VS Code Marketplace Scraper

Get VS Code extension data with the numbers publishers actually care about, no login or API key. Search extensions, pull a publisher's whole catalog, or list a category, and every extension comes back as one clean row with install count, downloads, average rating, rating count, and daily, weekly and monthly trending scores.

What it does

• Search, publisher, or category - query by term, pull everything from a publisher, or list a category.
• Install counts and trending scores - the adoption and momentum numbers, not just a description.
• Ratings - average rating, weighted rating and rating count.
• Top listings - leave the inputs empty to get the top extensions by your chosen sort.
• Pagination - walks 100 at a time up to your limit.

Common uses: extension market research, competitor and category tracking, finding trending tools, and monitoring your own extension's adoption over time.

Extensions with no ratings yet return null for the rating fields, so the shape is always the same.

Notes

• No login and no API key. Set a search term, publisher, or category and run.
• Trending scores are the momentum signal; schedule the run to build a time series.
• maxItemsPerSource goes up to 10000 per source for full category sweeps.
