Best Tools for Launching a SaaS
A SaaS in 2026 needs five things to ship: hosting, a database, payments, auth, and product analytics. Anything else is optional or replaceable. Here is the stack that gets you there with the lowest total cost of ownership.

Common questions
What is the cheapest way to launch a SaaS in 2026?
Vercel free tier + Supabase free tier + Stripe (no monthly fee) gets you to production for under $10/month even with a custom domain. The cost only grows with usage, which is what you want.
Do I need Linear if it is just me?
Probably not. A todo list works for solo founders. Linear earns its keep when you have a second engineer, paying customers asking for features, or a roadmap stakeholders need to see.
When should I add product analytics?
Day one if you can. PostHog free tier covers up to 1M events and the data compounds. Adding analytics six months later means six months of decisions made without data.
