Phrony

The open runtime for production AI agents

107 followers

Phrony is where AI agents live, run, and stay under control. An agent starts as a few lines of code. In production, with real tools, budgets, and humans in the loop, it's not a function anymore. It's an entity, and code is the wrong place to keep it. Phrony lets you declare an agent in one YAML manifest, run it on an open runtime, and trace every run. Open spec, open-source, portable.
