Want to book vaccine slot easily? Try Co-WIN Booking Google Chrome extension

Indian government earlier in the year in January launched the world's largest vaccination drive to combat the Covid-19 pandemic.

However, from day one, the programme has been constrained with glitches with regard to booking the vaccine slot on the state-run Co-WIN website. So far, 20 crore people have been vaccinated out of 138 crore population.

Several crores of people young and old have tried logging in to the Co-WIN website for several hours to book the slot, but not able to find one. Those working from home are finding it tough can't focus on work and also keep checking Co-WIN website refreshing the page.

In a bid to help more people get the vaccine, several technology companies such as Paytm, Jio, Airtel, among other introduced tools in their respective mobile apps to find the nearest vaccine centres. Also, several groups of well-intentioned techies launched bots on Telegram, WhatsApp, and other messenger apps to deliver similar services.

Now, a freelance developer Sushrut Kasture has come up with a novel Chrome extension- 'Cowin Booking', which greatly reduces the workload.

Once you fill the pop-up auto-fill application form, it will automatically book the vaccine slot in the nearest public health centre.

Kasture also notes that personal information (phone number) asked during registration is completely safe. All information typed in the auto-fill application will not be saved nor sold to any third-party clients.

"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's on his GitHub account.

" The extension (Cowin Booking) does not collect or store user's 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 autofilling the possible inputs and simulating clicks automatically on different buttons," reads the Terms of Use page of the Cowin Booking Github website.
