All-in-one free fundraising and CRM for nonprofits
Strengths
- +Genuinely free with no paid tier: no platform fee, no processing fee, no contact limit and nothing gated behind an upgrade
- +Zeffy absorbs the card processing costs, so the organization receives the full amount a donor gives, whether or not that donor adds a contribution

Weaknesses

- -No auctioneer-led live bidding, paddle raise or fund-a-need, and no live streaming for a hybrid gala, so a large seated event run from a stage is better served elsewhere
- -No SMS or text-to-give marketing, and no volunteer management
