Free link in bio that allows a custom domain

OwnBio is one option: its basic link-in-bio page is free, and you can connect a domain you already own after inviting 5 verified members through its Priority Program. (ownbio.app)

If you mean free with no referral requirement, I didn’t find a clearly established service that offers that on its free plan. For example, Bio Link says custom domains require Pro, and SOCIA TAP includes them on its paid plan. (help.bio.link)

You’ll still need to own or pay for the domain itself.

Most free link-in-bio tools don't include a custom domain on their free plans. A few options come closer:

• Campsite: Sources conflict. One review says Campsite has built a reputation specifically around a free plan that includes custom domain support. Another comparison lists its custom domain as Pro and up, so check the current pricing page before relying on it.
• Lnk.bio: Its paid tiers include a free domain. For a limited time, Lnk.Bio premium users can claim a .bio custom domain free for the first year. You'd need a UNIQUE or ULTRA plan, and after the first year, the domain renews at $75 per year.
• Hostus: Its comparison table lists a custom domain, but the free plan is limited to 20 documents and 2 MB, so it's not a standard link-in-bio page.

Most others, including Linktree, Beacons, and Alllinks, put custom domains behind a paid plan. For Alllinks, the usual cost is typically £4 to £10 a month.

If you want a truly free setup with your own domain, you can also skip link-in-bio tools. Build a simple one-page link list with a free host such as Cloudflare Pages or GitHub Pages, then point a domain you already own at it. The only cost is the domain registration itself, typically around $10–15 a year.

It is important to clarify that virtually all professional "link-in-bio" services reserve custom domain support for their paid tiers. Providing a custom domain requires the service to handle SSL certificates and domain mapping for your unique URL, which carries ongoing costs for the platform.

While you will struggle to find a service that offers custom domain support on a permanently "free forever" plan, there are cost-effective ways to achieve this.

The Reality of "Free" Custom Domains

• No truly "Free" Tier: If a platform claims to be free, it almost always uses its own branded domain (e.g., linktr.ee/yourname or bio.link/yourname).
• The "Workaround" (Self-Hosting): If you want a 100% free solution with a custom domain, the only way to do this is to build a simple landing page yourself (using a tool like CommonNinja or a basic HTML builder) and host the code on your own server or a free static hosting service (like GitHub Pages or Netlify). This requires technical effort but removes the "upgrade wall" entirely.

Best Low-Cost Options

If you are willing to pay a small amount to remove branding and use your own domain, these are the most highly regarded options for affordability:

Summary Recommendations

• If you have $19/year: Carrd is widely considered the best value. It is technically a one-page website builder, but it functions perfectly as a link-in-bio tool and is significantly cheaper than the monthly subscriptions of mainstream services like Linktree.
• If you want a one-time payment: Lnk.Bio is often cited for having flexible pricing that avoids high monthly recurring costs compared to competitors.
• If you want to stay strictly free: Stick with a platform like Bio.link or Beacons. You will have to use their branded domain (e.g., bio.link/yourname), but these platforms are highly functional and have the most generous free features, allowing you to build a professional-looking page without needing a custom domain immediately.

A note on "Free" offers: Be wary of new or obscure tools advertising "Free custom domains." They often use this to gather data or may monetize your page through intrusive ads, which can negatively impact your brand's professionalism.

If you mean free to use your own domain, Kleap says you can publish a bio page free, but connecting a custom domain is a paid extra. ⁴

For a free bio page plus a custom domain, Beacons lists a free custom domain on its $10/month plan—not its free plan. ¹² Gravatar offers a domain free for the first year, then charges renewal. ²

So, based on these options, I’m not seeing a clearly verified service that lets you connect an already-owned custom domain to a link-in-bio page at no cost. If you’re okay paying for the domain itself, Gravatar’s first-year offer may be worth a look.
