How to choose a technology stack for SaaS should optimise for hiring, time-to-market and operational familiarity — not Hacker News trends.
A practical default for many B2B SaaS
Next.js or React SPA + Node/Nest or Laravel + PostgreSQL covers most tenancy and billing needs. Add Redis for queues/cache. See Next.js vs React and PostgreSQL vs MongoDB for SaaS.
When to deviate
- Heavy AI/data → Python (FastAPI/Django) services
- Realtime collaboration → Node or specialised infra
- Existing PHP team → Laravel may beat a JS rewrite
- Strict enterprise Java shops → different constraints
Decision criteria ranked
- Can you hire and retain the stack in your city?
- Does the stack have mature auth/billing libraries?
- Can one small team own it end-to-end?
- Is ops tooling familiar (Docker, CI, cloud)?
- Will the choice still make sense at 10× tenants?
Avoid these stack traps
- Polyglot microservices on day one
- NoSQL by default without a relational model need
- Obscure frameworks your next hire has never seen
How we advise clients
We map product constraints to technologies we deliver via SaaS development and web development. Prefer boring technology that ships.
