← VS Code Marketplace data

Testing extensions on the VS Code Marketplace

878 extensions from 820 publishers in this category, with real install counts. Part of a free 64,464-extension dataset.

The median Testing extension has 82 installs, against 804 across the whole sample. At least 51.9% of them have fewer than 100 installs. The category holds 1.1% of all installs in the sample.
Read this before quoting anythingThis is not a census and it is head-biased: each category was paged from the most-installed downwards until a cap, so the tail below the cap is missing. Every “under N installs” figure here is therefore a floor, not an estimate — the true share is higher, because everything the crawl did not reach lies below everything it did.

An extension is counted once, in the first category the crawl saw it in, so a multi-category extension does not appear twice in these tables and the category totals do not double-count. That also means this list is not everything the Marketplace would show you under Testing.

All of it, free. One JSONL row per extension, the same data as CSV, the machine-readable summary, the crawler that produced them and the list of rows withheld because their publisher id has the shape of a credential. CC BY 4.0, DOI-archived, no signup and no email. extensions.jsonl extensions.csv the repository
