I already clone a sample RAML for test in ( my credential’s ) Anypoint studio and able to run and test in mock test.

Question : Any other ways or tools perhaps to deploy the API online ? without any difficulties of setting up proxy gateway etc ?

Reason: my laptop is slow and mulestudio run very slow on it.




If I understood the question correctly, you want to run and test your API in online tool without much configuration and setup.
If that is the case, you can try API designer which is a cloud based online tool to design your API using RAML and test it there instantly without much difficulties.
You can also setup proxy APIs there with API data gateway for your APIs.
