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
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“CI pipelines in TypeScript instead of YAML. Local execution means you can debug pipelines on your machine.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“The YAML-to-code migration for CI is overdue. Dagger's approach of real programming languages is correct.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“CI/CD in real programming languages will replace YAML. Dagger is leading this inevitable transition.”
