Developed by the acclaimed Zoho Corporation, Arattai was launched in 2021 and quickly became a trusted alternative to internationally-dominated chat platforms, such as WhatsApp. As of 2025, Arattai has exploded in popularity, driven by high-profile endorsements and a strong focus on privacy, reliability, and user-centric features. This article offers an in-depth look at Arattai, its growth story, features, technical backbone, impact on India’s digital independence movement, and reasons behind its success.

Arattai’s Origins: The Vision Behind the App
Zoho Corporation, a homegrown Indian tech giant with a global footprint, initially developed Arattai to address three critical needs in India’s digital communication scenario: data privacy, affordability, and accessibility for all device types – especially low-end smartphones and patchy network areas. The app embodies the spirit of “Aatmanirbar Bharat” (self-reliant India), aiming to provide a locally-made messaging service without dependence on foreign entities. Backed by serial entrepreneur Sridhar Vembu, Arattai quickly harnessed Zoho’s deep R&D strengths and market understanding.
Key Features of Arattai
End-to-End Voice and Video Calls: Arattai supports crystal-clear calls over varying network strengths and device capabilities.
Group Chats and Broadcast Channels: Users can create large groups, share media, and broadcast messages efficiently.
Media Sharing: Supports photos, videos, document attachments, voice notes, and GIFs for rich communication.
Stories and Status Updates: Modern features for sharing ephemeral content, akin to Instagram or WhatsApp status.
Localized User Interface: Optimized for Indian languages and regional needs.
Low-Bandwidth Optimization: Designed to work smoothly on low-end devices and slower internet connections.
Encryption: All calls are end-to-end encrypted, with chat encryption rolling out soon for even greater privacy.
Security and Privacy: How Arattai Keeps Your Data Safe
Security is a top priority for Arattai. Calls are already end-to-end encrypted, meaning the content remains private between users, and even the app provider cannot intercept communications. Zoho regularly updates the infrastructure to support robust chat encryption, safeguarding text, media, and group messages. Data is stored and managed exclusively within India, complying with national regulations and offering peace of mind to privacy-conscious users.
Technical Strengths: Indian Engineering at Its Core
Arattai leverages Zoho’s mature cloud-first development framework, which allows seamless scalability and rapid feature rollouts across the app’s user base. The backend is equipped with distributed servers and local data centers to support emergency surges (such as when daily sign-ups jumped from 3,000 to 350,000 within days after ministerial endorsements). The tech stack is optimized for high reliability, secure login, rapid media processing, and robust network adaptability, ensuring the app can support millions of concurrent users without service interruptions.
Growth Trajectory: From Underdog to Leader
In 2025, Arattai’s daily downloads soared after endorsements from major government officials, who championed a Swadeshi (Made-in-India) technology stack. The app hit #1 in the social networking category on Apple’s App Store India practically overnight. This unprecedented growth led Zoho’s team to scale up infrastructure rapidly, doubling development resources and support staff to keep up with surging demand.
Cultural Impact: Swadeshi, Digital India, and Citizen Trust
Arattai’s rise is more than a tech success; it is emblematic of a larger movement towards digital self-reliance in India. With increasing concerns around data sovereignty and privacy abuses by foreign platforms, Arattai’s commitment to being an Indian product — with all data, infrastructure, and compliance rooted within India — resonates deeply with both government policy and citizen sentiment. The app has become a poster child for the Aatmanirbar Bharat initiative, validating the need for robust domestic alternatives to global tech giants.
