**c**ompletely **r**idiculous **API** (crAPI) will help you to understand the ten most critical API security risks. crAPI is [vulnerable]( “vulnerable” ) by design, but you’ll be able to safely run it to educate/train yourself.
crAPI is modern, built on top of a microservices architecture. When time has come to buy your first car, [sign]( “sign” ) up for an account and start your journey. To know more about crAPI, please check [crAPI’s overview]( “crAPI’s overview” ).
## QuickStart Guide
### Docker
You’ll need to have Docker installed and running on your host system.
#### Using prebuilt images
You can use prebuilt images generated by our CI workflow.
* To use the latest stable version.
* Linux Machine
curl -o docker-compose.yml https://raw.githubusercontent.com/OWASP/crAPI/main/deploy/docker/docker-compose.yml
docker-compose pull
docker-compose -f docker-compose.yml –compatibility up -d
* Windows Machine
curl.exe -o docker-compose.yml https://raw.githubusercontent.com/OWASP/crAPI/main/deploy/docker/docker-compose.yml
docker-compose pull
docker-compose -f docker-compose.yml –compatibility up -d
* To use the latest development version
* Linux Machine
curl -o docker-compose.yml https://raw.githubusercontent.com/OWASP/crAPI/develop/deploy/docker/docker-compose.yml
VERSION=develop docker-compose pull

**Note**: All [emails]( “emails” ) are sent to mailhog service by default and can be checked on You can change the smtp configuration if required however all emails with domain **example.com** will still go to mailhog.
### Vagrant
This option allows you to run crAPI within a virtual machine, thus isolated from your system. You’ll need to have [Vagrant]( “Vagrant” ) and, for example [VirtualBox]( “VirtualBox” ) installed.
1. Clone crAPI repository
$ git clone [REPOSITORY-URL]
2. Start crAPI Virtual Machine
$ cd deploy/vagrant && vagrant up
3. Visit
**Note**: All emails are sent to mailhog service and can be checked on
Once you’re done playing with crAPI, you can remove it completely from your system running the following command from the repository root directory
$ cd deploy/vagrant && vagrant destroy
