Compare the best options: CharityAuctions.com, Givebutter, Handbid, and more—with real pricing, features, and what "free" actually means.

Not all "free" platforms are equal. Here is what you need to know before you choose.

Are there truly free online auction sites for nonprofits?

The short answer: it depends what you mean by free. Free online auction sites for nonprofits exist, but "free" usually means one of three things:

  1. No upfront cost. You build and test for free. You pay after you raise (performance-based) or when you go live. CharityAuctions works this way.
  2. Donor tips cover fees. The platform is free for you when donors opt to cover transaction fees at checkout. Givebutter uses this model—about 92% of donors choose to cover, so nonprofits often keep 100%.
  3. Free tier with limits. Some platforms offer a free plan with caps on items, bidders, or events. Upgrade for more.

No platform is free in every scenario. Payment processing (credit card fees) costs money. The question is: when do you pay, and who covers it? We will be honest about that in this comparison. For the full picture, see our best charity auction software guide and pricing.

What are the hidden fees in free auction software?

When comparing free online auction sites for nonprofits, ask about:

  • Payment processing. Credit card fees (typically 2.9%–3.5% + $0.30) are unavoidable. Some platforms bundle them; others separate platform and processing. Know which you are paying.
  • Platform fees when tips are off. Givebutter charges 3% when donor tips are disabled. CharityAuctions uses performance-based pricing with no optional tips.
  • Optional add-ons. Sponsorship management, livestream, extra support, or premium features may cost extra. Ask before you sign up.
  • Donor experience. When donors are asked to cover fees at checkout, that is not hidden—but it affects their experience. Some nonprofits prefer transparent pricing so bidders see one clear total.

A free online silent auction website or free online bidding platform that is truly free for you may still pass costs to donors. That is a valid model (Givebutter reports 92% of donors cover fees), but it is not the same as "we absorb all costs." Read the fine print. See CharityAuctions pricing.

What to look for in a free online auction site

When evaluating free online auction sites for nonprofits or a free online silent auction website, check for:

  • Mobile bidding. Guests bid from their phones—no app required. Increases participation by 52% and revenue by up to 30%.
  • Item catalog. Add photos, descriptions, starting bids, and fair market value. Organize by category.
  • Outbid alerts. Real-time notifications when someone outbids. Keeps donors engaged.
  • Payment processing. Integrated checkout. Card on file at registration. No manual entry.
  • Transparent pricing. Know what you pay and when. Avoid platforms that rely on optional donor tips if you prefer a clear, single total for bidders.
  • Support. Free setup help, event-day support, or both. Some platforms charge extra for support.
