Web development tech stacks refer to the combination of programming languages, frameworks, libraries, and tools used to build web applications.
There are various tech stacks available, but the choice of a particular tech stack depends on the requirements of the project, scalability, performance, and development time.
Some of the popular web development tech stacks include: 
LAMP
LAMP stands for Linux, Apache, MySQL, and PHP. This stack is used to build dynamic web applications. A widely-used open-source stack for building dynamic web applications.
MEAN
MEAN is an acronym for MongoDB, Express.js, AngularJS, and Node.js. A popular stack for building full-stack JavaScript web applications.
MERN
MERN stands for MongoDB, Express.js, React.js, and Node.js. A variant of MEAN, but with React instead of AngularJS.
PERN
PERN is an acronym for PostgreSQL, Express.js, React.js, and Node.js. A full-stack JavaScript-based framework that allows developers to build web applications quickly and efficiently. This stack is similar to MERN, but it uses PostgreSQL as the database management system instead of MongoDB.
MEVN
MEVN stands for MongoDB, Express.js, Vue.js, and Node.js. A full-stack JavaScript-based framework that enables developers to build web applications rapidly.
Overall, these tech stacks offer a range of options for developers to choose from, based on their needs and preferences.
