ReadMe Build vs Sandbox: What are the differences?
What is ReadMe Build? Build, deploy and share APIs & microservices easily. Build allows you to really easily move from code to deployed services without ever having to worry about provisioning, setting up and managing servers. You focus on code, we handle the rest - simple.
What is Sandbox? Quick and easy mock RESTful API and SOAP webservices. Quickly mock RESTful API or SOAP web-services with simple or dynamic responses, and fault injection to simulate real application behaviour.
ReadMe Build and Sandbox can be primarily classified as "API" tools.
Sandbox is an open source tool with 161 GitHub stars and 28 GitHub forks. Here's a link to Sandbox's open source repository on GitHub.
