We are a mid-size startup running Scala apps. Moving from Jenkins/EC2 to Spinnaker/EKS and looking for a tool to cover our CI/CD needs. Our code lives on GitHub, artifacts in nexus, images in ECR.

Drone is out, GitHub actions are being considered along with Circle CI and GitLab CI.

We primarily need:

• Fast SBT builds (caching)
• Low maintenance overhead (ideally serverless)
• Everything as code
• Ease of use
