OpenCode vs. Grok Build vs. Claude Code: which open coding agent should you actually build on
Three terminal-native coding agents, three different bets. OpenCode wagers on model freedom, Grok Build on parallel sub-agents, Claude Code on depth of tooling. Here’s how to pick the one that fits your team.
After the lead, the article contrasts the core philosophies behind the three agents: OpenCode emphasizes model neutrality and an auditable, optionally air-gapped architecture; Grok Build focuses on orchestration via parallel sub-agents with a plan-first approval gate; and Claude Code prioritizes composable primitives—like CLAUDE.md, skills, subagents, hooks, and MCP—to let teams deeply tailor behavior over time. It then explains the key “coding agent” concepts (tool use, multi-step planning, and permission boundaries), describes how each product’s architecture handles planning, context, and governance, and runs a shared, realistic soft-delete feature use case to show how they approach migrations, API changes, frontend updates, and testing differently. Finally, it maps each tool to practical scenarios (compliance/offline needs, provider alignment, high-throughput parallel work, or long-lived codebase customization), calls out common failure modes and best practices (scoping tasks, treating plan/read-only as review, configuring repo conventions, and reviewing diffs like PRs), and concludes with a decision framework: trial each tool against a real backlog item while judging fit to constraints rather than benchmarking alone.
