I have always wondered how web-based javascript prototyping tools like jsbin, work. So, I made one, then I put more stuff in it, because I wanted something between codepen and . Playground features:

Current

Phosphor desktop-like, themable UI with resizable and draggable panels Multiple javascript panels per sketch - break up your experiment into multiple pieces use libraries via require() or script tags Multiple CSS panels per sketch Runkit Endpoint panel for scripting runkit-hosted endpoints Runkit runner panel as a server-side scratch pad Saves state to localstorage

Planned

virtual file system. Mount your data sources as file systems Supports all the latest JS bells and whistles with dynamic Babel transpiling Fully decentralized data storage - store your worspaces on the decentralized web Publish sketch to IPFS - publish your entire sketch to IPFS for fully decentralized hosting and delivery Social sharing - follow other users,
