Dagger lets you write CI/CD pipelines in your programming language — TypeScript, Python, Go. Runs locally and in any CI. No more YAML.
Reviewer scorecard
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“CI pipelines in TypeScript instead of YAML. Local execution means you can debug pipelines on your machine.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“The YAML-to-code migration for CI is overdue. Dagger's approach of real programming languages is correct.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
“CI/CD in real programming languages will replace YAML. Dagger is leading this inevitable transition.”
