I like that it is easy to use for both front-end developers as well backend/data engineers, also has great documentation! It's not free but you can try their demo account first before purchasing anything with your credit card or PayPal info (or any other payment method). Some of our applications are quite large in size so we needed something scalable which could handle millions upon million requests per day without breaking down - this was solved by Protoforce API platform & service offering us amazing scalability at an affordable price point compared against competitors offerings from AWS etcetera where they charge way more than what Protoforce charges!! We've been using protos force since early 2018 till date now i would say its one best tool out there when comes scaling problems especially if need some help solving issues related around code deployment such infrastructure provisioning services orchestration.
