Greyline by The Meridian Lab

About

Greyline from The Meridian Lab functions as a managed reverse proxy. It identifies automated AI agents such as LangChain, AutoGPT, CrewAI, OpenClaw, and crawlers by analyzing 24 distinct signals. The service then interrogates, slows, or poisons these agents before they can access your actual infrastructure. Implementation requires just one CNAME record with no alterations to your code. In summary, deploy your own defensive agent to track and eliminate unwanted agents on your web assets.
