I work with DSPy in Python and felt it was missing in the Ruby ecosystem.

So I started https://github.com/vicentereig/dspy.rb: a composable, type-safe version built for Rubyists who want to design and optimize prompts, and reuse LLM pipelines without leaving their language of choice. Working with DSPy::Signatures reminds me a bit of designing a db schema with an ORM.

It’s still early, but it already lets you define structured modules, instrument them in Langfuse, wire them up like functional components, and experiment with signature optimization. All in plain Ruby.
