Quranwbw.com is a Quran website with word by word translation, transliteration in English, Urdu, Hindi, Indonesian, Bangla, Turkish and Tamil. You can also listen to how a word is pronounced and also listen to ayah recitations.
The actual website code is still not open source but will be in the future In Sha Allah.
Production Site: https://quranwbw.com
Development Site: https://dev.quranwbw.com
Quranwbw.com uses Javascript (jQuery), PHP and Node.js for development and just Javascript (jQuery) in the production. I like keeping it simple and don't have any plans to use any other frameworks.
