Founders often ask us: React or Vue? Node or Python? The right answer depends on your team, timeline, and what you're building — not what's trending on Hacker News.
We recommend starting with three questions: Who will maintain this after launch? What integrations do you need in the first 90 days? How many concurrent users do you expect in year one?
Our default recommendations
For most B2B SaaS products: Next.js + PostgreSQL + a managed cloud host. For data-heavy dashboards: React + FastAPI + Redis. For mobile-first consumer apps: React Native or Flutter with a REST or GraphQL backend.
The stack matters less than clean architecture, automated tests on critical paths, and documentation your next developer can read.
