Every technical founder faces this decision. You have a SaaS idea. You know how to code. Should you buy a starter kit or build everything yourself?
The answer is almost always: buy the starter kit. But the reasoning matters, because understanding why will help you make better decisions for your specific situation.
The Hidden Cost of Building From Scratch
When founders say "I'll build it from scratch," they are usually thinking about the interesting parts: the core feature, the unique value proposition, the thing that makes their product different.
They are not thinking about:
Email verification flows. Password reset tokens with expiration. Role-based access control. Stripe webhook idempotency. Dynamic sitemaps. Admin panel for content management. Transactional email templates. Legal pages. Cookie consent. i18n setup. Docker configuration. Database migration strategy. Deployment pipeline.
None of these are interesting. All of them are necessary. All of them take time.
A realistic estimate for a senior developer building a production-grade SaaS foundation from scratch, doing it right: 200 to 300 hours. That is 5 to 7 weeks of full-time work before you have written a single line of code that is unique to your business.
The Real Argument for Building From Scratch
There is one legitimate reason to build from scratch: you need an architecture that is so specific to your product that no existing starter kit can accommodate it.
This is rarely true for early-stage products. At the stage where you are deciding between building and buying, you have not yet validated your product. You do not know enough about what you are building to know what architectural constraints you will face.
Buy the starter kit. Validate the business. If you grow to a point where the architecture genuinely limits you, you will have the revenue to pay for a proper rewrite.
What a Good SaaS Starter Kit Actually Gives You
The value is not just hours saved. It is architecture decisions already made by someone who has thought about them carefully.
Authentication: session management by email, not by database ID. This is a subtle decision that prevents a whole class of bugs. Admin panel: protected by server-side session checking on every route handler. Payments: webhook signature verification, idempotent handlers, metadata for user identification. SEO: generateMetadata on every public page, not bolted on afterward.
These decisions compound. Getting them right from day one means you never have to pay the technical debt tax.
The Flexibility Objection
"But if I buy a starter kit, I am constrained by someone else's decisions."
This is true. It is also true that you are constrained by every decision you make yourself. The question is: which constraints are acceptable for your stage?
A starter kit built on Next.js 14 App Router, TypeScript, Prisma, and PostgreSQL constrains you to a well-supported, widely-used, actively maintained stack. Those are good constraints. The alternative is spending weeks making the same decisions yourself and possibly making worse ones.
