See the truth about your APIs runi is an open-source API client that verifies what AI generates. When 46% of developers don't trust AI output (Stack Overflow 2025 Developer Survey), you need a second opinion. runi is that opinion.

runi is an open-source API client designed to verify AI-generated code against OpenAPI specifications, ensuring accuracy and catching API drift before production. It emphasizes a local-first, Git-friendly approach, requiring no account and keeping your data secure on your machine.

    Good for developers who want to catch API contract violations automatically.

    Truth-seeing approach is more reliable than trusting documentation alone.
