Reviewer scorecard
“Zero JS by default with islands architecture is the right approach for content sites. Performance is incredible out of the box.”
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“For content sites, blogs, and marketing pages, nothing beats Astro's performance. The multi-framework support is practical.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Content sites don't need SPAs. Astro proved that shipping less JavaScript is both possible and better.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
