Reviewer scorecard
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“The most feature-complete flag platform. Targeting rules, segments, and experimentation are production-grade.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Expensive for what amounts to conditional logic. PostHog flags, Vercel Flags, or Unleash cover most needs at lower cost.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
“Feature flags as infrastructure for safe deployment will be universal. LaunchDarkly defined the category.”
