There is no free tier. The public pages and the live demo are free for everyone; tracking your own watchlist is paid. History from 5 Sep 2026 is included on every plan.
For one publisher watching their own extensions and a few rivals.
For publishers with a portfolio, or anyone tracking a category closely.
For dev tools companies and agencies. Seats, API and MCP budget.
Extensions are anything on your watchlist, yours or a competitor’s. Both registries count as one extension.
Keywords are tracked per extension on both registries, daily, to position 1,000. Marketplace ranks are the median of three samples.
Competitors are other extensions pinned against one of yours for side by side charts and alerts. They do not count as watchlist extensions.
Refreshes fetch keyword ranks for one extension right now instead of waiting for the nightly run.
