kdcube vs rllm

kdcube: KDCube is an open-source, self-hosted production runtime designed for AI applications and agents, providing the necessary infrastructure to run frameworks like LangGraph, CrewAI, or custom agents in production. It handles multi-user serving, ordered conversation delivery, streaming, isolated code execution, cost controls, and secure deployment from Git, allowing developers to focus on agent logic rather than operational complexities.; rllm: rLLM is an open-source framework designed for post-training language agents using reinforcement learning. It allows users to easily build, train, and deploy custom agents and environments for real-world workloads.
