Vumbnail

These docs describe the product and double as its build spec

Vumbnail is a real, running service. Every page is badged with its true status — Live (serving production traffic), Flagged (built but gated off), or Planned (designed here, not built yet). The machine-readable spec a build agent reads lives at /llms-full.txt.

What it is

A thumbnail image host for video. Take any Vimeo or YouTube URL, swap it for a vumbnail.com/<id>.jpg URL, and get the poster frame back as a real JPEG — cacheable, hotlinkable, and globally fast.

How it makes money

Thumbnails are free up to a monthly request allowance. High-volume sites that cross the line are served a watermarked image until they subscribe; paying customers are allow-listed back to clean images automatically.
