Over years ( I built my first website in 1998 ) I have encountered and used many tools, frameworks and technologies, but if I had to point to my most tried and tested set of tools, it would be what is commonly known as the LAMP stack. LAMP stands for Linux (in my case it has been Debian GNU/Linux for well over 20 years now), Apache, MySQL and PHP. These days I develop stuff with OOP MVC Web frameworks like CodeIgniter 4 ( earlier also CodeIgniter 3 and Kohana ).
Since 2020 I have tried a bit of Django and Flask (Python backend), as well as MERN stack (MongoDB, Express, React, Node.js).
On the frontend side jQuery and Bootstrap 4 have been my tools of choice for some time years.
Here is a Frontend/Backend breakdown of technologies I use for web development.
