    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.

    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.

    Pros:    Accuracy|User-friendly|Api integration
    Cons:    Speed
