## What it is
Screwdriver is an open-source, self-hosted build platform for continuous delivery, built as a pluggable collection of services (API, UI, log store, queue) in JavaScript. It lets teams define pipelines as code in YAML and run builds on Kubernetes, Docker, or Nomad executors with GitHub, GitLab, or Bitbucket SCM integration.

## Use cases
- self-host a CI/CD platform instead of Jenkins
- define build and deploy pipelines as YAML in the repo
- run containerized builds on Kubernetes
- automate testing pull requests and deploying merged commits
- set up multi-environment deployment pipelines with canary releases
- integrate CI with GitHub, GitLab, or Bitbucket via webhooks

## When to choose
- you want a self-hosted, pluggable CI/CD system with control over your own build cluster
- you need pipeline-as-code with YAML config stored beside your code
- you run Kubernetes or Docker and want container-native builds
- Jenkins no longer scales for your build volume

## When to avoid
- you just need a simple hosted CI service without operating infrastructure
- your team lacks capacity to manage a multi-service cluster (API, UI, store, queue)
- you need a CI tool with a large plugin marketplace like Jenkins or GitHub Actions
