generates super-fast custom placeholder images.

About generates custom placeholder images on the fly. All of these images are generated on Cloudflare's Edge at 200+ locations, ensuring the best possible performance for all of end-users. All images are cached for lengthy periods of time.

Placeholder images can be useful for prototyping application design, blog posts, themes and other templates before publishing to production.
