## Summary

Open-source programmable CI/CD engine running pipelines in containers; founded by Docker creator Solomon Hykes; supports 8 language SDKs and all major CI systems without lock-in; Daggerverse registry enables sharing and reuse of pipeline components.

## Company Overview

Dagger is an open-source programmable CI/CD engine founded in 2019 by Solomon Hykes, the creator of Docker. The company's mission is to eliminate the "push and pray" cycle of software delivery by letting teams define their entire pipeline as code — portable across any CI platform or local environment. Pipelines run inside containers, ensuring reproducible, isolated builds by default.\n\nDagger supports eight language SDKs including Go, Python, TypeScript, and PHP, letting developers write pipeline logic in the same language as their application. The platform integrates with all major CI systems (GitHub Actions, GitLab, CircleCI, Jenkins) without lock-in, and its Daggerverse module registry allows teams to share and reuse pipeline components. Primary customers are platform engineering and DevOps teams at software companies of all sizes.\n\nDagger has crossed 20,000 GitHub stars, reflecting strong organic developer adoption. The project is actively maintained with frequent releases and a growing contributor community. Hykes' track record with Docker — which became a foundational infrastructure technology — lends significant credibility to Dagger's vision of making CI/CD as portable and composable as containers made application packaging.

## Frequently Asked Questions

### What is Dagger?
Dagger is a programmable open-source CI/CD engine that runs pipelines in containers, allowing developers to define workflows as code and run them anywhere—locally, in CI, or in the cloud.

### Who created Dagger?
Dagger was founded in 2018 by Solomon Hykes, the creator of Docker, and is based in San Francisco.

### What makes Dagger different from other CI tools?
Dagger runs all tools in sandboxed containers, generates a DAG for concurrent execution, provides aggressive caching, and supports 8 language SDKs for writing pipelines as code.

### What is Dagger?
Dagger is an open-source CI/CD engine that lets developers write their pipelines as code — in Python, Go, TypeScript, or other languages — and run them locally or on any cloud provider without vendor lock-in.

### Who created Dagger?
Dagger was created by Solomon Hykes, the founder of Docker — bringing significant credibility and developer community recognition to the project given Docker's transformative impact on software delivery.

### How does Dagger differ from GitHub Actions or Jenkins?
Dagger pipelines are written in general-purpose programming languages (not YAML) and run identically on any machine — local laptop, CI server, or cloud — eliminating the 'works on my machine, breaks in CI' problem that YAML-based CI systems suffer from.

### What is Daggerverse?
Daggerverse is Dagger's public registry of reusable pipeline modules — pre-built components for common tasks like Docker builds, test runners, and deployments that developers can import and compose into their own pipelines.

### What is Dagger Cloud?
Dagger Cloud is the commercial managed service layer — providing pipeline visualization, caching, and observability on top of the open-source Dagger engine, enabling teams to scale their Dagger pipelines with enterprise-grade infrastructure.
