Mockend
Mockend creates mock REST and GraphQL APIs from a file in a repository.
About Mockend
Mockend is a GitHub App that generates a hosted fake REST and GraphQL API from a mockend.yml configuration file in a GitHub repository. The file defines models, generated or user-supplied sample data, and relations between models. Once the file is committed, the API is available at mockend.com/api/{owner}/{repo}, and the homepage states that no server needs to be run or installed.
The service is intended for frontend work, prototypes, documentation and demos. Writes are accepted but not saved, so each use starts from the same dataset. The homepage describes a 14-day free trial, with billing handled through GitHub. Pricing is listed as trial in this directory entry.

Mockend FAQ
Do I need to run a server to use Mockend?
No. According to the homepage, you add a mockend.yml file to a GitHub repository and the API is hosted for you.
How can I keep a Mockend API private?
You can set a key in the config file. The homepage says this keeps the API hidden from the rest of the internet. The key is optional.
Does Mockend read the code in my repository?
The homepage states that Mockend only reads the config file and never your code.
