In a crowded messaging-app landscape dominated by global giants, Arattai has emerged as a strong domestic contender. Developed by Zoho Corporation, this “Made in India” chat platform is now gaining significant traction — thanks to a surge in adoption, government endorsements, and its promise of privacy and a smooth experience even on low-end devices.
Below is a detailed look at what Arattai offers, how it compares to incumbents, and whether it can become India’s next WhatsApp alternative.
What Is Arattai?
- Developer & Background
Arattai is built by Zoho Corporation, a Chennai-based software company with a long history in business tools and cloud services. (Wikipedia)
The name “Arattai” (அரட்டை) means “chat” or “conversation” in Tamil. (India TV News)
While the app was first soft-launched in January 2021 for internal testing and limited public release, it remained relatively under the radar until recently. (Wikipedia) - Recent Surge in Popularity
In September 2025, Arattai saw explosive growth: daily sign-ups reportedly leapt from ~3,000 to ~350,000 in just three days. (India Today)
The app climbed to #1 in the Social Networking category on the Apple App Store in India. (www.ndtv.com)
Zoho publicly acknowledged the upsurge and is actively scaling its infrastructure to manage the traffic surge. (The Times of India) - Positioning & Intent
Arattai is being positioned as a homegrown alternative to global messaging apps, especially WhatsApp, leveraging themes of data sovereignty, privacy, and domestic technology self-reliance. (Financial Express)
The app is also supported by endorsements from political figures, who have urged users to adopt “secure, free, and made in India” communication tools. (Financial Express)
Key Features of Arattai (What It Offers)
Arattai offers a range of features common in modern chat apps, as well as a few differentiators. Here’s an overview:
| Feature | What Arattai Offers | Notes / Caveats |
| Text & Voice Messaging | Send one-to-one messages, voice notes | Basic but essential |
| Audio & Video Calls | Real-time voice and video calling | Calls are end-to-end encrypted (mint) |
| Group Chats & Channels | Group conversations, channels for broadcasting | Supports large groups (e.g. up to 1,000 members) (The Indian Express) |
| Media & File Sharing | Share photos, videos, documents, media | Expected in any competing chat app (Zoho) |
| Stories / Status | A “stories” section to share updates | Mirrors features found in social and messaging apps (Zoho) |
| Multi-device Support | Use across mobile, desktop, maybe tablets | Sync across devices is claimed (Zoho) |
| Privacy & Data Storage | Data stored on Indian servers, promise of privacy | Voice & video calls are end-to-end encrypted; text messages currently lack full encryption by default (though “secret chats” or enhancements may be in progress) (mint) |
| Additional Tools | “Meetings”, “Pocket”, “Mentions” etc. | Some features that blur line between chat + productivity tools (mint) |
One recent article cites five areas where Arattai outshines WhatsApp: Meetings (built-in meeting support), Pocket (a personal content or note feature), mentions, privacy-first design, and lack of advertisements. (mint)
Another comparative review notes how Arattai is more minimalistic in business features compared with WhatsApp Business (catalogs, payments, etc.), but offers simpler, local-friendly content mechanisms and meeting scheduling abilities. (Digit)
Arattai vs WhatsApp: Where It Stands Out — And Where It Falls Short
Where Arattai Has Advantages
- Homegrown & Data Sovereignty
With all data stored domestically, Arattai taps into rising public and policy interest in “digital autonomy.” (mint) - Calls Encryption & Security Focus
At least voice and video calls are already end-to-end encrypted. (mint) - No Ads & Simpler Monetization
Zoho appears to be positioning the app as ad-free, aiming for trust over ad-based revenue. (The Economic Times) - Low-end Device & Network Friendliness
The founders claim Arattai is optimized to work well even on low-end smartphones and in lower bandwidth environments. (Financial Express) - Integrated Utility Features
Features like built-in meetings, mention tools, content/pocket features help Arattai serve as more than just a chat app. (mint)
Key Weaknesses / Challenges
- Incomplete End-to-End Encryption for Texts
As of now, standard text chats reportedly do not have end-to-end encryption by default, though options like “secret chats” may exist. (mint) - User Base & Network Effect
The biggest challenge for any new messaging app is to get a critical mass of users. Many people already use WhatsApp, and switching cost is high. - Reliability & Infrastructure Scaling
Given the recent sudden surge, Zoho faces pressure to scale servers, reduce outages, latency, and feature bugs. (The Times of India) - Missing Business / Payment Tools
WhatsApp Business has matured features like in-app payments, catalogs, bot integrations, and large-scale API access. Arattai’s comparable business features are more rudimentary for now. (Digit)
Why the Surge? Factors Fueling Arattai’s Popularity
- Timing & Sentiment Shift
Many users have grown more privacy-conscious or dissatisfied with changes and controversies around WhatsApp’s policies. Arattai rode that wave. (The Times of India) - Government Endorsement / “Swadeshi” Appeal
Political leaders and public messaging have encouraged the adoption of “secure, free, India-made” apps, which created buzz and trust. (Financial Express) - Viral Growth & Social Proof
Social media attention, word-of-mouth, and chart-topping app rankings amplified its visibility. (India Today) - Pent-up Demand for Alternatives
Users have long sought trustworthy alternatives to global messaging services, especially Indian-origin ones. Arattai’s promise of local data storage draws from that desire. (Wikipedia)
What’s Next for Arattai & What to Watch Out For
- Roll-out of Full Encryption for Texts
Implementing end-to-end encryption for all chat types is probably the next step for the app to claim full parity with secure messaging standards. - Stability & Performance
As the user base grows, maintaining uptime, sync consistency, and latency across geographies will be crucial. - Feature Deepening & Ecosystem Growth
For mass adoption, features like business tools, payments, integrations, bots, APIs etc. may be added. - Convincing Network Effects
If Arattai can attract influential communities, local businesses, content creators, it can push more users to switch. - Trust & Transparency
Regular audits, transparency reports and clarity on policies will help it gain consumer confidence.
Should You Try Arattai?
If you:
- value Data Sovereignty and prefer Indian-run platforms,
- want a messaging app designed for lighter phones and lower bandwidth,
- are curious about new alternatives to WhatsApp,
then yes — it’s worth experimenting with Arattai. But keep in mind that some features (encryption for text, full business support) are still maturing.
