JSitor, an alternative of CodePen, JSBin and JSFiddle

JSitor is an online free tool for writing, executing and sharing web and NodeJS snippets. It is a non-profitable product without any ads which gives more editor window to write code.

Key Features

NodeJS and Interactive Shell Terminal

JSitor facilitates the NodeJS environment for writing/sharing NodeJS scripts and installs NPM modules. Also its free.

Monaco Editor

JSitor uses Monaco Editor which is developed by Microsoft and also used in VSCode. If we compare this with other alternatives, they are using CodeMirror and CodeMirror has its own stability and usability issues. Monaco editor is more satisfactory and stable editor compared to that.

Take a look at, how beautiful autocomplete looks like in Monaco Editor, isn't it better?

Comparing with CodeMirror autocomplete

Console View

JSitor shows the console logs in the editor itself without having a need of opening the DevTools. This is sometimes very helpful when we want to quickly check the logs without opening the DevTools which takes half of the editor space.

Fullscreen tab view

JSitor gives you a full-screen tab view which gives enough space for writing/viewing huge source codes. Apart from that, it also provides basic views such as side by side view, result in the bottom etc.

Collaboration

JSitor supports collaboration working environment with the help of TogetherJS. This feature is generally really helpful for taking remote interviews or to invite others to work on the same snippet.

Babel, JSX, Script Module and TypeScript

JSitor supports all different type of transpiler, which help us to write code for any framework such as ReactJS, Angular etc

PostCSS, Less, SCSS

JSitor supports all different CSS preprocessors

Pug

JSitor supports Pug HTML formatting as well

Optional Chaining

Nullish Coalescing

All snippets

You can view all your snippets

Trending, Most View and Recent Snippets

You can view some trending, most viewed and recent snippets as well under Trending tab

Embeddable

You can embed the snippets on another blog/articles sites

iOS and Android Apps

JSitor also gives you the benefit of writing/sharing or viewing the code in Mobile app. This is really helpful when we are away from our computer and want to quickly test out something.

Download iOS Application
[Download Android Application (https://play.google.com/store/apps/details?id=com.ashvin777.apps.jsitor) The Android is not yet upgraded, I am working on upgrading the Android app well, you will soon hear some news.

Excellent creation!

You should also create a deployable build and host it so that others can contribute to your code. The biggest disadvantage to most such code playgrounds is that they are all closed source.

This can be different. I think it will be worth it.

Good Luck!

I will cover a feature review of this on my blog.

Thanks Ganguly. I will look forward to any possibilities of making it open source so that we can have a great community to support this tool. I can't promise but I will try. Thanks and keep using JSitor, if you have any feedback please let me know.

Very cool, man!

I rarely use code sandboxes, but when I do I usually go with jsbin. It has some kind of emmet, which is very convenient. And I like overall experience with jsbin.

But I'll definitely keep an eye on JSitor. Full-screen tab view is awesome. Best of luck!

You can't scroll any of the source code panes in Firefox.

Firefox issue is now resolved and JSitor is updated with this fix. Try it out in Firefox now - jsitor.com/3hZCzip7o

If it doesn't work, make sure you clean your cache as it uses Service Worker for caching resource locally which might take some time to load.

I have to say I'm really impressed by the iOS app.
I've tried using CodeSandbox on my iPhone during my morning commute but it was really frustrating, 5 minutes with JSitor and I've already written a small React app with it! The symbols shortcuts on top of the keyboard are on point.
Of course there's room for improvements but it's a pretty good start.

Thanks, Maxime. Yes, the iOS app is very straight forward and easy to use. Also, the good thing is, if you log in and save the snippets, those snippets will be available in the web version as well and vice versa.

Do let me know if you find any issues or any improvements. I will be happy to resolve them. Thanks.

Is there a way to open a GitHub project in your editor? Love the project BTW

Thanks FultonB. Sorry, we do not have that feature, also to support that we will need to support file explorer as this tool is very basic with just HTML, CSS and JS tabs. Thanks for the suggestion, we will look forward if we can support this.

This looks awesome! I am curious about the long term business plan? will it always be free? are you supporting it financially on your own? Will you be community donation driven?

Hi Ahmed. Currently, it not supported by any firm or sponsors. It is an individual contribution to make web developers world better. I don't like to add ads in the web tool just because ads take too much space.

Great work, Ashvin!

I was in search of something like this for conducting interviews after Microsoft discontinued skype interviews. Couldn't find a platform with collab and REPL support for Javascript.

Thanks much!

Welcoming addition to the editors group. The iOS app is truly unique feature. I do wonder do you have support/plans for iPad app?
iPad Pro with jsitor might become way closer to good dev machine on the go

Looks good. Could you add the following

  • Private share
  • Ended code to the website
  • HTML to include Markdown

I am looking for it to store Jekyll code. So support for YAML would be great. Mabe as an additional view

Is there an API where a site can send data, like you can for Codepen? This way you can have examples on a site, then user can click and modify code as needed.
