You've seen shields.io badges for build status and stars. Pulse gives you the same flat SVG badge for a live view (or like, or comment) count on any public post — a YouTube video, a Hacker News thread, a Stack Overflow question — as a single image URL that updates itself. No badge-hosting service, no token, no refresh job.

Renders, live:
Give /badge any post URL and it shows the most meaningful number that
platform exposes — views where available, else likes, else comments.
Add ?metric= (views, likes, or comments):

A Hacker News thread (points), a Stack Overflow question (views):
Pass a profile URL instead and you get a follower badge — see the follower-count badge guide.

—
color takes blue, green, gray, red,
purple, or a hex value.
Badges send a 1-hour Cache-Control, so GitHub's image CDN refreshes them
without hammering the API — the number stays current within the hour, which is plenty for a README.
No signup, no key. For commercial use or volume, Pro is $19/mo — see pricing. Full /badge docs.
