splashxmoon/friday is an open-source harness that lets multiple coding agents collaborate on a single workspace. The latest release in the GitHub repository is v0.1.5. The provided information lists no changes for this version, so the specific changes in this release cannot be confirmed.
The project focuses on coordinating coding tools the user has already installed and signed in to from one place, dividing work among them. It says it supports nine more tools such as Claude Code, Codex, Cursor, Gemini CLI, and Copilot. The agents exchange messages with each other on the workspace and can hand work to another agent when they hit a usage limit. It also offers a mode where each agent takes a copy of the repository, and work is marked complete after a test run and a review by another agent. It runs locally without its own accounts or models, and supports macOS, Windows, and Linux. It is written in TypeScript and uses the MIT license.
That said, the described collaboration flow alone does not tell you how it performs in practice or whether adopting it pays off. The repository has 1 star, and no use cases or comparison data are given in FACTS. The change list for the latest release is also missing, so what can be confirmed now is only the feature description and the supported scope, and the real effect has to be verified separately.
