Best free silent auction software: an honest 2026 roundup
Several platforms offer a free way to run a silent auction — but 'free' works differently on each. Here's how the main options actually compare.
✓ Free for up to 20 items · Unlimited bidders · No credit card required
Search “best free silent auction software” and you'll get a wall of lists that conveniently rank whoever published them first. This one is built differently: it explains how each platform's free tier actually works, so you can pick on substance rather than whoever shouted loudest. The single most important thing to understand up front is that “free” is funded differently on each platform — usually through optional donor tips, a percentage of funds raised, or paid upgrades.
The picks
32auctions
Free for up to 20 items with unlimited bidders and no credit card. Bidders bid in the browser — no app. No platform commission and no contract; optional per-event upgrades add branding and more items. Best when you want a genuinely free start and to keep 100% of what you raise.
Givebutter
Offers a free-to-start model funded largely by optional donor tips, bundling auctions with broader donation and campaign tools. A good fit if you want auctions alongside general fundraising in one place and are comfortable with the tip-based model.
GalaBid
Provides a free plan for online auctions supported by optional donor tips, focused on quick mobile bidding. Worth a look for straightforward auctions where you want minimal setup.
BetterWorld
Markets a free auction tool aimed at smaller nonprofits, with the platform funded by optional supporter contributions. Reasonable for basic online auctions.
RallyUp
Has a free plan for online activities with an optional-tip model, and supports combining auctions with raffles, crowdfunding and other formats within one campaign.
How to choose between free options
Match the model to your event and your comfort level:
- Want to keep 100% and avoid donor tips? Choose a platform with paid upgrades instead of a commission or default tip — that's the 32auctions model.
- Running general fundraising alongside the auction? An all-in-one like Givebutter may consolidate tools, if you accept the tip-based funding.
- Just need fast mobile bidding? A lightweight option like GalaBid or BetterWorld can be enough.

Best free silent auction software FAQs
What is the best free silent auction software?
It depends on your event. 32auctions is a strong pick for online and hybrid silent auctions that want a genuinely free start with no commission and no app for bidders. Other platforms fund their 'free' tiers through optional donor tips or a platform percentage — fine for some organizers, but worth understanding before you choose.
How do free silent auction platforms make money?
Usually one of three ways: an optional 'tip' added to each donor's payment, a percentage of funds raised, or paid upgrades. 32auctions uses optional per-event upgrades and doesn't take a commission or add a forced donor tip.
Is free silent auction software good enough for a real fundraiser?
Yes, for most online and hybrid silent auctions. A free tier that includes unlimited bidders, mobile browser bidding and outbid notifications covers what the large majority of school, church, team and nonprofit auctions actually need.
