Trestle
Local, code-aware secret scanner protecting your AI coding loop from API key leaks.
Overview
Trestle is a privacy-first, local secret scanner designed for modern AI-assisted development. It runs entirely on your machine, scanning for API keys, tokens, passwords, private keys, and certificates before they can be exposed. Integrated seamlessly into CLI, pre-commit hooks, IDEs like VS Code and Cursor, and MCP-compatible assistants, Trestle ensures that even the fastest AI coding agents can’t accidentally leak sensitive data. Its code-aware engine understands context, reducing false positives and catching leaks that traditional scanners miss.
With Trestle, you can maintain compliance and security without sacrificing the speed of AI-generated code. It logs findings locally, provides real-time alerts, and integrates directly into your existing git workflows.
