Nucleus is engineered to save your church money

Nucleus reclaims money being spent on outdated and ineffective communication channels in your church. Instead of paying for (and working to maintain) multiple platforms — just point everyone to your Nucleus!


Every day, people in your community are searching for a church. But instead of checking out your service, they’re first checking out your website. Sadly, 96.2% of church websites fail the first impression test. But it doesn’t have to be this way.Nucleus is a new kind of church website builder. From single-click templates to advanced integrations, Nucleus is unlike anything else out there. Why just have a website, when you could have a Nucleus?

Mobile App

Half of U.S. smartphone users download zero new apps per month. Moreover, even if you can convince someone to download your app, there's just a 2 in 10 chance that person becomes an active user.Nucleus can do anything a church app can do (and more!) Nucleus is also built mobile-first and feels just like an app on your phone. Why pay for both?


Bulletins involve printing costs plus physical assembly & distribution every single week. The bigger problem? Most bulletins still end up in the trash.Nucleus can serve as your digital bulletin and so much more. No recurring printing costs. No physical assembly. Accessible anywhere & anytime. Nucleus is beautiful and interactive on every device. Plus, it doesn't require complicated design software to change and update.

Paper Signups

Tracking next steps manually through emails, phone calls, and paper signups simply doesn't scale. These methods require extensive volunteer or staff work and function on a one-to-one basis. Moreover, remembering long phone numbers and email addresses make things very difficult for your congregation.Nucleus captures next steps in an infinitely scalable way. Sign ups, registrations, and connection cards are stored automatically in your personal Nucleus database. Forget tracking and documenting everything one by one. With Nucleus, next steps are tracked automatically & infinitely.


Managing your church's operations through the lobby and welcome desk on Sundays works great - but only on Sundays. During the other six days of the week, this method is completely ineffective.Nucleus is accessible 24/7 from any web browser on any device. Your church can sign up for events, register for ministries, send in prayer requests, give, check the calendar, revisit the message notes, plus anything else you want to add. Nucleus looks stunning on desktop, tablet, and mobile and is available 7 days a week.
Here’s what real churches are saying about how Nucleus helps them save
A conservative estimate is 10 hours a week that we saved by moving from a church app and WordPress site to Nucleus. AND Nucleus outperforms everything else!Jason Bedell, Lead Pastor
Nucleus has more than paid for itself. The simplification of communication and signups in our church has been phenomenal over the past year.Devin Mitchem, Student Pastor


What kind of technical skills do I need to use Nucleus?
None! The Nucleus editor is extremely intuitive and easy to use. Everything is drag and drop and straightforward. Getting set up takes just a couple of minutes. Adding and editing cards is as simple as a couple of clicks. You don’t need any special web skills or coding experience.
Does my church need to sign a contract?
Nope! Nucleus offers billing on a month-to-month basis. There are no contracts whatsoever, so your church isn’t locked into anything long term. You can cancel at any time. Of course, if you want to maximize your savings, we also offer annual plans that come with a 20% discount.
Does Nucleus have a free trial?
We sure do! Nucleus offers a 30 day free trial - and you don’t even need a credit card to get started. Just click here to start your free trial.
What really makes Nucleus so special?
Every church hopes to accomplish the same thing: help people love God, love others, and make disciples. Of course, the only way to accomplish this mission is for our congregations to take next steps. Sitting on the sidelines and being spectators just won't cut it. Nucleus is the world’s first and only central hub platform for churches. It's designed to increase the number of next steps happening every week in your church. More next steps leads to more life change - and that's the foundation for a healthy church.
