Factory

Factory is infrastructure for running coding agents across Git repositories. Its Go control plane stores work, shows the worker fleet, and delegates tasks. Each Go worker owns one agent runtime, currently Codex or Claude Code.

The browser UI provides:

• an overview of execution throughput, reliability, cycle time, queue depth, and worker health;
• a work queue and task details;
• registered worker and repository status;
• task delegation using a title, prompt, repository, and worker.

Factory is local-first today. The server only accepts loopback connections and does not include user authentication.

Quick start

Requirements:

• Go 1.25 or newer
• Git
• curl
• just
• Codex CLI or Claude Code CLI, authenticated on the worker host

Node.js is only needed when changing the UI. Normal builds use the committed, embedded UI assets.

GitHub Automations and on-demand worker checkout depend on the GitHub CLI, gh. Factory does not include a separate GitHub API client. Install and authenticate gh on the control-plane host and each eligible worker host before enabling a GitHub Automation:

gh --version
gh auth status

just build
mkdir -p ~/.factory
cp examples/worker.toml ~/.factory/worker.toml

Edit ~/.factory/worker.toml to select codex or claude-code. Workers need no repository list. They probe local gh access and acquire centrally managed GitHub repositories on demand. Then start the server and worker:

just run

Open http://127.0.0.1:7337.

Existing factory-poller users must stop it and use Automations → Migrate legacy poller before removing their old configuration. Preview, Import, and Finalize each verify and lock the same legacy snapshot. Import creates disabled typed Automations and Finalize archives copies without deleting the originals.

One worker has one stable identity and one runtime. Run another worker with a different config and data directory when you want both Codex and Claude Code:

FACTORY_WORKER_CONFIG=~/.factory/claude-worker.toml \
  ~/.factory/bin/factory-worker

See the local guide for a complete setup and the worker guide for runtime and worktree behavior.

The control plane owns durable coordination. Workers own execution and Git worktrees. Workers poll the API, so the system does not require WebSockets or inbound connections to worker hosts.

All default state is below ~/.factory:

~/.factory/
  bin/
  server/factory.sqlite3
  config.toml       optional control-plane bootstrap only
  worker.toml
  workers/

Current scope

Implemented:

• Go control-plane API and embedded React UI;
• durable tasks, executions, attempts, leases, events, and cancellation;
• Codex and Claude Code workers;
• reusable versioned Workflows;
• disabled-first typed GitHub issue, GitHub pull-request, and schedule Automations evaluated by the control plane;
• a central managed-repository catalog, bounded worker caches, and isolated Git worktrees;
• bounded list APIs and retained-data metrics;
• automatic cleanup of clean unchanged or published work and preservation of unpublished branches.

Designed but not implemented: a unified factory CLI.

See the documentation index for current guides and proposed designs.

Development

Backend:

just test
just vet

UI:

just ui-install
just ui-check

After changing the UI, rebuild the committed assets:

just ui-build 0
