PageSieve door Julius K

PageSieve is a browser extension that assists with the extraction of structured data from any webpage you visit. Define field names, CSS selectors and (optionally) pagination strategy then extract and export data in your desired format (JSON, YAML, CSV etc).

When you need to crawl a large number of pages, use the CLI (available on npmjs) to run the same scraping workflow through a Headless Browser or Plain HTTP using the reusable recipes.

The extension is designed around a few core principles:

• Ergonomic CSS selection - discovering CSS selectors should be a simple point-and-click operation.
• Minimal UI - in-browser sidebar that does not take you to a different application.
• Local first - scraping can be done entirely on device.
• Reusable recipes - once you define fields and selectors, you can save your
  configuration for use at a later date or share it online.

Some key features include:

• Point-and-click selection: Easily discover CSS selectors for any element.
• Minimal Sidebar UI: No need to leave your current tab. Define how and what to extract data in one UI.
• Reusable Recipes: Import / export configurations as reusable recipes (plain JSON files)
• Local-first: All extraction is performed entirely on your device.
• Run in Headless Browser: Use CLI to run the same configuration using Playwright or Plain HTTP.
