A homegrown challenger is rising in India’s messaging market — and it wants to take on WhatsApp. Over the past few weeks, Arattai, a chat app developed by Indian tech company Zoho, has exploded in popularity, fueled by a surge of national pride and government endorsements.
The app — whose name means “banter” in Tamil — was quietly launched in 2021, but only recently went viral. According to Zoho, Arattai recorded seven million downloads in a single week, a meteoric rise from fewer than 10,000 installs in August, as per data firm Sensor Tower.
Government Push Spurs A Homegrown Boom
Arattai’s sudden success is being closely tied to the Indian government’s renewed “Make in India, Spend in India” campaign, emphasizing domestic innovation in the wake of fresh U.S. trade tariffs. Several federal ministers, including Dharmendra Pradhan, have publicly urged citizens to support Indian-made digital platforms.
Zoho CEO Mani Vembu acknowledged that this official backing played a major role in the app’s surge. “In just three days, we saw daily sign-ups jump from 3,000 to 350,000,” he said. “It shows that users are enthusiastic about a homegrown product that can meet their unique needs.”
Despite the buzz, Arattai’s active user count remains far behind WhatsApp’s 500 million monthly users in India — Meta’s largest global market.
Familiar Features, Local Pride
Functionally, Arattai mirrors WhatsApp. It offers instant messaging, voice and video calls, and business tools for small enterprises. Like WhatsApp, it’s optimized to work smoothly even on low-end smartphones and slower internet connections — a crucial advantage in a price-sensitive market.
Early users have praised its clean interface and ease of use, with many highlighting the pride of using an “Indian-made” alternative. Yet experts caution that emotional appeal alone may not sustain growth.
“Arattai’s real test will be retaining users after the initial wave of patriotic downloads,” said Delhi-based tech analyst Prasanto K. Roy. “Breaking through WhatsApp’s massive network effect — where everyone’s already there — is a monumental challenge.”
Data Privacy And Regulatory Pressures
Privacy, however, may become Arattai’s biggest hurdle. While the app supports end-to-end encryption (E2EE) for voice and video calls, it does not yet extend encryption to text messages — a gap that raises questions about user data protection.
Technology policy experts note that India’s government has pushed for traceability of messages in the name of national security, a requirement that can conflict with full encryption.
“Without E2EE for messages, traceability becomes easier but privacy weaker,” said Shashidhar K.J., managing editor at MediaNama.
Vembu said Zoho is working to roll out full encryption “as quickly as possible,” explaining that the company accelerated Arattai’s launch ahead of schedule. “Once E2EE is implemented, even we won’t have access to the content of conversations,” he added.
Can Arattai Compete?
The battle ahead is steep. Apps like Koo (billed as India’s answer to X) and Moj (a TikTok alternative) initially saw explosive growth but soon faded. Even ShareChat, once seen as a serious WhatsApp rival, has scaled back ambitions.
Beyond user acquisition, Arattai will need to prove it can stand firm against government data requests — something global players like Meta and X have challenged in court. Experts say Zoho, as an Indian company, may face greater pressure to comply.
“Arattai’s success will depend not only on features but on its independence and users’ trust in its privacy stance,” said legal expert Rahul Matthan.
For now, Arattai’s rise reflects India’s growing confidence in building world-class tech alternatives. But whether it can truly dent WhatsApp’s dominance — or simply become another short-lived contender — remains an open question.
