A recommended 2026 SaaS stack
| Layer | Recommended | Why |
|---|---|---|
| Backend | Ruby on Rails | Fastest path to a working product |
| Database | PostgreSQL | Reliable, powerful, scales far |
| Frontend | Hotwire + React where needed | Simple by default, rich when required |
| Payments | Stripe | The standard for SaaS billing |
| Background jobs | Sidekiq / Redis | Handles async work reliably |
| Hosting | A simple managed host | Less ops, more shipping |
Why boring tech wins
The best stack is the one your team ships fastest in and can maintain for years. Mature, battle-tested tools have answers to every problem, huge communities, and fewer surprises. Chasing the newest framework usually trades short-term excitement for long-term pain.
When to reach for more
Add specialized tools only when a real need appears — for example, Elixir/Phoenix for real-time features at scale, or React Native to ship a mobile app from shared code. Right tool, right job, not by default.
Our stack
We build on Rails + PostgreSQL, add React where interactivity demands it, use Stripe for billing, and reach for Elixir when real-time scale calls for it. It's the stack behind our seven live products. See how we build SaaS.
