Arattai Messenger by Zoho: The Indian WhatsApp Alternative Taking the Market by Storm

What is Arattai Messenger, and why is everyone suddenly talking about it? Over the last few weeks, the app has exploded in popularity, crossing 350,000 daily sign-ups in just three days. Marketed as the “Indian WhatsApp”, Arattai has not only challenged Meta’s dominance but also sparked a renewed conversation about India’s need for digital self-reliance.

At its core, Arattai is a messaging app built by Zoho Corporation, one of India’s most respected software companies. But it’s more than just another chat app - it’s part of a larger narrative around privacy, independence, and the rise of Indian-built consumer technology.

What is Arattai Messenger and Why Is It Called the Swadeshi WhatsApp?

Arattai Messenger is a free communication app that allows users to send messages, share photos and videos, and make voice and video calls. The word “Arattai” comes from Tamil, where it means “chat” or “conversation” or “banter.” It is pronounced as “Uh-rah-ttai” with emphasis on the double ‘t’.

The app has been dubbed the Indian WhatsApp for two key reasons:

1. Feature similarity - Much like WhatsApp, Arattai offers instant messaging, calling, media sharing, and group chats.

2. National identity - Unlike WhatsApp, which is owned by Meta, Arattai is a homegrown product by Zoho, headquartered in Tamil Nadu.

This identity resonates with many Indians who are increasingly skeptical of foreign-owned platforms controlling their data. The “Indian WhatsApp” label has given Arattai a strong positioning against rivals like WhatsApp, Telegram, Signal, and Hike.

Where Hike once tried to win the Indian market with stickers and local features, it failed to sustain itself. Telegram and Signal appeal to more privacy-conscious users but lack mainstream adoption in India. Arattai has an advantage: it combines WhatsApp’s familiarity with Hike’s Indian flavor, all backed by Zoho’s reputation.

Who is the Founder & Owner of Arattai? The Story of Zoho and Sridhar Vembu

Arattai is owned by Zoho Corporation, a global SaaS giant that has quietly built one of the most successful Indian tech empires. Founded by Sridhar Vembu, Zoho is best known for its enterprise software suite used by millions of businesses worldwide.

Sridhar Vembu, a Padma Shri awardee, has long advocated for digital independence. His decision to base Zoho’s headquarters in rural Tamil Nadu reflects his belief that world-class technology can be built outside the usual hubs. Arattai fits into his philosophy of “Made in India, for the world.”

In his vision, Arattai isn’t just a product, it's a statement against overreliance on foreign tech giants. At a time when WhatsApp’s data-sharing policies with Meta have raised concerns, Zoho is offering a trustworthy alternative rooted in Indian soil.

Data Privacy and End-to-End Encryption: Does Arattai Deliver?

When it comes to messaging apps, one of the biggest questions is always about encryption and data protection. WhatsApp, Telegram, and Signal all claim to offer secure messaging - but their approaches vary.

So, where does Arattai stand?

• End-to-End Encryption (E2EE):
  Arattai provides end-to-end encryption for video chat and calls, meaning only the sender and recipient can read them. However, messages are not end-to-end encrypted. Leaving a significant hole in its security measures. Zoho says chat E2EE is planned/under development. Leaving it behind WhatsApp in terms of security measures.

• Data Storage:
  Unlike WhatsApp, which stores user data on servers abroad, Arattai keeps its data within India. This aligns with Indian data sovereignty laws and gives users more confidence in how their information is handled.

• No Ads, No Data Selling:
  Sridhar Vembu has emphasized that Arattai, like all Zoho products, will not run on an ad-driven model. That means no profiling, no data selling, and no hidden monetization through user surveillance.

In short, Arattai positions itself as a privacy-first platform, an area where WhatsApp has repeatedly stumbled in India.

Arattai Features & Benefits

While Arattai looks and feels familiar to anyone who has used WhatsApp, it also brings in unique elements tailored for Indian users.

Messaging and Calling

Arattai supports one-on-one chats, group messaging, voice notes, voice calls, and video calls. Call clarity is optimized even for low-bandwidth Indian internet connections, making it practical for rural users.

Arattai Web

The app isn’t limited to mobile. Arattai Web allows users to log in from a browser, just like WhatsApp Web, making it easier to work across devices.

Cultural Relevance

Zoho has designed Arattai with local languages, stickers, and Indian themes. Where WhatsApp feels generic, Arattai feels rooted in Indian culture.

Cross-Device Sync

Messages are synced across devices, ensuring continuity whether you’re on phone or desktop.

Business Use Cases

Zoho is hinting at integrating Arattai with its broader suite of business collaboration tools, which could open up enterprise-grade adoption in the future.

Explosive Growth: Crossing 350,000 Sign-ups

One of the most remarkable aspects of Arattai’s rise is its viral adoption curve.

• Within three days, daily sign-ups jumped from 3,000 to 350,000 - a 100x growth spike.

• This surge came amid rising concerns about WhatsApp’s privacy policies, showing how timing worked in Arattai’s favor.

The app’s positioning as the “Swadeshi WhatsApp” has struck a chord with users. While Signal and Telegram remain popular with niche audiences, Arattai’s homegrown identity gives it mainstream appeal.

However, challenges remain. Competing against WhatsApp’s 500 million Indian users will not be easy. For Arattai to succeed, it must:

• Maintain trust by keeping privacy promises.

• Scale to handle millions of daily active users.

• Continuously innovate features to match or surpass global rivals.

Arattai vs WhatsApp vs Signal

Review of Arattai, Will it Break the Western Monopoly?

For years, apps like WhatsApp (Meta) have dominated India’s digital communication. With over 500 million Indian users, WhatsApp holds a near-monopoly in messaging.

One of the biggest hurdles for Arattai is not features but habit. In India, the word WhatsApp has become almost synonymous with messaging - much like Xerox for photocopying or Colgate for toothpaste. Convincing users to migrate from an entrenched daily-driver app is an uphill challenge.

While nationalism and the “Made in India” tag have given Arattai an initial boost, that wave won’t sustain it for long. For lasting success, the app must be better than WhatsApp and Signal, not just local. Even Telegram and Signal, despite years in the market, haven’t managed to replace WhatsApp in India.

Adding to this, Arattai is still in an early development phase. Reports suggest UI lag, missing refinements, and partial encryption (with full chat E2EE still in the works). Zoho was planning a grand launch in November, but an unexpected endorsement by the Education Minister forced the team into an emergency scale-up to handle the sudden surge in users.

Ultimately, how Zoho promotes, polishes, and differentiates Arattai will decide whether it becomes a real challenger or just another app in the crowded messaging space

The Future of Arattai and the Role of Zoho

Zoho has always thrived as a B2B SaaS powerhouse, but Arattai marks one of its first major pushes into consumer tech. If successful, it could pave the way for Zoho to challenge global players not just in business software but also in consumer communication platforms.

The roadmap may include:

• Advanced collaboration tools integrated with Zoho Workplace.

• Enterprise-ready encrypted chat solutions for businesses.

• AI-driven personalization for smarter messaging.

Arattai is not just a consumer play, it may well become the bridge between Zoho’s SaaS dominance and India’s consumer internet ambitions.
