Everything you need to know before buying
I'm Diganta — an indie developer and content creator from Bangladesh. I build Chrome extensions that solve real problems for real people.
I build privacy-first Chrome extensions and educational content for Bengali-speaking audiences. My mission: tools that work silently so you can focus on what matters.
I started building Chrome extensions because I couldn't find tools that fit my workflow as a content creator. Most tools were bloated, required subscriptions, or collected too much data. So I built my own.
What started as personal tools became products other creators needed too. Every extension I ship is something I use daily — built with care, tested thoroughly, and priced fairly.
Starting at just $4.99 with a lifetime license.
Have a question, bug report, or want to say hi? I reply to every message personally — usually within 24 hours.
I'll reply within 24 hours.
