# What is Dagger?
|
|
|
|
Dagger is a universal deployment engine. Write your deployment logic once, run it securely from anywhere.
|
|
|
|
Key features:
|
|
|
|
* Escape YAML hell. Thanks to the Cue language, writing configuration is as fun and productive as writing code.
|
|
* A powerful declarative execution engine to automate even the most complex and custom logic
|
|
* Static type checking so you can catch configuration errors before running that huge deployment
|
|
* Built-in caching and parallelism for maximum scale and performance
|
|
* An ecosystem of reusable packages to save you time and share your expertise with the community
|
|
* Avoid CI lock-in: the same Dagger configuration can be used in any CI, or with no CI at all
|
|
* Rapid local development: test and run everything locally, in seconds.
|
|
* Deploy from CI or the laptop: no more duplicating your CI config in a Makefile just so you can perform a task locally.
|
|
* Native support for encrypted secrets
|
|
* Just-in-time artifacts: fetch, transform and produce any artifact on the fly: source repositories, container images, binaries, database exports, ML models...
|
|
|
|
Using Dagger, teams with different deployment workflows can more easily collaborate and deploy each other's software,
|
|
without being forced to change their tools.
|
|
|
|
Typical use cases:
|
|
|
|
* On-demand staging environments for reviewing code changes
|
|
* Manage CICD across multiple repositories and CI runners, with one unified configuration
|
|
* Iterate on infrastructure without disrupting development teams
|
|
* Lock down access to the production cluster so that only authorized configurations are applied
|
|
* Common ground between the PaaS, Kubernetes and Serverless siloes.
|
|
* On-demand integration environments for testing complex changes spanning several teams
|

## Dagger is alpha software
|
|
|
|
Warning! Dagger is _alpha-quality software_. It has many bugs, the user interface is minimal, and it may change in incompatible ways at any time. If you are still
|
|
willing to try it, thank you! We appreciate your help and encourage you to [ask
|
|
questions](https://github.com/dagger/dagger/discussions) and [report issues](https://github.com/dagger/dagger/issues).
