VS Code Marketplace Extension Scraper

Scrapes VS Code extension listing pages on Visual Studio Marketplace and exports publisher, version, license, repository link, engine compatibility, and marketplace metadata for each extension. Built for developer tooling teams, extension publishers doing competitive research, and anyone tracking the VS Code ecosystem who needs structured data instead of manually checking marketplace pages.

Why this scraper

• Covers the standard fields (installs, ratings, publisher) plus repository URL, license, minimum VS Code engine version, and verified-publisher status — fields most extension scrapers leave out.
• Priced at $0.001 per extension, well under the $0.0025+ typically charged for comparable scrapers.
• Input is just a list of marketplace URLs — no auth, no scrolling, no CAPTCHA handling required on your end.

Note: fields like install_count, rating_average, rating_count, and review_count depend on data being present on the page at scrape time and may return null if the marketplace doesn't expose them for a given extension.

Pricing

$0.001 per extension scraped. A run of 50 extensions costs $0.05; 1,000 extensions costs $1.00.

Use cases

• Tracking install and rating trends for a portfolio of extensions your team publishes.
• Auditing license and repository transparency across extensions before recommending them internally.
• Building a comparison table of competing extensions in a category (e.g., Python linters, Git tools) by engine compatibility and publisher verification status.
