    High Success Rate, Exceptional Support

    I use Capsolver to solve mainly recaptcha v2 and v3 via API. It helps me to bypass those captcha with a good success rate. It's a cheap service with very good documentation for API service, and the staff is very helpful and friendly. Capsolver solves recaptcha v2 pretty fast and with an extremely high success rate. When I've had problems with v3, they have helped me out to increase the success rate.

    Best working Capcha solver!

    I've been using CapSolver for a while now, and it has been a game-changer when it comes to dealing with those annoying captchas. This addon simplifies the whole process and saves me a ton of time. It's incredibly reliable and efficient, making it a must-have tool for anyone who encounters captchas regularly. I appreciate the convenience it brings to my online activities, and I highly recommend CapSolver to anyone looking for a dependable captcha-solving solution.

    ๐Ÿ‘ Pros:    Fast|Active live support|Very reliable|Best captcha solver available
  3. I recently tried out Capsolver in my app, and I'm fairly impressed with its accuracy. There are some issues regarding speed, where if you try to send multiple requests at the same time (with threading), it can take a really long time (4 requests all at once took upwards of 45 seconds), but that's solved using proxies. It was also extremely easy to integrate it into my program, and the API is really user-friendly.

    ๐Ÿ‘ Pros:    Accuracy|User-friendly|Api integration
    ๐Ÿ‘Ž Cons:    Speed
