OpenCode and Goose are both open-source, model-agnostic agents that run in the terminal, but they emphasize different things. Goose is built around MCP extensibility with desktop and CLI surfaces. OpenCode is terminal-first and focused. The split is extensibility versus focus.
Summary
| Dimension | OpenCode | Goose |
|---|---|---|
| Surface | Terminal TUI | Desktop app + CLI |
| Extensibility | MCP supported, focused | MCP-native platform |
| Architecture | Client-server | Extension-driven |
| Models | Any provider, BYO key | Any provider, BYO key |
| Backing | Community | Block |
| Best for | Lean terminal agent | Heavily extended workflows |
Extensible vs Focused
Goose treats the agent as a platform. Because it is MCP-native, you add capabilities, connect data sources, and bolt on tools through extensions, and you can drive it from a desktop app or the CLI. If your plan is to integrate the agent deeply into many systems, Goose is built for that.
OpenCode treats the agent as a focused terminal tool. It supports MCP, but its emphasis is a clean, portable agent loop in the shell with a client-server design. If you want a lean agent without managing a platform of extensions, OpenCode is simpler.
Where OpenCode Wins
Lean terminal focus
A clean agent loop without platform overhead.
Client-server sessions
Attach and detach from a running agent.
Portable
Runs anywhere a shell does, including remote.
Where Goose Wins
MCP-native extensibility
Add tools and integrations through extensions.
Desktop and CLI
Two surfaces for different working styles.
Block backing
Maintained by Block with steady development.
Decision Framework
| Your priority | Best choice | Why |
|---|---|---|
| Heavy tool integration | Goose | MCP-native extension platform. |
| Lean terminal agent | OpenCode | Focused client-server loop. |
| Desktop app option | Goose | Has both desktop and CLI. |
| Remote / SSH work | OpenCode | Runs in any shell. |
| Avoid platform overhead | OpenCode | Simpler, focused design. |
Frequently Asked Questions
Is OpenCode or Goose better?
Goose for heavily extended, MCP-driven workflows; OpenCode for a lean, focused terminal agent.
What is Goose?
Block's open-source, MCP-native agent with desktop and CLI surfaces, model-agnostic and free.
Are they free?
Yes, both free and open source. You pay only for the model API.
Which is more extensible?
Goose, by design. OpenCode supports MCP but emphasizes focus over a broad extension platform.

WarpGrep Boosts Any MCP Agent
WarpGrep v2 adds 2-3 points on SWE-bench Pro to every model tested. It runs as an MCP server inside OpenCode, Goose, and any tool that supports MCP. Better search means better context means better code.
