Intro
OpenCode is used by millions every day. Build on top of it to create your own applications, integrations, and agent experiences without starting from scratch.
We also offer Effect APIs for plugins, clients, and embedded apps.
Extend OpenCodeRun it as a serverEmbed it
Build plugins that add tools, integrations, commands, agents, and custom behavior while keeping the rest of OpenCode intact.
Connect to OpenCode with the same client used by the TUI and desktop app, then build any interface, workflow, or agent experience around it.
Embed OpenCode directly into your application and build a completely custom agent, interface, or developer product around it.
