harnessrouter.org Observed source

Editorial interest 82/100 Selection signal · not a rating of the site

HarnessRouter runs Codex, Claude Code, Hermes, and other agent harnesses in isolated sandboxes so products can receive code, files, documents, and other finished artifacts.

Landing page captured for the 2026-08-24 issue.

Field notes

The service models an agent harness as more than a language model: it combines a sandbox, tools, an execution loop, files, sessions, and returned artifacts. Its public material includes a harness catalog, source-backed integration references, and a comparison of Codex, Claude Code, and Hermes on the same task. The page also outlines a three-step integration using AGENTS.md, a user request, and a securely stored API key, while deeper API use appears to involve an account and usage plan.
