Well, for me top 5 favorite programming tools/ software are
1. Bootstrap
2. Github
3. HTML5 Builder
4. Geek
5. Codepen
and many others, according to one's own preferences.
The most preffered online gateway/app I prefered to use now is PhonePe and sometimes Paytm. Earlier I used to prefer Gpay only but it is not working fine now, many times payment got stuck, although it was and it is fast.
