BlurHash vs Holder.js

BlurHash — BlurHash is an algorithm that creates a hash representation of an image which allows previewing that image as it loads, while using very little bandwidth. The hash is typically around 20-30 characters

Holder.js — Holder.js is an open source JavaScript library that generates placeholder images of any size. It can be useful for mocking up website designs before images are available.

BlurHash offers Generates a short hash string to represent an image, Allows previewing and blurring images before they are fully loaded, Works with very small amounts of data - hashes are usually 20-30 characters, Encodes color and geometric information about an image, Open source algorithm released by Wolt under MIT license, while Holder.js provides Generates placeholder images of any size, Customizable background color, Customizable foreground text, Text size and font customization, Rounded corners.

BlurHash stands out for Dramatically improves perceived performance of loading images, Creates placeholder previews using very little data, Lightweight and fast to generate hashes on the server; Holder.js is known for Lightweight, Easy to implement, Open source.
