Overview
Drone CI is an open-source, container-native continuous integration and delivery platform where every pipeline step runs as an isolated Docker container, configured through a declarative YAML file checked into the source repository.
Originally created as an independent open-source project, Drone is now maintained as Harness CI Community Edition following Harness's 2020 acquisition of Drone.io, with Harness offering a separate commercial enterprise CI/CD product built on the same foundation.
Key Features
Every pipeline step executes inside its own Docker container, giving teams full control over the runtime environment for builds, tests, and deployments without dependency conflicts between steps.
Pipelines are defined in a `.drone.yml` file for git-versioned, infrastructure-as-code configuration, and Drone's plugin ecosystem lets teams reuse hundreds of community-built container plugins for common tasks like deploying to cloud providers, pushing container images, or sending notifications.
Pricing
Drone CI's core Community Edition is fully open source and free to self-host on a team's own infrastructure, with no licensing cost.
Organizations needing managed hosting, dedicated support, or advanced enterprise security and compliance features can upgrade to Harness's commercial CI/CD platform, which is sold at custom, quote-based pricing rather than published self-serve rates.
Key Features
Container-native pipeline steps — Every build step runs inside its own Docker container, giving isolated and reproducible execution environments.
Declarative YAML pipelines — Pipelines are defined in a version-controlled .drone.yml file, following an infrastructure-as-code approach.
Extensive plugin ecosystem — Hundreds of community-built Drone plugins, themselves Docker containers, handle deployment, notifications, and registry pushes.
Language-agnostic builds — Since any Docker image can be used, Drone can build and test projects in virtually any programming language or framework.
Self-hosted deployment — Runs entirely on a team's own servers or Kubernetes cluster, giving full control over infrastructure and data.
Horizontally scalable runners — Build execution can be scaled out across multiple runner nodes to handle larger or parallel build workloads.
Git-triggered automation — Pipelines automatically trigger on git events such as pushes and pull requests from popular source control providers.
Open-source community edition — The core platform is free and open source, maintained as Harness CI Community Edition after Harness's acquisition of Drone.io.
Pros & Cons
Pros
Genuinely free and open-source core product with no forced feature paywall
Container-native design gives strong isolation and reproducibility for every pipeline step

Backed by Harness, giving the project ongoing maintenance and enterprise upgrade path
Cons
Requires self-hosting and Docker/Kubernetes knowledge, unlike fully managed CI services
Enterprise features and support require moving to Harness's separate commercial product
Smaller active community and slower feature velocity compared to GitHub Actions or GitLab CI
Documentation for the community edition is less extensive than for Harness's commercial CI offering
