Free development environment in the browser. What are the options?

Question

IDE

Good day friends!
A few years ago I learned to write in nodejs. I did experiments on cloud9 , this is a browser IDE.
Very convenient, a good development environment appears in the browser, it was possible to write code anywhere, on anything. From my working computer, everything didn’t always work out well for me, because I had to install firewood, then configure the server.
And here everything is always set up, just select the project under the node, update it, install the necessary libraries and go ahead.
And now I want to make a telegram bot, I opened this site, and it says that it no longer works. Like, go to AWS.
Then, I found an alternative, codeanywhere. It was very simple to deploy the project under the node, as a result it turned out that in the free version, I can only work for 2 hours!
Carl 2 hours)))
I think that there should be more such services, and for such beginners who want to learn, there should be accessibility.
Please share, what are the services that provide free cloud development services, right in the browser?
