History
Arattai, a homegrown Indian messaging app developed by Zoho Corporation, began development in 2018 and was officially launched in 2021 after several years of investment in infrastructure and performance improvements. It aims to provide a secure and private communication tool with Indian servers and no data-selling policies. Zoho’s founder Sridhar Vembu adopted a patient capital approach, building the company without external funding and focusing on long-term independence and value creation.
Arattai’s rise gained significant momentum in 2023, receiving high-profile endorsements from Indian government officials, including IT Minister Ashwini Vaishnaw and Education Minister Dharmendra Pradhan. These endorsements framed Arattai as part of the broader “Atmanirbhar Bharat” (Self-Reliant India) initiative, promoting indigenous technology platforms to reduce dependence on foreign tech giants amid geopolitical tensions and US tariff issues. The government’s backing signals a shift in India’s technology policy, emphasizing digital sovereignty, economic self-reliance, and national security.
The government’s promotion of Arattai enhances the app’s visibility and credibility and aligns with campaigns like “Digital India” that push for local alternatives to global technology products. This has helped Arattai tap into growing demand for digital sovereignty with a patriotic edge. Despite its emphasis on privacy and security, founder Sridhar Vembu has acknowledged that while the app allows private communication, users should not expect it to completely shield them from legal government reach, referring to it as a “secret rebel” platform.
The platform’s infrastructure continues to scale to support rapid growth, with plans for further major announcements hinted at by Vembu. The surge in user adoption indicates readiness among Indian users to embrace a domestically produced messaging alternative balancing privacy, security, and rich functionality.
Features
Arattai is a feature-rich Indian messaging app developed by Zoho, designed as a comprehensive and secure communication platform tailored for diverse user needs, particularly in India’s low-bandwidth and low-resource environments. It combines traditional messaging functions with unique enhancements and social media-inspired elements, aiming to provide a versatile alternative to global apps like WhatsApp.
Messaging and Communication
The app supports voice and text messaging, document and image sharing, and high-definition audio and video calls optimized for low-bandwidth conditions, ensuring usability on 2G and 3G networks and older smartphones. Group chats can accommodate up to 1,000 participants, surpassing many competitors, and users can create dedicated channels for broadcast-style communications aimed at larger communities or organizations.
Video Meetings
Arattai includes a dedicated “Meetings” feature accessible from a bottom dock, allowing users to start instant video calls, join ongoing meetings, or schedule future sessions. This functionality rivals popular platforms like Zoom and Google Meet and fills a gap left by WhatsApp, which currently lacks a dedicated meeting scheduling feature.
Privacy and Security
The app employs end-to-end encryption (E2EE) for voice and video calls, ensuring secure real-time communication. Text messages are not yet fully protected by default E2EE; secure “secret chats” offer encrypted messaging, while a broader rollout of end-to-end encryption for all chats is underway. Arattai stores all user data locally on Indian servers, aligning with digital sovereignty goals and maintaining strict no-data-monetisation policies to protect user privacy. Experts have raised concerns about the absence of default E2EE for all messages and potential government access under current regulations.
Unique Functionalities
Arattai introduces innovative features enhancing user experience and organization:
– Mentions: Aggregates all messages where a user is mentioned, regardless of chat or group, simplifying message tracking.
– Pocket: A personal self-chat space to store photos, videos, notes, reminders, and other files for personal organization, akin to WhatsApp’s “You” chat window but with broader capabilities.
– Channels and Stories: Social media-style broadcasting with Channels for following updates from groups or communities and Stories for sharing ephemeral content, mirroring similar features on WhatsApp and others.
– Location Sharing “Till I Reach”: Lets users share real-time location until arriving at a specified destination, offering enhanced safety and convenience.
Accessibility and Performance
Designed for accessibility, Arattai functions smoothly on low-end smartphones and slower internet connections, including rural areas with limited network infrastructure. Its lightweight architecture consumes less data and system resources compared to competitors like WhatsApp, making it suitable for budget-conscious users and those in under-served regions.
Collectively, these features position Arattai as a privacy-conscious, locally hosted messaging app focused on serving India’s diverse communication needs while fostering a domestic technology ecosystem.
Market and User Base
Developed by Chennai-based Zoho Corporation, Arattai rapidly emerged as a prominent player in the Indian messaging app market following a surge in adoption during 2025. India, WhatsApp’s largest market, presented fertile ground for Arattai as a homegrown alternative. Initially launched in January 2021 with modest awareness and fewer than 10,000 downloads by August 2025, the app experienced dramatic growth after September 2025, driven by privacy concerns around WhatsApp’s updated terms and renewed emphasis on data sovereignty.
The user base is predominantly Indian, with over 95% of monthly active users residing in India as of September 2025. Arattai recorded seven million downloads in a single week, with daily sign-ups skyrocketing from approximately 3,000 to over 350,000 in three days. This surge propelled Arattai to the top position in the Social Networking category on Apple’s App Store in India and nearly into the top 100 on Google Play.
Growth was strongly influenced by government endorsements, including support from Education Minister Dharmendra Pradhan and others advocating indigenous digital solutions under Atmanirbhar Bharat. This patriotic framing and emphasis on local data storage—keeping all Indian user data on servers within India—resonated amid rising concerns over privacy and data localization. The surge reflected a broader shift in Indian consumers’ priorities, factoring data sovereignty and nationalistic pride into technology choices.
