Grok CLI vs OpenCode (2026): Which Vibe Coding App Is Better?

Both are popular terminal coding agents. Here is how Grok CLI and OpenCode stack up on price, strengths and weaknesses, and which one we would pick.

Grok CLI

Open-source terminal coding agent for xAI's Grok API with search, media generation and remote control

7.0 /10

Pricing: Open source

Pros

Fully open source (MIT) with a broad, well-documented feature set: sub-agents, MCP, lifecycle hooks, a microVM sandbox, and headless/CI-friendly modes
Backed by a real org (superagent-ai) with CI, changelog and clear troubleshooting docs

Cons

Main branch's tip commit is from May 2026, several months before this review, suggesting a slower recent cadence
Desktop automation and Telegram remote control widen the attack surface; sandboxing is Apple-Silicon-only, so Linux/Intel Mac runs are unsandboxed
