Reviewer scorecard
“API collections in git, no account required, and offline-first. This is how API clients should work.”
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“One-time purchase vs subscription is refreshing. Git-native collections mean your API tests are version-controlled.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Offline-first, git-native tools represent a pushback against SaaS subscriptions. Bruno leads this movement in API tools.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
