Arattai, a messaging app in India, gained significant traction in September and October 2025, reaching over 5 million downloads on certain days and surpassing established platforms like Telegram and Snapchat. Its rise was supported by media attention, endorsements from government officials, and alignment with Prime Minister Modi's Swadeshi initiative. Union Home Minister Amit Shah's switch to Zoho email led to a 100-fold increase in Arattai's traffic within three days.
The app offers end-to-end encryption for voice and video calls but lacks full encryption for text messages by default. It has a “secret chat” feature and plans to implement comprehensive encryption. User data is stored in Indian data centers, and the app aims to maintain a privacy-focused approach without relying on public cloud providers.
Arattai faces challenges in competing with WhatsApp, which has over 500 million users and offers extensive features such as UPI payments and default encryption. For long-term success, Arattai needs to standardize encryption, enhance its infrastructure, and build an ecosystem with integrated payment solutions and business tools. Overcoming user inertia from WhatsApp, establishing a strong brand identity, and navigating regulatory scrutiny are also critical for its growth.
