App Store Optimization radar: real keyword popularity and rankings, tracked over time, queryable by an LLM.
A self-hosted backend that reads the keyword popularity index and the ranking data the app stores only expose to their advertisers, snapshots them into a database, and keeps the history — so a release can be measured against what moved. The scraping runs on kdriver and the fetch queue on kourier.
It ships an MCP server alongside the REST API, so the tracked keywords, the app ratings and the suggestions can be asked for directly from an LLM. It is how I do the ASO of my own apps.
