10 tools scored · 7 dimensions
A SaaS stack is the set of infrastructure tools — database, deploy, payments, email, and auth — that power a web application. The right stack lets a solo developer ship and run a product that would have taken a team a few years ago.
Every tool in this category earns its place by solving one specific infrastructure problem well, having a generous free tier for validation-stage projects, and scaling without forcing a rewrite. The scores focus on developer experience, free tier generosity, scalability, and what happens to your costs as you grow.

Free Tier and DX scores matter most. Supabase, Vercel, and Resend all have free tiers that cover meaningful usage before you earn any revenue.

No — you need what your product needs. Most SaaS products need a database, a deploy platform, and a payment processor. Auth is optional if Supabase's built-in auth covers your needs. Email is only needed for transactional messages. Start with the minimum and add as needed.
Effectively $0 if you use free tiers. Supabase (free), Vercel (free hobby tier), Stripe (no monthly fee, 2.9% + 30¢ per transaction), Resend (3,000 emails/day free), Clerk (10k monthly active users free). You only start paying meaningfully when you have real users.
Supabase uses Postgres — the industry standard relational database — versus Firebase's NoSQL document model. Postgres is more flexible for complex queries, has better tooling, and does not lock you into Google's infrastructure. Supabase is also open source and self-hostable if you ever want to move.
Vercel's pricing can be a concern at very high traffic — some teams have moved to Cloudflare Workers or self-hosted Next.js at significant scale. For most indie SaaS products under $50k MRR, Vercel Pro at $20/mo is fine and the DX is worth it.
Stripe gives you more control and better integrations, but you are responsible for VAT compliance across countries. Paddle and Lemon Squeezy act as Merchant of Record — they handle VAT collection and remittance globally. If you are selling to European customers and do not want to deal with VAT, Lemon Squeezy is worth the slightly higher fees.
How these scores are calculated
SaaS stack scores are based on free tier limits from official pricing pages, developer experience ratings from the Indie Hackers community, Stack Overflow Developer Survey results, official SLA documentation, documentation quality assessments, and community activity (GitHub stars, Discord size, Stack Overflow question volume). Scores reflect the perspective of a solo or small-team developer building a web product.
