CDF Welcomes Its First Incubation Project
The Continuous Delivery Foundation (CDF) has accepted Screwdriver as its first incubation-stage project, roughly one year after the foundation’s launch. Screwdriver is a container-focused build and CI/CD service that aims to simplify continuous delivery workflows at scale.
What Is Screwdriver?
Screwdriver originated at Yahoo, where it was initially developed as a simplified interface on top of Jenkins. The project was open sourced in 2016 and subsequently rebuilt from the ground up to address large-scale deployment requirements and modern CI/CD goals.
According to the Screwdriver project itself, the platform is “a collection of services that facilitate the workflow for continuous delivery pipelines.” Its feature set targets practical DevOps workflows directly:
- Automated testing of pull requests
- Building merged commits
- Deploying to any target environment
- Defining load tests and canary deployments
- Orchestrating multi-environment deployment pipelines
Screwdriver’s current integrations include GitHub, BitBucket, Helm, PostgreSQL, Nomad, and MySQL, making it adaptable to a range of infrastructure and tooling choices.
CDF’s Existing Project Portfolio
Prior to Screwdriver’s acceptance into incubation, the CDF’s project roster consisted entirely of graduated projects. These include:
- Jenkins – the widely used open-source automation server, backed by CloudBees
- Jenkins X – a cloud-native CI/CD solution for Kubernetes, also from the CloudBees ecosystem
- Spinnaker – Netflix’s multi-cloud continuous delivery platform
- Tekton – a Kubernetes-native CI/CD framework, originally contributed by Google
Screwdriver is notably different in origin: rather than coming from a major CDF backer such as CloudBees, Google, or Netflix, it emerged from Yahoo — a company since absorbed by Verizon.
Why the CDF Incubation Model Matters
The CDF’s incubation tier provides projects with vendor-neutral governance, community resources, and a clear growth path. For Screwdriver, joining the foundation offers an opportunity to accelerate development and broaden adoption beyond its current community.
“By joining the CD Foundation, Screwdriver will be able to scale more quickly, taking greater strides forward in development and deployment. With so many supported integrations, Screwdriver provides the openness and flexibility that DevOps teams require.”
— Dan Lopez, CDF Program Manager
CDF Also Launches an MLOps Special Interest Group
Alongside the Screwdriver announcement, the CDF announced the formation of a new MLOps Special Interest Group (SIG). The SIG is intended to bring structure to a rapidly growing but fragmented domain where machine learning models are produced in large numbers but their deployment and operational management often lack standardization.
The MLOps SIG’s stated goals include:
- Creating a shared vision and roadmap for MLOps
- Producing a reference architecture for ML deployment pipelines
- Developing design patterns, implementations, and operational processes for MLOps
- Addressing AI governance, risk management, and ethical AI principles
The formation of this SIG reflects growing recognition that continuous delivery principles need to extend into machine learning workflows — an area where tooling and best practices are still maturing.
Key Takeaways for DevOps Teams
- Screwdriver is now under CDF governance, which may improve its long-term support and development trajectory.
- Teams evaluating CI/CD tools should consider Screwdriver alongside Jenkins, Tekton, and Spinnaker — particularly if they need flexible multi-environment pipeline support.
- The new MLOps SIG signals the CDF’s intent to expand its scope beyond traditional software delivery into AI/ML operations.
