SchemaFit
CI linter for LLM structured-output schemas
SchemaFit is an MIT-licensed CI linter for LLM structured-output schemas. It checks JSON Schema, tool definitions, and response_format schemas against provider-specific constraints before runtime. It catches unsupported keywords, nesting issues, required/optional mismatches, and portability problems across OpenAI, Anthropic, Gemini, Mistral, and Cohere, so teams can fail PRs instead of production calls.
SchemaFit is a Open Source company. It launched on Product Hunt on Jun 29, 2026, with 9 upvotes. Adamlead has 1 person on file at SchemaFit.
