Why teams choose ZeroBot over Kasada
Minutes to integrate, not weeks
Kasada requires engineering work to wire up. ZeroBot runs on a single API call or a plugin install.
Humans barely notice us
Kasada's JS proof-of-work heats up CPUs on older phones. ZeroBot's soft-challenge appears only on suspicious traffic and uses a light slider — most visitors never see a challenge at all.
No annual floor
Kasada is an annual contract conversation. ZeroBot is billed monthly and cancellable any time.
Built-in infrastructure
Kasada is bot scoring only. You still need a hosting provider, a WAF, captcha, and a log pipeline. ZeroBot bundles all of that.
Real dashboard access from day one
Kasada onboarding involves a solution architect and an implementation timeline. ZeroBot: register, paste license, done.
Verdict: Kasada is a specialist tool for defending ticket drops and sneaker bots. For everything else — fraud, scraping, login abuse, account takeover on normal web apps — ZeroBot delivers the same protections at a fraction of the integration effort and cost.
