Every niche has something people want to discover -- local coffee shops, SaaS tools for marketers, remote-friendly employers, indie games. A directory site captures that intent and monetizes it with paid or featured listings. Founders who understand this have been launching "Yelp for X" micro-SaaS products for years. The business model works. What kills the idea is the setup time.
If you spend the first two weeks wiring up auth, payments, and email just to reach the point where you can build the actual directory, you will lose the momentum to ship. This is exactly the problem a Next.js SaaS boilerplate solves -- not by doing the directory-specific work for you, but by eliminating the infrastructure you would rebuild anyway.
Strip away the niche and most directories share the same set of requirements:
Every item on that list is infrastructure. None of it is the directory idea itself.
The boilerplate ships with JWT-based auth -- register, login, password reset, and email verification -- wired up and ready. You do not configure it; you use it. Submitters create an account, and their user ID is attached to every listing they submit. If you want to lock submission behind login, that is one guard in the service layer:
const user = await getUserFromRequest(req); // throws 401 if not logged in
If you later want Google or GitHub login so submitters can sign in without a password, the OAuth social login pattern is a drop-in addition.
The simplest monetization for a directory is a one-time "featured listing" fee. A submitter pays once and their listing appears at the top of search results or gets a "Featured" badge.
Stripe Checkout handles the payment. You create a session, redirect the submitter, and listen for the checkout.session.completed webhook to mark the listing as featured in your database. The boilerplate already has the Stripe one-time payment pattern -- webhook endpoint, signature verification, and Drizzle ORM order tracking -- so you are adding the "mark listing as featured" step, not building payment infrastructure from scratch.
If you want recurring featured placement -- say, $9/month for a sponsored slot -- the subscription billing pattern is equally pre-built.
Two emails matter for a directory:
Both are transactional emails. The boilerplate uses Resend and react-email for exactly this. You write the email as a React component, pass it to emailService.sendEmail(), and Resend delivers it. No SMTP config, no template engine to learn. The transactional email setup walks through the full pattern.
Once you have a hundred listings, visitors want to filter by keyword. PostgreSQL full-text search handles this well at directory scale -- you get relevance ranking, partial matching, and no additional service to pay for.
The boilerplate uses Neon DB (serverless Postgres) and Drizzle ORM. Adding a tsvector column to your listings table and querying it takes less than an afternoon, and the full-text search guide has the exact migration and query pattern.
Every directory listing looks better with a logo or cover image. The boilerplate integrates Cloudinary for uploads -- a protected API route accepts the file, uploads it to Cloudinary, and returns a URL. You store the public_id in your database, not the raw image. Cloudinary handles resizing, format conversion, and CDN delivery automatically.
With infrastructure out of the way, your real work is:
listing module: schema, validation, repo, and service following the DDD-lite module patternThat is a focused scope you can ship in a weekend. You are not ignoring the hard parts -- you are starting with them already done.
A Next.js boilerplate is not a no-code tool. You or someone you hire will write code. The tradeoff is: instead of spending the first two weeks on auth, payments, and email that every SaaS needs, you spend those two weeks on the directory product itself. The infrastructure is already correct, tested, and production-ready.
If you have never shipped a full-stack product before, this boilerplate gives you a working mental model of how the pieces connect -- modules, services, repositories, API routes -- before you start adding your own features.
Pick your niche, clone the Next.js SaaS boilerplate, and start building the listing module. Auth is done. Payments are done. Email is done. The directory is yours to build.
