Claude Code vs OpenCode
Claude Code と OpenCode をワークフロー、価格、プライバシー、モデル対応、用途で比較します。
情報確認日 2026年8月29日
Claude Code
Claude Code remains a leading terminal-native coding agent. The August 2026 cost and feedback tools make it more useful for teams operating Claude-based applications, not just editing repositories.
OpenCode
OpenCode remains one of the strongest open and provider-flexible coding harnesses. OpenCode Go adds a simple $10 managed-model option without removing BYOK or turning the harness into a closed service.
主な違い
ワークフロー
Claude Code is Anthropic's terminal coding agent for repository work, subagents, hooks, MCP, and automation, with growing operational tooling for API cost analysis and feedback.
OpenCode is an open-source coding-agent harness for terminal, desktop, and IDE workflows with broad provider support, BYOK, and an optional OpenCode Go subscription for curated open models.

プライバシーとセキュリティ
Claude Code
Claude Code may process prompts, codebase context, command output, files, tool calls, and repository metadata to provide coding assistance. Privacy and retention depend on whether the user authenticates through a Claude subscription, Anthropic API, or cloud provider deployment such as Bedrock, Vertex AI, or Foundry. Users should keep secrets out of prompts and source files, use environment variables or secret stores, and review permissions before allowing agentic actions.
OpenCode
OpenCode states that it does not store code or context data by default, with processing happening locally or through direct API calls to the selected AI provider. The main exception is the optional /share feature, which uploads conversation data to OpenCode-hosted share pages and creates public links. Privacy depends on provider choice, local model usage, enterprise gateway routing, share settings, and whether sensitive files, secrets, or production data are included in context.
