Test Companion
Verified publisherWhat a VS Code verified publisher badge means, compared with Open VSX →
AI-powered Testing, right inside your IDE.
Tracked since 5 Sept 2026
Daily readings on both stores, taken by us. As of 25 Sept 2026.
Each bar is one day’s change in the store’s own counter. Open VSX counts a download on every update, so a day includes updates by people who already had it. Days before 5 Sept are reconstructed from public archives rather than read by us.
Where Test Companion ranks in search
Positions observed daily on both stores. Neither store publishes this, and the two run separate search engines over separate catalogues.
#12 on Open VSX for “testing”, nowhere on Marketplace.
