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
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.
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.
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.
