keryx vs openhermit

keryx: Keryx is a fullstack TypeScript framework built on Bun, designed to write application logic once and deploy it across various transports, including HTTP, WebSocket, CLI, background tasks, and MCP (Model Context Protocol) for AI agents. It automatically exposes all actions as MCP tools, allowing AI agents to authenticate and interact with your application's validated endpoints with type safety.; openhermit: OpenHermit is an open-source platform designed for deploying and managing fleets of AI agents as production services. It centralizes internal agent state in PostgreSQL, isolates external workspace state in sandboxes (Docker, E2B, Daytona), and offers robust features like multi-channel integration and fleet-wide command execution.

Features

keryx logokeryx
01MCP-native actions: Every action is automatically an MCP tool with OAuth 2.1 authentication, typed errors, and per-session isolation for AI agents.
02Transport-agnostic Actions: A single action class handles HTTP, WebSocket, CLI, background tasks, and MCP tool calls with unified validation and middleware.
03Zod input validation: Provides type-safe parameter validation with automatic error responses and OpenAPI generation.
04Built-in background tasks: Utilizes node-resque for background job processing with fan-out patterns for parallel execution.
05Strongly-typed frontend integration: Offers end-to-end type safety for API responses with a companion Vite + React frontend, no code generation needed.
06Streaming responses: Supports SSE, chunked binary, and cross-transport streaming behavior for real-time data flow.
