Arattai Messenger vs WhatsApp: accessibility edge meets end-to-end encryption deficit

Arattai Messenger’s rapid rise: Android TV support, rural reach, and a security gap

Arattai Messenger

Arattai Messenger, Zoho’s India-built messaging app, has rocketed past 5 million downloads within days of launch, vaulting into the global charts and momentarily outpacing heavyweights such as Telegram, Messenger, and Snapchat in October 2025’s download race. The spike underscores a mix of local pride, appetite for lean, data-efficient tools, and growing interest in alternatives to WhatsApp.

What’s driving the breakout

  • Built for low-end phones and weak networks: Arattai (“chat” in Tamil) is engineered for low bandwidth and modest hardware, ensuring texts and calls remain usable where connectivity falters.

  • Cross-device reach: Beyond phones, Arattai ships with an Android TV app, a niche yet notable differentiator that WhatsApp still lacks.

  • ** SMB-friendly positioning:** Its efficiency and reliability make it a plausible lightweight enterprise messenger for small organizations that can’t afford data-hungry stacks.

The product pitch

Arattai delivers the baseline playbook—text, voice and video calls, and file sharing—wrapped in a compact client that minimizes resource consumption. That formula has resonated in rural and semi-urban markets, where inconsistent service and pricier data often exclude users from fully featured platforms.

The catch: encryption isn’t end-to-end (yet)

Despite encrypted voice and video calls, Arattai does not currently offer full end-to-end encryption for text chats. Zoho leans on localized data storage and pledges not to share user data externally, but server-side access remains theoretically possible—a red flag for privacy advocates and a competitive gap versus rivals whose E2EE is table stakes.

Sustainability: can the momentum hold?

Early traction is impressive, but retention will hinge on:

  • Security roadmap: Clear timelines toward E2EE for messages and transparent audits.

  • Feature depth vs. simplicity: Adding just enough capability without bloating the app.

  • Network effects: Converting curiosity-driven installs into active daily use—especially outside India.

Bottom line: Arattai’s speed, simplicity, and inclusivity are timely—and genuinely useful. But to graduate from breakout hit to credible WhatsApp rival, it must close the encryption gap and prove staying power beyond the launch halo.
