Key Findings

  • Claude Code wins for serious repo work: The developer finds it smoother overall, citing the tight Claude-native workflow as a major advantage. After Anthropic increased Claude Code usage limits following the May 6 update, the author remains committed to it for production use.
  • OpenCode excels at model flexibility: The author sees OpenCode as the tool to use when experimenting with different models and providers, such as Kimi K2.6, GPT, Gemini, Qwen, and local models. It's a great option for trying new models without being locked into a single ecosystem.

The full technical breakdown dives into the internals of both tools — how they handle context windows, agent memory, subagent orchestration, permission systems, and safety controls. The author also references studying Claude Code's recent leak to inform the comparison.

Takeaway: For developers working on large, serious repositories with a need for reliability and smooth agentic workflows, Claude Code is the current recommendation. OpenCode is a strong secondary tool for model experimentation and multi-provider flexibility.
