Choosing Your Stack &
Building Better SaaS Apps
The tech stack you choose determines how fast you can ship, how easy it is to maintain, and how much it costs to run as a solo founder. There is no perfect stack — only tradeoffs. This guide breaks down the most popular choices for indie SaaS builders, explains the tradeoffs honestly, and gives you a framework for making decisions that won't haunt you six months from now.
The Right Stack for a Solo Founder
The biggest mistake indie founders make with tech stacks is over-engineering. They pick Kubernetes before they have a hundred users. They set up microservices when they don't even have a micro-product. They choose a database that requires a server before they've validated that anyone will pay for what they're building.
The right stack for a solo founder is the one that minimizes cognitive overhead while maximizing shipping speed. You should be thinking about your product, not your infrastructure. That means choosing tools that have zero setup, great developer experience, and handle the boring stuff for you.
This guide compares the most popular options at each layer of the stack — framework, database, ORM, auth, hosting — with honest pros and cons for each. We also explain why VibePixel uses the stack it does, and at what point you might want to switch to something different.
Six Development Principles for Indie Founders
These principles guide every technology decision we make at VibePixel. They apply to any SaaS you build.
Start with the stack you know, not the stack you should use
The best tech stack is the one you can ship in. You can always rewrite later when you have revenue.
SQLite scales further than you think
For solo founders, SQLite handles everything up to ~$10K MRR. When you need more, Prisma makes it a one-line switch to Postgres.
Never hardcode secrets
Use .env files locally and environment variables in production. AI-generated code loves to hardcode API keys — always review before committing.
TypeScript is non-negotiable
Types give AI tools critical context about your data shapes, API contracts, and component props. It reduces hallucinations dramatically.
Ship the database with your code
SQLite files can be checked into version control for development. Your whole team (or just you) gets the exact same data state.
Use Prisma Studio for debugging
Run npx prisma studio to get a GUI for browsing and editing your database. Faster than writing SQL queries for quick checks.
Why We Chose SQLite + Prisma
When we rebuilt VibePixel from Supabase to a self-hosted stack, we chose SQLite for one reason: it's zero infrastructure. There's no database server to configure, no connection pooling to set up, no backups to schedule. The database is a file that lives next to your code.
Most developers assume they need PostgreSQL because that's what "real" companies use. But for an indie SaaS with less than $10K MRR, SQLite handles everything. It supports concurrent reads, can handle thousands of requests per second in WAL mode, and your entire database fits in a single file you can back up by copying it.
Prisma is the bridge that makes this work. It gives you type-safe queries, auto-generated migrations, and a GUI (Prisma Studio) for browsing data. More importantly, it makes switching databases trivial — when you outgrow SQLite, you change one line in your schema file and run a command. Everything else stays the same.

Frequently Asked Questions
Should I use SQLite or PostgreSQL for my SaaS?
Start with SQLite. It's free, requires zero setup, and handles everything up to ~$10K MRR. When you need more, Prisma makes switching to PostgreSQL a one-line change. Don't optimize for scale you don't have yet.
Next.js vs Remix — which is better for a solo founder?
Either works great. Next.js has a larger ecosystem, more tutorials, and is easier to find talent for later. Remix has better data loading patterns and feels more natural if you understand web fundamentals. You can't go wrong with either.
How do I migrate from Supabase or Firebase?
Use Prisma to define your schema, export your data as JSON, and import it into the new database. The trickiest part is auth — you'll need to migrate user accounts and session data carefully. We wrote a guide on exactly this process.
