DroneCI

Self-service continuous integration and delivery platform built on container technology. Pipelines run as declarative YAML in the repository, with each step executing in an isolated Docker container that is pulled at runtime, keeping builds reproducible and environment setup to a minimum.

Acquired by Harness while staying open source via a Community Edition. Differentiates from Jenkins and legacy CI by using Docker as the build primitive: no agent configuration or host dependencies, just container images. Supports GitHub, GitLab, Bitbucket, Gitea, and Gitee, and runs on Linux, ARM, ARM64, and Windows.

Key capabilities:

• Configuration as code with pipeline YAML committed to the repository
• Docker-based steps and services for any language or toolchain
• Plugin ecosystem using containers for deployments, notifications, and artifact publishing
• Single binary install with automatic scaling
• Native multi-architecture and multi-SCM support

Teams use Drone to automate build, test, and release workflows without managing build servers. Integrates with source control webhooks for push-triggered pipelines and fits into GitOps-style deployments. Works well for polyglot projects where each service can specify its own build container.
