Top 8 Most Popular Web Frameworks to Use in 2021

Web frameworks play a vital role in building robust and interactive web applications for both frontend and backend. If we were to talk about some of the most popular web applications, the prominent names would be Netflix, Facebook, LinkedIn, and YouTube. These tech giants have set an example of how web apps should be built.

Companies wanting to achieve such magnanimous success often end up replicating the entire tech stack of these tech giants. However, one must note that what works for them might not work for you. And that every web app framework isn’t suitable for all kinds of use cases.

It is intended to keep the core simple but extensible. After all, it supports extensions by letting developers add libraries and plugins to web apps like it was implemented in this framework. It’s a highly lightweight framework, which is gradually climbing the charts and gaining attention due to its flexibility.
