Never lose your work

Losing work sucks. We know that and we've felt it. That's why we made it almost impossible to lose yours. We keep track of your most recent work and keep a copy of all of your unsaved code. Every time you start an experiment, open a Plunk, a Gist or a Githubrepo, we save that for you and let you catch up where you left off.

Desktop integration

Plunker isn't a one-way street. Drag files from your desktop into the Plunker Editor's file tree and let your imagination go wild. Images? Sure. Animated gifs? Why not? This goes both ways. When you're ready to graduate, drag your project right to your desktop in one pretty little zip file ready for upload!

Site-wide search

Wouldn't it be great if you could find exactly what you were looking for? That example that unblocks you and reveals that one insight that was missing. That's what search is all about. Every project on Plunker is indexed and searchable. Cmd-Shift-F What are you looking for today?

Embeddable editor

All the power of the editor, in a clean little box with a bunch of knobs and levers to best suit your needs. Better yet, if your web-fu is up to the task, your site can generate a dynamic Plunker project on the fly and seed the embedded editor with that.

Real-time preview

Seeing is believing. When it takes a fraction of a second to see the outcome of a change, you can get things done. Fix bugs, tweak the styles and let your consciousness fuse with your tools. The Plunker real-time preview is not magic. What you see on Plunker is what you would get if your code was served directly from a CDN. Actually, that is exactly what is happening for real-time previews. No hiding the boilerplate; when you really want to know what works and why, Plunker is the tool for you.

Multi-file, multi-pane editor

Do you really just want three files when you're building a website? If only things were as simple as that. Plunker understands your reality and gives you a full file tree. Drop your images right into the tree. This isn't your Grandpa's toy fiddle but don't let that stop you from having fun. And what if you have some lingering nostalgia for the good 'ol html, css, js, preview look? No problem! Just drag files into the workbench and rearrange or resize your panes to your heart's content.
