harnessrouter vs agentenv-framework

harnessrouter: HarnessRouter provides a unified infrastructure layer that transforms various agent harnesses (like Codex and Claude Code) into plug-and-play backends, enabling products to run tasks, retrieve results, and switch between harnesses via a single API. It implements the Unified Harness Protocol (UHP) and offers an OpenAI Responses-compatible API for managing persistent sessions, streaming progress, files, and task lifecycle without complex harness engineering.; agentenv-framework: AgentEnv Framework is a Python SDK and CLI tool designed for building, deploying, and running agentic environments. It facilitates the creation of containerized agent servers, manages their deployment, and provides mechanisms to grade agent performance within these environments.
