GitHub Copilot is an AI assistant for software development. It can suggest code, explain repositories, edit files, review changes, and work on assigned tasks that developers can inspect as pull requests.

synth-city
Synth City, formerly Claude Deck, is a self-hosted local control plane for coordinating coding-agent teams on GitHub issues through to reviewed pull requests, with a dashboard for progress, decisions, and human oversight.

About this product
Synth City keeps GitHub as the source of issues and pull requests while a local Deck controller observes and intervenes in bounded coding-agent attempts.
A factory is a supervisor, the Deck controller, and a team working a GitHub backlog, with a human Director owning the outcome and retained decisions.
Key Features
- Overview, Work, and Repositories show complete filtered work counts, owners, waiting reasons, PR context, and watched-scope intake.
- Harnesses provides an operations and readiness catalog for implemented providers with guarded native pages.
- A config editor browses, inspects, and edits Claude Code JSON settings or Codex TOML settings, including profiles and feature flags.
- MCP Servers can be added, edited, tested, and managed with OAuth support, registry browsing, and views of tools, resources, and prompts.
- Agent Bridge discovers and monitors agent tmux sessions and can attach up to four terminals in a 2x2 grid with per-pane controls.
- Agent Mail coordinates local agents through durable per-repo identities, structured context requests, handoffs, and a team mailbox.
- Agent Teams saves reusable rosters of agents and launches or reuses their sessions.
Use cases
- Deliver work from a GitHub issue backlog with a Leader directing implementers and verifiers toward reviewed pull requests.
- Inspect owners, waiting reasons, and PR context in the dashboard before approving a protected remedy.
- Coordinate mixed teams across Claude Code, Codex CLI, GitHub Copilot CLI, OpenCode CLI, and Pi sessions.
Who it is for
- Technical operators with existing repositories, local agent CLIs, native toolchains, and their own model credentials.
- Teams that mix harnesses and need to keep human decisions in the loop.
Requirements
- Python 3.11+
- Node.js 22.12+
- At least one supported local agent CLI on the same host: Claude Code, Codex CLI, GitHub Copilot CLI, OpenCode CLI, or Pi
- Linux for agent-team pane binding
Quick Start
- Clone the repository with git clone https://github.com/adrirubio/claude-deck.git and change into the claude-deck directory.
- Run ./scripts/install.sh for the native install path.
- Run Deck in the same environment where agent CLIs and credentials are installed, with at least one supported CLI present.
Limitations and considerations
- Docker is not supported because containers cannot see host-installed CLIs, tmux sessions, or native agent credentials.
- Finished is a tracking state, not independently reviewed delivery, reliability, cost, or time saved.
- Cost is unknown, and configuration checks do not verify model access.
License and links
Code license: MIT
Privacy and data
- There is no Deck cloud account and no Deck telemetry sent elsewhere; GitHub and native CLIs use their configured services and credentials.
- Deck reads and writes real local agent configuration files, so UI changes affect actual files and backups are advised before major edits.
