Show HN: Harness Relay – the coding agents you have, working together

Agentic System Lab released Harness Relay, an open-source desktop app that coordinates multiple coding agents on a single task, with the project posted to Hacker News as a Show HN entry. Harness Relay lets a lead agent design a team from Claude Code, Codex, Grok, Cursor Agent, Antigravity, GitHub Copilot CLI, Muse Code and five open-source coding agents on user-supplied model backends, assigning each member's role, model and turn order for confirmation before the agents work on the user's code and respond to each other. The app also includes voice input, notifications, conversation branching, task scheduling and PWA mobile support.

If you already have multiple coding agents(one kind of agent also works though), you should really look into this project! It's a desktop app that brings coding agents working together, with user experience similar to ChatGPT! One kind of agent is enough for an agent team: all of one kind, or any mix of Claude Code, Codex, Grok, Cursor Agent, Antigravity, GitHub Copilot CLI, Muse Code and five open-source coding agents on your own model backends. For each question, the lead agent designs the team: each member’s role and model, and how they take turns. Once you confirm it, the real agents on your machine work on your code, or any question, and answer each other.

It also supports voice input, notification, branching in conversation, task scheduling, and mobile app(PWA) support!

If you are interested in this project, please give it a try and star us on the GitHub repo, thanks!
