Reviewer scorecard
“Clean UI, open source, and supports every protocol. The git-based sync is useful for teams.”
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“Lighter than Postman and open source. For most API development needs, it's the right balance of features.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Functional but the UI isn't remarkable. It gets the job done without inspiring joy.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
