OpenCode

There is a terminal interface, a desktop app in beta with builds for macOS on Apple silicon and Intel, Windows x64 and ARM64, and Linux as AppImage, deb or rpm, plus a web interface. The web interface is reached with the opencode pair command, which prints a link that works once and expires after five minutes. All of them talk to a shared background server, so several clients can attach to the same running work, and Docker images are published for containerised setups.

Run /connect to add a provider with its credentials, then /models to select from the models.dev catalog and the providers you have configured. A default belongs in opencode.jsonc under the model key, and a single run can override it with opencode run --model provider/model. Providers that are not in the catalog can be declared as OpenAI-compatible endpoints with a base URL and an environment variable holding the key, which also covers proxies and self-hosted inference. OpenCode Go is an optional subscription for models tested by the OpenCode team, connected like any other provider.

The build agent has full tool access and the plan agent is read-only, denies file edits and asks before running shell commands; a general subagent handles broad searches and multi-step tasks. Custom agents live in markdown or JSONC with their own mode, model, prompt and permission set, and subagents use their own rules rather than inheriting the parent's. Permissions are allow, ask or deny rules with wildcards over actions such as shell, edit, read and subagent, the last matching rule wins, and approvals granted with Allow always are saved as project-scoped rules that never override a deny. Organisation policies applied through the Console can hard-deny a check after project rules run.

Yes. Add a remote server with a command such as opencode mcp add context7 --url https://mcp.context7.com/mcp, adding --global to make it available in every project, and check connections with opencode mcp list. Remote servers use OAuth by default, and any that report needs authentication are signed in through the /mcps dialog. Servers can also be declared by hand under mcp.servers in opencode.jsonc as a local command or a remote URL, with a disabled flag to keep one configured without connecting it.

Plugins can add tools, hooks, integrations, commands, agents and other behaviour, and they install with opencode plugin add using an npm name, version range, or a GitHub and SSH git specification, including private repositories your git credentials can reach. Local plugins live under .opencode/plugins and reload when their files change, while CLI-only plugins are configured separately in cli.json. You can list, check, update and remove plugins from the CLI, disable individual entries with a minus prefix, and the policy and Console provider plugins cannot be removed by a repository.
