The hardest part of vibe coding isn’t the coding. It’s deciding what to build. Most people sit on a vague idea for years and never start. The cure for that is a smaller idea you can finish this weekend.
Here are 10 we’ve seen students actually build, in roughly increasing order of difficulty.
1. A church or ministry website
The simplest, highest-leverage project for almost any Christian. Service times, address, sermons, contact form, give button. One afternoon.
Stack: Next.js + Tailwind, deployed to Vercel. Free.
Time: 2–4 hours.
2. A daily devotional reader
Pulls in a public-domain devotional (Spurgeon’s Morning & Evening, My Utmost for His Highest, etc.) and shows the day’s entry. Simple, fast, useful.
Stack: Next.js + a JSON file.
Time: 2 hours.
3. A family chore or routine app
Built for your own family. Each kid has a list of daily routines. They check them off. You see the progress. Multiplied bonus points if your kids help build it.
Stack: Next.js + Supabase for storage.
Time: 3 hours.
4. A Bible reading plan tracker
Pick a reading plan (Robert Murray M’Cheyne’s, the Bible Project’s, etc.), display today’s readings, let users mark them complete. Streaks optional.
Stack: Next.js + localStorage (no backend needed).
Time: 3 hours.
5. A small group prayer wall
Members of your small group can post prayer requests and see each other’s. Simple email login, prayer count, mark as answered.
Stack: Next.js + Supabase + email auth.
Time: 4 hours.
6. A homeschool curriculum tracker
Track which lessons each kid has completed across subjects. Add a calendar view. Add the ability to print weekly reports.
Stack: Next.js + Supabase.
Time: 5 hours.
7. A “sermon notes” web app
People in your church can take notes during the sermon, save them, and look them up later. Add scripture autocomplete for bonus points.
Stack: Next.js + Supabase + Stripe (if you want to charge).
Time: 6 hours.
8. A scripture memorization tool
You enter verses you want to memorize, the app quizzes you with progressively harder gaps. Spaced repetition algorithm under the hood. Great way to learn.
Stack: Next.js + a tiny algorithm + localStorage.
Time: 5–6 hours.
9. A Christian e-commerce store
Sell anything — books, art prints, T-shirts, devotional cards. Connect Stripe, ship from your garage. The whole MVP can fit on a single page.
Stack: Next.js + Stripe Checkout. Skip the database for v1.
Time: 4–6 hours.
10. A SaaS for your specific industry
This is the big one. You know an industry better than 99% of developers. Build a small tool that solves one problem in that industry. Real estate agents, insurance brokers, financial advisors, contractors, dental offices — pick the world you already understand.
Stack: Next.js + Supabase + Stripe + AI features as needed.
Time: 1–2 weekends for v1.
How to actually pick one
Don’t pick the biggest one. Pick the smallest one you can finish this weekend. Finishing is the magic. Once you’ve finished one tiny thing, the next thing feels possible.
The students who do best in our 3-Hour Challenge are not the ones with the most ambitious ideas. They’re the ones who picked something small enough to actually ship. Six months later, those same students are running real businesses. Meanwhile the people with the “big idea” are still planning.
Pick small. Ship fast. Build the next one.
