The Flexible Alternative to ZenRows

Flexible pay-as-you-go

Top up your balance when you need it. No monthly subscription means no wasted credits during quiet periods.

Automatic tier escalation

AlterLab detects site protection and automatically uses the right combination of proxies, browser rendering, and CAPTCHA solving. No manual configuration.

Structured data extraction

Beyond raw HTML, AlterLab can extract structured data using CSS selectors or AI-powered extraction — built into the same API.
