User reviews
Cowin Booking Chrome extension is praised for significantly simplifying and speeding up the process of securing COVID-19 vaccination slots, with many users booking within minutes. Its automated form filling and captcha handling are major advantages. However, recent restrictions on the CoWIN portal have caused issues like session termination after multiple refreshes and booking failures. Users also report occasional functional glitches such as incorrect location selection and frequent logouts. Despite these challenges, users appreciate the developer's efforts and the extension's overall effectiveness.
Pros
- Effectively helps users book COVID-19 vaccination slots faster and with less hassle.
- Includes captcha handling, making the booking process seamless.
- Saves users significant time by automating form filling and slot searching.
- Provided for free and appreciated by many users worldwide.
- Useful especially in regions with high demand and difficult offline booking.
Cons
- Recent CoWIN portal updates introduced refresh restrictions causing booking failures.
- Some users experience repeated logouts or 'something went wrong' errors after captcha confirmation.
- Extension sometimes does not correctly select state or district details.
- High refresh rates cause rate limiting, requiring users to increase refresh intervals.
- Users seek clearer guidelines on ideal settings for refresh timing and login preparation.

Ramesh Mahalik, 2021-06-09Thank you brother,
You have done a great job.
I have a request, before when there was no refresh restriction I set refresh value in 2 seconds and I booked my slot. But now I am booking it’s just log out again and again, due to only 20 refresh restriction. And I am unable to book. when I set it refresh time to 10 to 15 seconds. it shows me fully booked.
Can you do something like it search and booked without refresh or something internal refresh.
Please find out a way to resolve this issue.
Thank you once again brother.
