LionSpider - Web Data Scraper

LionSpider – Lightweight Web Data Scraper, a visual web crawler browser extension.
No coding is required: with point‑and‑click configuration you can perform web scraping and web data collection directly in the browser.
If a page is accessible in the browser, LionSpider can capture its data, while naturally inheriting the browser’s behavior and anti‑bot characteristics.

In today’s era of information explosion, the ability to acquire and process data has become a core competitiveness for both individuals and organizations.
