva, according to industry analysis of free builders.

Before you commit, run the numbers on the full picture. Wix's free plan caps storage at 500MB with 1GB of bandwidth, runs on a yoursite.wixsite.com subdomain, and displays Wix-branded ads on every page of your site. The cheapest paid plan (Lite at $17/mo annual) unlocks the custom domain — plus 2GB of storage. HubSpot's free plan allows up to 30 pages, but custom domain ability requires paid plans starting at $9/month, and its free subdomain has been described as "relatively unusable" by reviewers at Zapier.

Watch for three common traps:

• Introductory pricing that renews higher. Hostinger's "free domain for 1 year" comes only with annual plans that start at $2.99/mo and renew to $11.99/mo — and there's no forever-free plan, just a 7-day trial.
• Per-account eligibility. Canva's free tier shows a my.canva.site subdomain, and domain options require checking per account — they're simply not available on the free tier.
• Trial cliffs. WebWave offers only a 14-day trial; an eligible paid plan is required after the trial just to keep your site live and connect a domain.

As one builder review puts it plainly: "A domain voucher bundled with a subscription is not a permanently free domain." When you add up the upgrade path — the paid plan, the renewal rate, the storage you'll eventually need — the true monthly cost of "free" often lands between $9 and $17 before your first year is out.

There's a simpler way to think about this: what you actually want isn't a free builder, it's a domain registered in your name, a site you own outright, and a predictable monthly cost. That's the model behind done-for-you builds like AI Business Sites, where the domain is registered in the client's name, the code and content and data belong to the owner, and terms are month-to-month with 30 days' notice — no lock-in, no feature gates. You're paying for a finished, managed website rather than assembling one from a free tier and upgrading piece by piece.

If a real custom domain is the goal, evaluate total cost of ownership first — then decide whether building it yourself is worth the hours, or whether having it done for you makes more sense.

So which free plan actually wins? The honest answer from the research: none of them give you a custom domain for free — the real question is whether a free plan fits your goals at all.

If you're building a hobby site, a portfolio, or a temporary project, free plans genuinely work. One reviewer at WebsitePlanet put it plainly: there's no reason you couldn't use Wix's free plan forever, so long as you don't mind the branding and aren't selling anything. That's the trade in a nutshell — free is fine when credibility, sales, and lead capture don't matter.

The moment any of those things matter, free plans break down fast. The restrictions stack up quickly:

• Wix's free tier caps you at 500MB storage and 1GB bandwidth, with Wix-branded ads on every page and no e-commerce, per hands-on testing.
• SITE123 displays a visible "floating tag" banner on all free sites, and free users are stuck on a yoursite.site123.me subdomain.
• HubSpot's free CMS subdomain was called "relatively unusable" by Zapier's testing team.
• Even "free domain" offers like Hostinger's are only free for one year with an annual paid plan — as one analysis notes, a domain voucher bundled with a subscription is not a permanently free domain.

For a business, these aren't small annoyances — they're lost customers. A visitor who sees yoursite.wixsite.com and a builder's ad banner questions whether you're a real business. And a free plan that can't take orders, capture leads, or follow up automatically is a brochure, not a sales system.

That's the decision framework in one line: free plans work for projects; businesses need ownership — a domain in your name, hosting you control, and a site built to convert. The upsell path is real, too. Custom domains start around $9/month on Kleap and HubSpot, and $12/month on Canva, and that's before you've added e-commerce or removed branding.

If you've read this far and recognized your business in the "outgrown free" column, it may be worth a conversation about what fully owning your web presence would actually look like — a custom site, your own domain, and lead capture working from day one, rather than a template you'll eventually have to migrate off.

Book a free, no-obligation strategy call with AI Business Sites to talk through your website, your goals, and whether a done-for-you build makes sense. It's a real conversation, not a sales pitch — and you'll leave with a clear picture either way.
