How to choose

Which detection signals does it need?

Choose based on the signals that match your risk. Behavioral analysis looks at activity patterns, while device fingerprinting helps recognize a returning device. Check for protected-request controls, challenge tools and account-abuse detection when those matter to your service.

A JavaScript SDK can add checks to a website, and a real-time scoring API can return a decision while a request is in progress.

Which platforms does it need to run on?

Check support for web, API, Android, iOS, Windows or self-hosted deployment before choosing. Platform availability varies by tool, so match the product to the places where users sign in or send requests.

What will bot detection cost?

Start with a free plan when you need to evaluate a service without a subscription. Anubis and BotD list free plans; Castle lists a free plan with paid service from $200 per month.

Paid examples include Fingerprint from $99 per month and hCaptcha Bot Detection from $99 per month on annual billing. Alibaba Cloud Anti-Bot Service starts at $1,150 per month and lists a seven-day trial.

Can I try it before paying?

Trial terms differ. Fingerprint and hCaptcha Bot Detection list 14-day trials, while Cloudbric and Radware Bot Manager list 30-day trials. Alibaba Cloud Anti-Bot Service lists a seven-day trial; StyloBot lists a 30-day trial.

Does it need a public API or open-source code?

Use the board marks to check for a public API and open-source status. A public API can connect scoring to an existing service, while open-source code lets you inspect and manage the implementation; review the licence before choosing.
