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
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“CI pipelines in TypeScript instead of YAML. Local execution means you can debug pipelines on your machine.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“The YAML-to-code migration for CI is overdue. Dagger's approach of real programming languages is correct.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“CI/CD in real programming languages will replace YAML. Dagger is leading this inevitable transition.”
