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

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.
Looks good. Could you add the following

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!
Thank Robin for your feedback.

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
Hi tpaktop,
Thanks for your interest. The iOS app is also supported on iPad devices.
How is it different from codesandbox?
Hi Pavel, Codesanbox is more of full IDE where one can create multiple files, mostly helpful for creating/testing big projects. It's a great tool. Whereas JSitor is just a tool to quickly test/create your small snippets instead of having a need of full IDE.
Try playcode.io - it has emmet.
Hello π
playcode.io - used Monaco editor too.
The online JavaScript editor support multi files and fast view as you type β‘οΈ
Itβs my product and you should try it π
PlayCode.io is awesome π
Thank you Ashvin π
