Reviewer scorecard
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“One command to expose localhost. Essential for webhook development and quick demos. The inspection UI is useful.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Simple tool that solves a real problem. The free tier is enough for development. Cloudflare Tunnel is the free alternative.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
“Cloudflare Tunnel provides similar functionality for free. ngrok's paid features need to differentiate more.”
