Friday: Run Claude Code and Codex as a Crew Open Source

A new open-source framework called Friday now lets developers run Claude Code and Codex as collaborative agent crews directly on their local machines. Officially released on November 1, 2026, the tool addresses a growing demand for multi-agent orchestration systems that operate without mandatory cloud dependencies. Friday enables developers to assign specialized tasks to different AI models while maintaining shared context across a unified project workspace.

What Friday Does

Friday functions as an orchestration layer that coordinates multiple AI coding agents in a crew-based workflow. Rather than relying on a single model for all tasks, developers can delegate frontend work to one agent, backend logic to another, and testing to a third. The framework manages inter-agent communication, context sharing, and task handoffs automatically.

The system supports both Anthropic's Claude Code and OpenAI's Codex, allowing teams to leverage the strengths of each model within the same project. Claude Code typically handles complex reasoning and architectural decisions, while Codex excels at rapid code generation and autocomplete scenarios. Friday's architecture ensures that agents can read each other's outputs and build on previous work without manual intervention.

Release Date and Availability

Friday was officially released on November 1, 2026, and is available now through its GitHub repository at github.com/splashxmoon/friday. The framework is distributed under an open-source license, enabling developers to modify, extend, and deploy the tool according to their specific workflow requirements. The initial release includes documentation for setup, agent configuration, and crew orchestration patterns.

Technical Architecture

The framework runs entirely on local hardware, eliminating the need for proprietary cloud services beyond the API calls to Claude Code and Codex themselves. Friday manages agent lifecycles, coordinates file system access, and maintains a shared knowledge graph that agents reference during task execution. Developers define crew structures through configuration files that specify which models handle which responsibilities.

• Local-first architecture with no mandatory cloud orchestration layer
• Configuration-driven agent assignment and task delegation
• Shared context management across multiple AI models
• Support for custom agent roles and specialized workflows

Developer Use Cases

Early adopters are using Friday for full-stack development projects where different agents own distinct parts of the codebase. One common pattern involves assigning Claude Code to handle database schema design and API architecture while Codex generates boilerplate and implements UI components. The framework also supports testing crews where one agent writes unit tests for code generated by another.

The tool is particularly useful for developers who want to compare model outputs side-by-side or maintain redundancy in critical code paths. By running multiple agents simultaneously, teams can evaluate different approaches to the same problem and select the best solution based on performance, readability, or other criteria.

What This Means

Friday represents a shift toward developer-controlled AI orchestration in local environments. As AI coding assistants mature, the ability to coordinate multiple specialized agents becomes increasingly valuable for complex projects. The open-source nature of Friday ensures that developers retain full control over their agent workflows without vendor lock-in, while the crew-based model acknowledges that no single AI model excels at every coding task. For teams already using Claude Code or Codex individually, Friday provides a framework to combine their strengths within a unified development process.