Despite initial uptake, Arattai faced challenges retaining users after the enthusiasm wave. By early November 2025, downloads dropped from nearly 13.8 million in October to under 200,000, with monthly active users declining to about 4 million, indicating difficulties sustaining long-term engagement. Nonetheless, the rapid rise highlighted a critical moment in India’s digital ecosystem, where domestic innovation and government-backed initiatives gained unprecedented traction in messaging apps.
Arattai’s market position is also distinguished by its tailored approach to India’s linguistic diversity and technological constraints, offering document and image sharing, voice and text messaging, audio and video calls, and large group chats with up to 1,000 participants. Combined with alignment with national digital sovereignty goals, this positions it as a key contender reshaping India’s messaging app landscape.
Impact and Reception
Arattai has gained attention as a domestic alternative to WhatsApp, aligning with India’s push for digital sovereignty under initiatives like “Digital India” and “Atmanirbhar Bharat”. Its positioning as a “Made-in-India” product appeals to users seeking local solutions that reduce dependence on foreign technology giants, bolstered by government endorsements increasing its visibility and credibility.
The app’s impact is reflected in its growing user base, with a reported 100x increase in daily sign-ups, indicating strong early interest among Indian consumers seeking a patriotic and privacy-conscious messaging option. Use of local servers and a strict no-data-selling policy respond to concerns about surveillance capitalism and foreign data exploitation, resonating with nationalistic sentiment.
Despite its promising start, Arattai has faced scrutiny regarding its privacy and security framework. Unlike established competitors such as WhatsApp, Signal, and Telegram, Arattai currently lacks default end-to-end encryption (E2EE) for messages, a key feature for secure communication. Developers have acknowledged this limitation and stated implementing E2EE is an active priority. This gap has led to hesitation among privacy experts and users, with concerns about government data demands, especially given Zoho’s close ties to the Indian government and the app’s public promotion by federal ministers.
Functionally, Arattai introduces unique features enhancing user experience, such as “Pocket,” personal cloud storage for messages and media accessible across devices, expanded group chat capacity supporting up to 1,000 participants, and dedicated channels for larger communities. Its Meetings feature offers video calling capabilities that surpass WhatsApp’s, enabling instant calls, scheduled meetings, and multi-participant video chats, providing competitive functionality in a rapidly evolving market.
Industry observers view Arattai as part of a larger trend where Indian tech companies are transitioning from consumers to creators of world-class products, with Zoho exemplifying this shift. Challenges remain in overcoming entrenched global platform network effects and addressing privacy concerns to gain sustained trust and adoption.
Controversies and Criticisms
Despite official endorsements and growing popularity, Arattai has faced criticisms centered on privacy and competitive challenges. Experts and analysts attribute its struggle to build a significant user base to privacy concerns, lack of differentiation, intense competition, and weak network effects. This raises skepticism about its ability to fully challenge dominant messaging giants like WhatsApp.
A main contention involves data privacy and encryption. While offering E2EE for video and voice calls, Arattai does not currently extend this to text messages, raising concerns about message traceability and privacy. The Indian government’s insistence on message traceability for security conflicts with E2EE practices common in global messaging platforms. Shashidhar KJ, managing editor at MediaNama, notes traceability can be implemented without full E2EE, reflecting tension between security and privacy in India.
Arattai’s data handling has also been scrutinized. Although data is stored within India and conversations encrypted in storage, the app collects usage statistics—including events, APIs, crash reports, and session data—based on user preferences. Collection of unique device and account IDs, internal and inaccessible to third parties, raises privacy questions given India’s distinct data norms compared to the US and Europe. Company representatives emphasize transparency, compliance with local IT rules, and user control over data.
Additionally, Indian apps like Arattai face an uphill battle against established global competitors with entrenched user habits and extensive resources. Dominance of platforms such as WhatsApp and Facebook challenges newer entrants seeking a domestic messaging revolution. These dynamics, combined with privacy controversies and regulatory pressures, fuel debate about Arattai’s long-term viability and role in India’s digital landscape.
Future Plans and Developments
Under development since 2018 and officially launched in 2021, Arattai is poised for significant growth and feature enhancements as part of its long-term vision. The company continues investing in performance upgrades and infrastructure to support a major forthcoming announcement, signaling platform expansion and evolution.
A key focus is implementing end-to-end encryption (E2EE) for all communication modes. Currently offering E2EE for calls and video chats and a ‘secret chat’ option for secure messaging, full encryption for standard text chats is in active development and expected soon. Zoho’s team has acknowledged privacy concerns and committed to prioritizing data security, aiming to accelerate this critical feature’s launch.
Beyond features, Arattai’s growth aligns with India’s strategic push toward technological sovereignty and digital self-reliance. Supported by initiatives like “Digital India” and “Atmanirbhar Bharat,” it aims to reduce dependence on foreign tech giants by promoting indigenous alternatives that safeguard privacy and national security. Government endorsement reflects a policy shift emphasizing homegrown innovation and economic self-reliance in technology.
Looking ahead, Arattai is expected to scale infrastructure to handle exponential user growth while evolving into a robust communication ecosystem meeting privacy-conscious Indian users’ demands. Founder Sridhar Vembu indicates more plans, underscoring a patient, value-driven development approach prioritizing long-term sustainability over rapid commercialization. As Arattai matures, it is positioned to serve domestic needs and contribute to the global emergence of Indian tech products with world-class capabilities.
