The government's 2025 order to block the platform was based on the grounds that the content lacked meaningful storyline or social messaging and was essentially "soft porn". Platforms like Kooku, Ullu, and ALTBalaji have been accused of thriving on hypersexualized content, which critics argue threatens to undermine the creative potential of Indian OTT media. These ongoing legal challenges present a significant hurdle for the platform's long-term future.

Available on both Android and iOS, Kooku offers its subscribers a range of subscription plans, starting at ₹63 for three days, ₹99 per month, ₹162 for six months, and ₹225 for a full year. This affordable pricing has helped it gain significant traction in Tier 2 and Tier 3 cities, becoming a go-to destination for audiences seeking short, punchy, and unfiltered entertainment. The platform is known for its high-volume release schedule, regularly dropping new episodes and series to keep its subscribers engaged.
