A Web development stack or tech stack consists of a set of web frameworks, programming languages, servers, and databases that when combined help in producing seamless, fully-fledged web applications. Choosing the right stack is crucial because this determines the speed, security, scalability, and overall efficiency of your app.

Here are the best and most popular tech stacks:

1. MERN STACK

This stack consists of:

• MongoDB: NoSQL database
• ExpressJs: A nodeJs backend framework
• React: A frontend Javascript library
• NodeJs: Javascript runtime-environment

2. MEAN STACK

This stack is quite similar to MERN except that it uses Angular instead of React.
Technologies:

• MongoDB: NoSQL database;
• ExpressJs: A nodeJs backend framework
• Angular: A frontend Javascript library
• NodeJs: Javascript runtime-environment

3. LAMP STACK

• Linux: Open-source operating system
• Apache: Free and open source HTTP web server
• MySQL: Relational database Management System
• PHP: Backend language

4. SERN STACK

• SQL: Language of relational databases
• ExpressJs
• React
• NodeJs

5. Vue.js STACK

• Vuejs: A frontend javascript framework
• NodeJs
• MongoDB
• ExpressJs

6. SERVERLESS STACK

• AWS lambda: According to Amazon, is an event-driven serverless computing platform provided by Amazon
• API Gateway: As per Nginx, it receives and directs client API requests, effectively routing them to the relevant Microservice using techniques such as request routing, composition, and protocol translation.
• DynamoDB: NoSQL database by Amazon designed to run high performance applications at any scale
• React: Frontend library

7. ASP.NET STACK

• ASP.Net: Microsoft framework for building web apps with .NET and C#
• C#: programming language
• SQL Server: Relational database

8. JAVA STACK

• Java: Programming language
• Spring boot: Java framework
• MySQL/PostgreSQL: Relational Databases

9.Ruby on Rails

• Ruby: programming language
• Rails: Ruby Framework
• SQLite: C library that has a server and database

10. JAMstack

• Javascript: programming language
• API: Application Programming Interface
• Markup: Generated by static site generators like Jekyll, Gatsby, etc

In conclusion
The choice of a tech stack really boils down to what you want to achieve. Some of the factors to consider are scalability, security, cost and availability of integration tools, and ease of solving a problem.
