Chrome Web Store
My own browser extensions
I designed and built eight Chrome extensions, and took all eight through the Chrome Web Store review myself.
The question
People who build or research websites often want one quick answer about the page in front of them. What structured data it declares, which AI crawlers it allows, which companies it talks to. I wanted a small extension for each question that answers it in one click.
See it live: murmtools.comWhat I built
- MurmSchema shows what structured data a page declares, and which blocks a parser would reject.
- MurmCrawl reads robots.txt and the meta tags and tells you which AI crawlers a site allows or refuses.
- MurmStack counts how many separate companies a page contacts, and shows what the site is built with.
- MurmSpy and MurmAds: research on Shopify stores and in the Meta Ad Library, with no account.
- MurmProof, MurmPulse and MurmMargin: affiliate links and their disclosure, whether a product is still climbing, and the real landed cost of a supplier listing.
Where it stands
- All eight are published in the Chrome Web Store, after Google's review.
