When comparing Drone.io vs Concourse CI, the Slant community recommends Drone.io for most people. In the question“What are the best continuous integration tools?” Drone.io is ranked 11th while Concourse CI is ranked 13th. The most important reason people chose Drone.io is:
Drone.io integrates perfectly with GitHub, BitBucket and Google Code.

Pros
Pro Integrated with GitHub, BitBucket, and Google Code
Drone.io integrates perfectly with GitHub, BitBucket and Google Code.
Pro Easy self-hosted setup
Drone can be easily set up locally: all that's needed is Docker.
Pro Docker integration simplifies deployment
Drone uses Docker containers to build and test code. Using Docker containers makes it easier for developers to then deploy this code to production.
Pro Gitea support
Supports Gitea (Git server).
Pro Local iteration
Debugging on remote build agents is a nightmare (especially without isolated builds). Concourse CI can be run locally. When there are problems with the pipeline definition, it can be run and debugged locally. That means it takes less time to find and fix problems.
Pro Flexible
Resources are to Concourse as plugins are to Jenkins. In other words, resources allow Concourse CI to do just about any work necessary in a build. But resources follow a "service provider interface" that makes them easy to build in any language (not just JVM languages) and have a clearly defined computing model, built for composition. Resources don't clutter UI or tax performance.
Pro Scalable, reproducible deployment
BOSH is an open source tool for release engineering, deployment, lifecycle management, and monitoring of distributed systems. Since Concourse CI is built on top of BOSH, Concourse can scale across many servers or be run in the Cloud.
Pro Isolated builds
Build isolation keeps workers "clean". There's no configuration drift of agents. Or flaky interactions between build jobs.
Pro Usable
Visual pipeline view makes it clear what the automation does. Simple navigation to logs makes it easy to understand what happened in a build.
Pro Simple
Concourse defines three primitives that, together, can express arbitrary features and pipelines.
Cons
Con Does not allow you to configure two projects using the same GitHub repo
Drone.io does not let developers configure two different projects against the same repository. Instead, one must fork that repository into a new one and use that to create a new Drone.io project.
Con Limited infrastructure options
The downside of building on BOSH is that a full, scalable deployment of Concourse CI requires AWS, vSphere, or OpenStack. If you don't already have these, any one of them can be a big effort to set up, just to get a build server running. Might not be a good fit for smaller teams.
