Your church needs a website — but most website builders weren't designed with your needs in mind. Sermon pages, event signups, prayer requests, online giving, volunteer registration — these aren't features you should have to hack together with plugins. Nucleus is a premium, all-in-one church website builder purpose-built so that any staff member or volunteer can create and manage a modern, mobile-first church site without writing a single line of code.^1
At the heart of Nucleus is a philosophy of "invitation over presentation." Rather than building a digital brochure, Nucleus helps churches create an interactive hub where people can take their next step — whether that's planning a visit, signing up for a small group, submitting a prayer request, or giving online. The platform's signature feature, the Launcher, is a branded floating button that lives on every page, putting every important action one tap away.^2 Flows replace traditional forms with conversational, one-question-at-a-time interactions that consistently drive higher completion rates.^3 Add in a dedicated sermon manager with built-in podcast hosting, a private Prayer Wall, scheduled Banners for time-sensitive announcements, and native Planning Center integration, and you have a church communication platform that covers nearly every need.^1
Created by Brady Shearer — founder of Pro Church Tools and a recognized voice in church communications who has been featured on Christianity Today — Nucleus is bootstrapped and proudly independent: no investors, no data mining, and no skimming a percentage off donations.^4 The platform's approach to giving is a standout: instead of taking a cut of every gift (standard practice in church tech), Nucleus charges a flat subscription fee so churches keep virtually every dollar donated.^6
