In January, the Indian government launched the world's largest vaccination campaign to combat the Covid-19 pandemic. From day one the programme has been constrained with glitches with regard to booking the vaccine slot on the state-run Co-WIN website. Out of 138 crore people, 20 crore have been vaccinated so far.

Several hours to book a slot on the Co-Win websites, but I was not able to find one. Those who work from home are finding it difficult to concentrate on their work while also checking the Co-WIN website and refreshing the page. Several technology companies, including Paytm, Jio, and Airtel, among others, have introduced tools in their respective mobile apps to help people find the nearest vaccine centres in an effort to help more people get the vaccine. Several groups of well-intentioned techies have also launched bots to provide similar services on Telegram, WhatsApp, and other messenger apps.

Sushrut Kasture, a freelance developer, has created a novel Chrome extension called 'Cowin Booking,' which greatly reduces the workload. Once you fill in the pop-up auto-fill application form, it will automatically book the vaccine slot in the nearest public health centre.

Kasture also points out that any personal information (such as a phone number) collected during registration is completely secure. All data entered in the auto-fill application will not be saved or sold to any third parties.

"This extension (Cowin Booking) is not for commercial use. A lot of similar scripts are run by programmers to ensure quick slot booking. To avoid this privilege bias, I have developed this easy, user-friendly extension, "said Sushrut Kasture on his GitHub account.

"The extension (Cowin Booking) does not collect or store users' personal information in any form. As the extension is OSS (Open Source Software), this fact can be verified. The extension (Cowin Booking) does not directly use any of the Co-WIN APIs. It just speeds up the vaccine slot booking process by auto-filling the possible inputs and simulating clicks automatically on different buttons, "reads the Terms of Use page of the Cowin Booking Github website.
