In a digital world dominated by Meta’s WhatsApp, India’s very own messaging app Arattai has recently become the talk of the town. With millions of downloads and government endorsements, Arattai is positioning itself as a secure, Indian-built alternative that prioritizes privacy and simplicity.
But can it really replace WhatsApp – a global giant with over 2 billion users? Let’s find out.
What Is Arattai?
Arattai (which means “chat” in Tamil) is a messaging app developed by Zoho Corporation, a Chennai-based tech company founded by Sridhar Vembu and Tony Thomas.
It was launched in January 2021, initially as an invite-only app, and by 2025, it has surged to the top of India’s App Store charts after being endorsed by several ministers and influencers.
Arattai aims to provide the same core messaging experience as WhatsApp but built entirely in India – a platform that prioritizes user privacy and independence from foreign data policies.

It quickly became the #1 app in the “Social Networking” category on India’s App Store, surpassing WhatsApp and Telegram in weekly installs.

As encryption and global rollout improve, Arattai could become India’s answer to WhatsApp – a true homegrown success story.
