Is WikiTree Really Free to Use, and How Is It Funded?

Updated

Yes. According to WikiTree's own site, "Everything on WikiTree is free for everyone, forever." There is no subscription or payment required to use the site. The project covers its expenses through unobtrusive advertising, and members who sign the Honor Code see fewer of those ads while gaining member benefits that would cost money on other genealogy websites.

What "Free Forever" Means on WikiTree

WikiTree describes itself as a collaborative global family tree built for "our cousins and descendants to enjoy for free, forever." The free access is presented as a core part of the project's identity rather than a temporary promotion or a limited free tier.

The site's stated scale gives a sense of what that free access covers:

Metric Figure cited on WikiTree
Years growing 17
Community members 1,420,721
Ancestors and cousins on the tree 46,511,696
Profiles with DNA connections 16,861,115

These numbers describe the tree itself, not a paid product — the profiles, search, and collaboration tools are part of the same free environment.

How WikiTree Is Funded

WikiTree states that its expenses are covered by unobtrusive advertisements. That is the funding mechanism named on the site. There is no mention of a required subscription, paywall, or mandatory donation to use the core service.

Two practical consequences follow from that model:

  • Ads support the site. Because advertising pays the bills, you may see ads while browsing.
  • Signing the Honor Code reduces ads. WikiTree says members who sign the Honor Code "don't even see most of the ads," and also "enjoy member benefits that cost money on other websites."

What the Honor Code Changes

The Honor Code is a member commitment, not a purchase. Signing it is described as the step that unlocks fewer ads and additional member benefits. If you want the cleaner, ad-light experience, signing the Honor Code is the relevant action — not paying a fee.

What to Keep in Mind

  • Free does not mean unmoderated. WikiTree emphasizes accuracy and collaboration, with features like Connection Checkers that ask members to verify relationships using reliable genealogical sources.
  • The community is active. The site highlights a G2G forum, a weekly question, and volunteer-driven projects, which is where much of the day-to-day help happens.
  • Member experiences reflect long-term value. In member interviews on the site, Skye Sonczalla (member since 2016) says the information collected over 25 years of research feels "safeguarded," and Roger Peterman (member since 2025) says he values his WikiTree efforts more highly than any prior accomplishment. These are member statements, not guarantees about your own results.

Bottom Line

If your question is whether you must pay to use WikiTree, the answer from the site is no: it is free for everyone, forever, funded by unobtrusive ads, with fewer ads for members who sign the Honor Code. The main "cost" is participation — contributing to and helping maintain a shared tree.
