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:
- 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.
- 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%.
- 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 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.
