Overview
HarnessRouter is a Y Combinator-backed platform that provides a managed backend for running AI agents like Codex, Claude Code, and Hermes. It offers a single API to integrate these agents into your application, handling sandboxing, orchestration, retries, and cost controls. It's designed for developers who want to ship AI-powered features that produce real artifacts—code, files, videos, games—without building the underlying infrastructure.
DocsAlot CLI is a command-line tool and skill for coding agents (Claude Code, Codex) that focuses on documentation. It allows developers to create, pull, preview, migrate, and publish documentation sites using natural language prompts. The agent handles the workflow, while the developer stays in control with approval checkpoints.
