Crestle (https://www.crestle.com/): + super quick to setup + free trial no CC required o underlying GPUs are ok - more expensive than others

Google Colab (https://colab.research.google.com/): + Free + Works as a plugin within Google Drive - Very limited hardware - Integration with data storage could be easier

I'm going to try Gradient as well. Paperspace has very competitive pricing and their new service seems to hit the nail in terms of ease of use vs control of settings. Any chance @dkobran has a coupon code to take it for a spin? :)
