Compared a few options
Evaluated this against two competitors. Where it wins: official SDKs for Python, Node.js, C#, and more and fast response times suitable for automation. On balance the feature set — especially support for reCAPTCHA, hCaptcha, and image CAPTCHAs — justifies the 5 stars for our use case.
Years in this space
I've evaluated a lot of these over the years. What stands out here is dashboard for monitoring usage and balance — handled better than most — and supports many popular CAPTCHA types. Worth the time if this is your use case.

Use it every day
Honestly didn't expect to like it this much. Machine learning-based recognition engine is exactly what I needed, and competitive pricing per solve. but I reach for it almost every day now and it just clicks.
