FidesHunt is an open, community-ranked directory that helps people discover Catholic software and services. Its listings cover tools used for prayer, study, formation, parish life, media, and more, with rankings shaped by votes from the people who use them. Visitors can browse by category, cost, platform, language, and features such as open-source availability, or sort listings by rating, recent activity, or date added.

The directory brings together a wide range of products, including Bible and daily reading apps, breviaries and Liturgy of the Hours tools, Rosary apps, Catholic formation programmes, apologetics resources, and prayer services. It also features media and virtual experiences, community platforms, AI and search tools, and software for developers, including APIs and open infrastructure. Listings include both free and paid options, and link to their respective publishers.

FidesHunt offers a searchable directory alongside a JSON API and RSS feed for keeping up with new listings. Users can submit products, vote, and report corrections.
