WebHarvy Alternative

The Cloud API Alternative to WebHarvy

Move beyond desktop scraping. AlterLab runs in the cloud — no installation, unlimited scale, and full API integration for your data pipelines.

  • Cloud-based — no installation or local compute required
  • API integration — embed in any language or workflow
  • Scales to millions of requests — no desktop limitations

Why Teams Switch from WebHarvy

1

Cloud scale vs desktop limits

Desktop scrapers are limited by your local machine's resources and IP. AlterLab runs in the cloud with managed proxy infrastructure, handling scale that desktop tools physically cannot.

2

API integration vs desktop GUI

AlterLab integrates directly into your code and data pipelines. No need to open a desktop application, manually configure selectors, or export CSV files.

3

Pay-per-request vs license fees

AlterLab charges only for the requests you make. No upfront license fee, no per-seat costs, and no version upgrade charges.
