is there any online ide to test my custom scripts for frappe framework?

I have been customizing Erpnext v 14 OVA and run it on a Desktop with a good performance but for some reason it stops working all of a sudden and will be back by itself after 5 minutes or so by itself i couldn’t get any error messages when i check the database its active and running, so what could be the problem can anyone tell me how to curb this issue and if anyone got this type off issue on this specific version.

note:- i have increased the buffer size and all
