Is Code Sandbox a legit and safe editor?

It's legitimate. In fact, many projects host their own examples on CodeSandbox. If you go to one of the component pages for Material-UI, you'll see above every example there's a pencil icon. Click that, and it will take you to a CodeSandbox that includes the example. For instance, here's the sandbox for the first example on that page I linked: https://codesandbox.io/s/mnvxm That said, it's an online in-browser editor. That's both its up-side and down-side. It's "safe" (not really sure exactly what would be unsafe about it in this context), and it's easier to just get started because they have project templates, but not that much easier. It's easier to share running examples. But at the same time, you're limited to one window in a browser, where in a local editor you can open several files. You also have more control locally. So, it's fine for learning purposes, but you eventually want to start using your own local setup anyway. More on reddit.com

I've started programming, need a Cloud IDE (codesandbox?)

This sounds like you need git. You can make all the changes you want on say, your personal PC. Once done (or need to move to work pc) you can push ("copy") your code from your local pc to a code-hosting-server (e.g. Github, Gitlab, etc) and then just clone ("copy-paste") it onto your work PC and continue there? This is in-line with what the industry uses. I know that Github has an online VS Code available, so you could look into that as well. More on reddit.com

Using CodeSandBox instead of local for projects

What do you mean “using local”? I think you’ve covered the big pros and cons of using something like CodeSandBox. It really depends on what use case you have. I try to do things in a simple way using less dependencies, so I’d always prefer just using syntax highlighting rather than relying on an online service. More on reddit.com

r/learnprogramming on Reddit: Is Code Sandbox a legit and safe editor?

December 8, 2020 -

I am a student and I'm currently learning React JS and my friend recommended this Code Sandbox to use it as a simpler and faster alternative to creating the npm apps on my local machine that React JS usually requires. I just want to ask if that site is sketchy or safe and if it has any drawbacks?

It's legitimate. In fact, many projects host their own examples on CodeSandbox. If you go to one of the component pages for Material-UI, you'll see above every example there's a pencil icon.

r/learnprogramming on Reddit: I've started programming, need a Cloud IDE (codesandbox?)

May 7, 2025 -

I started a programming course to learn HTML, CSS, Javascript and some libraries and frameworks to learn both backend and frontend (tailwind, bootstrap, node.js, next.js, express.js, react and vue.js) there are many exercises/mini projects to do to consolidate the theory and working full time, I find it difficult to use vs code because I use two different PCs (one at work and one at home). I ASK if there is any online IDE that I can use to learn html css and web programming always using the same version of the files because I'm finding it difficult to learn and every time having to transport the code from one PC to another using google drive... I read about: https://codesandbox.io/ https://codepen.io/

But I don't want to buy courses I just want to have an IDE in the cloud to program and therefore always work on the latest version, without having to move folders, jpg, etc of my files (html, css, js, assets etc) every time

What do you recommend? thanks

This sounds like you need git. You can make all the changes you want on say, your personal PC. Once done (or need to move to work pc) you can push ("copy") your code from your local pc to a code-hosting-server (e.g. Github, Gitlab, etc) and then just clone ("copy-paste") it onto your work PC and continue there? This is in-line with what the industry uses. I know that Github has an online VS Code available, so you could look into that as well.

It sounds like the big thing that’s probably weighing you down is your storage solution for your code, not your IDE. You should create a GitHub Account and begin getting comfortable with Git instead of using google drive to store your work, because it’s what you’d use in the real world and it’s far more powerful and tailored for programming. It takes a second to get a handle on, but it’s worth it.

r/reactjs on Reddit: Using CodeSandBox instead of local for projects

April 9, 2024 -

Is there any other reason for using local over codesandbox-type online editors, than the fact that it gives local hosting and is with the files locally secured? Thanks in advance.

What do you mean “using local”? I think you’ve covered the big pros and cons of using something like CodeSandBox. It really depends on what use case you have. I try to do things in a simple way using less dependencies, so I’d always prefer just using syntax highlighting rather than relying on an online service.

Pricing model aside (I'm not sure what the pro plan for CSB looks like these days) you're going to have a development environment that is much weaker than a MacBook Pro. That may be significant for you if you're doing ETL on large data sets, or training AI models, or other heavy computational tasks. CSB is probably fine if all you're doing is rendering a web app though. I believe CSB supports Docker now, so you can have a devbox with your full backend services included, but there may still be restrictions depending on if you're free tier vs paid.

How to run an application in codesandbox with different subfolder for backend and frontend

You can't do that on codesandbox without Express as far as I know, here's a relevant Github issue: https://github.com/codesandbox/codesandbox-client/issues/1519.

This is for now not really possible unless you just display an HTML page from express :(

I took the express example starter template and edited it to work with 2 separate folders like your requirement, here's the link: https://codesandbox.io/s/cool-worker-wj464?file=/backend/app.js

I just created and renamed a folder and changed the code to use the right directories.
