Which tech stack is most similar to the MEAN stack?

The MEVN stack is most similar to the MEAN stack because both share the same core components, with only one element differing. The MEAN stack consists of MongoDB, Express.js, Angular, and Node.js, primarily employing Angular for the front-end framework. In contrast, the MEVN stack replaces Angular with Vue.js as its front-end framework, while retaining MongoDB, Express.js, and Node.js in the back-end. This variation focuses on the choice between frameworks, making MEVN directly related to MEAN in terms of architecture and underlying technologies.

Other options, such as MERN, LAMP, and MEAN+, introduce significant changes. MERN swaps Angular for React, representing a different front-end technology stack. LAMP includes entirely distinct technologies—Linux, Apache, MySQL, and PHP—representing a traditional web development stack, which is fundamentally different from the NoSQL and JavaScript-oriented MEAN stack. MEAN+, while closely related, may suggest additional enhancements or variations that don't strictly align with the original MEAN definition, rendering it less directly comparable than MEVN.
