cloister vs rllm

cloister: Cloister is a platform designed to bundle AI tooling and serve it through a single, traceable endpoint, compatible with various AI harnesses like Claude Code and Cursor. It ensures tools operate securely by isolating secrets, logging every call for auditability, and providing consistent deployment across local and production environments.; 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.

Features

cloister logocloister
01Secure Credential Isolation: Tools never directly access secrets; Cloister handles API calls, preventing leaks.
02Comprehensive Audit Trail: Every state-changing call generates a signed, tamper-evident receipt for verification.
03Consistent Deployment: The exact same configuration runs locally and deploys to Cloudflare Workers without modification.
04Protocol Agnostic Routing: Functions as an edge router and bundle host, supporting MCP and other HTTP-shaped tenants.
05Containerized Tools with Sandboxing: Each tool runs in its own sandboxed Workerd isolate for enhanced security.
rllm logorllm
01Open-source framework for reinforcement learning-based post-training of language agents.
02Supports building, training, and deploying custom agents and environments.
03Offers multiple training backends including 'verl' and 'tinker'.
04Enables LoRA and VLM training for advanced models.
05Includes AgentWorkflowEngine for training over arbitrary agentic programs.
