As answered by people managing JSFiddle and ShotLab.

Shotlab focuses on speed and simplicity. Instead of complex design tools, it lets you turn plain screenshots into polished, scroll-stopping visuals in seconds with pre-sized canvases, clean backgrounds, and minimal editing effort.

Most tools are either too complicated or too slow. Shotlab is built for instant results - upload, customize, export. No design skills required.

ShotLab's answer:
Shotlab started as a small side project to solve a simple problem - making screenshots look good without using heavy design tools. What began as a quick experiment turned into a focused product aimed at helping people create better visuals faster.

Test your javascript, CSS, HTML or coffeescript online with jsfiddle code editor. Jsfiddle – code playground.
JSFiddle cannot be used to host code on your server. The code has to be on JSFiddle and is public all the time.
What is missing from JSFiddle is live previews. You have to basically refresh the page by clicking on the play button. And compared to other playgrounds, JSFiddle is probably the slowest. Another slightly frustrating...
I had a good experience using Shotlab. It makes my screenshots look good on my social media and blogs. Would definitely use again when needed, and will also recommend it to my friends.
