From python script to chrome extension in 4 hours

i had a working SEO scanner on my linux server. python, requests, beautifulsoup. scans any URL, checks 10 things, scores out of 100.

problem: nobody uses it because they have to hit my API. thats friction.

so i rebuilt the whole thing as a chrome extension.

what changed

server: paste URL, wait for API, get JSON.
extension: click icon on any page, instant popup. zero friction.

scanner checks title tags, meta descriptions, alt text, heading hierarchy, structured data, canonical URLs, viewport, page speed.

the build

python to javascript. content scripts inject into page DOM. vanilla JS only. manifest v3 was annoying.

free vs pro

free: score + top 5 issues.
pro ($9/mo): full issue list, fix suggestions, CSV export.

chrome extensions have built-in distribution. the store IS the channel.

anyone built a chrome extension product? what were your install numbers month 1?
