About

Free non–profit charity auction software! BiddingOwl's non–profit auction management software is free. We strongly believe in non-profit fundraising and want to make our easy-to-use software available to as many charities as possible. Our auction manager is free! We place no restrictions on the number of items, users, donors or solicitors. Why would we? We want you to succeed and raise as much money as possible. The use of our software to manage your auction is absolutely free. You can run as many silent and live auctions as often and as long as you want. However, if you like to use our online auction platform to set up your own online auction fundraiser, we do ask for 5% of your highest bids. The benefits greatly outweigh the cost. Online and pre-bid silent and live auctions raise on average far more money than the traditional format alone. Compare us to our competitors and we know you'll like us better!

About

CharityBase is a free, open source database and GraphQL API that aggregates fragmented data from the Charity Commission, Companies House, 360 Giving, charity websites, the ONS, and social media into a single, cleaned, normalized, and searchable dataset. It powers a public search portal where users can discover detailed profiles of UK charities, complete with finance, governance, and activity data, and offers a single GraphQL endpoint that responds in structured JSON with custom queries for counts, aggregates, and detailed lists. Designed to eliminate the heavy lifting of data collection and cleaning, CharityBase enables startups, grantmakers, and researchers to build digital tools, such as dashboards, reports, and grant-finding applications, without managing their own data pipeline. Its API supports both GET and POST requests, variable-driven queries, pagination, and live interactive playgrounds for rapid prototyping, all underpinned by regularly updated, audit-trail-backed records.
