Mantyl

Mantyl is a innovative developer tool designed to bring transparency and verifiability to AI-generated software. It compiles your code repositories, coding-agent history, and executed checks into a comprehensive, verified project passport that clients can independently re-run. This ensures that every claim about the project's state, checks, or proofs is clearly labeled by who proved it, fostering trust and accountability. Its free, local-first CLI supports popular AI models like Claude Code, Cursor, and Codex, and operates without requiring user accounts, making it accessible and privacy-conscious. Mantyl is ideal for developers and AI teams seeking to demonstrate the credibility of their AI-built software and maintain an auditable trail of project development and validation.
