Open-Source: Free, customizable, supports 75+ LLMs (OpenAI, Anthropic, Google, local models).
Terminal-Native: Responsive TUI with themeable interface, ideal for CLI enthusiasts.
Features: LSP integration for codebase awareness, session sharing via URLs, multi-AI support.
Performance: Flexible but may reformat code unexpectedly; newer, less polished.
Cost: Free, no subscription needed.
Setup: Easy install via Node.js; supports custom commands and MCP for tool integration.
Proprietary: Built on Claude Opus 4, requires Anthropic subscription (costly, ~$10-15/PR).
Terminal-Native: Deep codebase understanding, excels at multi-file edits and reasoning.
Features: Superior context handling (200K tokens), clear explanations, GitHub/VS Code integration.
Performance: 72.7% SWE-bench accuracy, outperforms OpenCode (69.1% with Codex CLI). Slower but more reliable for complex tasks.
Cost: Premium pricing, higher token usage.
Setup: Streamlined but tied to Anthropic’s ecosystem.
My Verdict: OpenCode is ideal for cost-conscious developers needing flexibility and open-source customization. Claude Code shines for enterprise-grade, complex projects with superior reasoning and integration, but at a higher cost. Choose based on budget and project complexity.
