What are the differences between MERN, MEVN, and PERN stacks, and when is MERN the best fit?

Compares stacks (React vs Vue frontends; NoSQL vs SQL backends) and explains when choosing MERN makes sense for modern apps.

• MERN uses React on the frontend; MEVN uses Vue; PERN uses PostgreSQL instead of MongoDB. • MERN is preferred for applications needing React’s ecosystem, integration with React Native, component reuse, and strong hub in developer jobs. • MEVN is lightweight and beginner-friendly, while PERN provides relational integrity and SQL advantages when needed.
