OpenCode

Overview

OpenCode is an open source AI coding agent.

Project Details

• Project Repository: opencode
• Container Image: GitHub
• Documentation: Docs
• Reverse Proxy Port: 4096

Getting Started

1. Start the container: docker compose up -d
2. Open http://localhost:4096 in your browser
3. Follow the initial setup wizard to configure the application

Environment Variable Notes

OPENCODE_PORT – default: 4096
OPENCODE_HOSTNAME – default: 0.0.0.0

Volume Notes

With VOL_PATH=/data:

Container path	Host path	Purpose
/config	/data/opencode/config	Config files (config.json), also $HOME
/data	/data/opencode/data	OpenCode state, incl. auth.json from /connect
/projects	/data/opencode/projects	Workspace/project files

Network Notes

Requires proxy network

Docker Run

docker run -d \
  --name opencode \
  -p 4096:4096 \
  -v /data/opencode/config:/config \
  -v /data/projects:/projects \
  ghcr.io/anomalyco/opencode:latest

See compose.yaml for the full set of environment variables.

Additional Notes / Gotchas

This is a shared, reusable compose file — it ships "ready to use" but not pre-authenticated. Whoever runs it needs to /connect a provider (OpenCode Zen or OpenCode Go) before the agent can actually make model calls. Because HOME and XDG_DATA_HOME point at the /data bind mount, that login persists across container recreation.

Config file

The config.json at opencode/config/config.json is pre-configured to use OpenCode Zen cloud models — no local model runtime required. Default model is opencode/deepseek-v4-flash-free (free tier).

Run /connect inside the TUI to authenticate with OpenCode Zen (or another provider) and /models to switch. Login is persisted to the /data bind mount, so it survives container recreation.

For a flat-rate bundle of open-source models instead of pay-as-you-go, see OpenCode Go ($10/mo subscription, ~12 models including DeepSeek V4, Qwen 3.6, GLM 5.2) — switch to it the same way via /connect and /models.

To use a custom config with VOL_PATH=/data, copy it to:

/data/opencode/config/config.json

Model Guides

See the docs/ directory for best-practice guides on supported models:

• DeepSeek V4 Flash Free — free model via opencode provider (default)
• Claude (Anthropic) — paid model via API key

CLI Cheatsheet

From the opencode/ directory, prefix commands with docker compose:

# Start the web UI
docker compose up -d

# Attach TUI to the running server
docker compose exec opencode opencode

# Run a one-off command (replaces the "serve" command)
docker compose run --rm opencode opencode stats

# Common commands (via exec or run)
docker compose exec opencode opencode models --refresh
docker compose exec opencode opencode models
docker compose exec opencode opencode stats
docker compose exec opencode opencode stats --models --days 7
docker compose exec opencode opencode session list
docker compose exec opencode opencode auth list
docker compose exec opencode opencode db path
docker compose exec opencode opencode upgrade

Inside the TUI

/init          # Analyze project, create AGENTS.md
/models        # Switch model
/connect       # Add API key for a provider
/undo          # Undo last change
/redo          # Redo undone change
/share         # Create share link
