THE DECISION
Analyze a competitor beyond today's store page.
Extension Lookup connects an extension's current profile with every change we detected before it, so one interesting move becomes the start of a real investigation.
WHAT CHANGED
Which listing or release fields changed?
Follow version, title, description, and Featured-status changes we detected with the date range for each.
GROWTH CONTEXT
What happened around the change?
Compare growth in the 30 days before and after a change to judge whether it deserves deeper research.

THE EVIDENCE
Every listing, tracked over time.
350K+ extensions indexed with their current metadata, historical series, and the changes we detected in between, giving you the context a single store page can't show.
CURRENT PROFILE
Current extension profile
Users, rating, reviews, version, badges, locales, last store update, and other indexed store fields.
TIME SERIES
Growth and reputation history
Collected user, rating, and review history shows the direction an extension is moving.
DETECTED CHANGES
Listing and version changes
Adjacent crawls reveal changes to version, title, description, and Featured status.
CONTEXT WINDOW
Growth around a change
Where coverage allows, compare the 30 days before and after a change instead of judging one point alone.
WHAT THIS CAN'T TELL YOU
Change dates are detection windows, not edit timestamps.
- History comes from periodic crawls of public store data. We show the interval in which a change was detected, not the exact minute it was made.
- Growth around a change is context for your investigation. It is not proof that the change caused it.
PRODUCT QUESTIONS
Straight answers before you commit.
Does “not indexed” mean the extension does not exist?
No. It only means the extension is not yet in our database of 350K+ indexed extensions.
Which historical changes can I inspect?
Where snapshots support them, the profile can surface version, title, description, and Featured-status changes alongside users, ratings, and reviews.
Are the change dates exact?
Not always. A change is detected between crawler observations, so the product presents the observation interval instead of inventing an exact edit time.
Can I inspect an extension I do not own?
Yes. You can inspect any extension in our database without proving ownership.
