Grok Build CLI

L'agent de codage natif en terminal de xAI avec sous-agents parallèles et workflow en mode plan

Verdicts par tâche

Fast inline code completionGitHub Copilot l’emporte

Copilot's IDE-native completion is the gold standard across 6+ editors at $10/mo

Grok Build CLI has no inline completion — it's a terminal agent, not an editor plugin

Autonomous multi-file refactoringGrok Build CLI l’emporte

8 parallel sub-agents in isolated worktrees compound for large migrations

But the security upload channel makes it unsafe for production codebases

Production/proprietary codebase workGitHub Copilot l’emporte

Enterprise-grade security with IP indemnity, SAML SSO, and no undisclosed uploads

Grok Build CLI's undisclosed full-repo GCS upload is a hard blocker for any code with secrets

Multi-IDE teamsGitHub Copilot l’emporte

Only tool that supports VS Code, JetBrains, Neovim, Xcode, Eclipse, and Visual Studio

Grok Build CLI is terminal-only with no IDE integration

Plan-first workflows with human gateGrok Build CLI l’emporte

Plan Mode requires explicit human approval before any file is touched

Copilot's agent mode can edit files without an explicit plan-review gate

Cost-predictable AI codingGitHub Copilot l’emporte

Free tier available; Pro at $10/mo includes unlimited completions

Grok Build CLI starts at $99/mo intro price, $299/mo at full price — 30x Copilot Pro
