Claude Code: our take
Claude Code is Anthropic's agentic coding tool: it reads your codebase, edits files and runs commands from the terminal or IDE. Strengths: it handles multi-file changes on real projects well, and it's included in every paid Claude plan, starting with Pro at $20/mo ($17/mo billed annually). Weaknesses: there's no free tier for Claude Code, usage limits reset in five-hour windows, and it's terminal-first, which can feel intimidating. Use it if you're comfortable in a terminal and want an agent that does real engineering work. Skip it if you want a point-and-click app builder; try Lovable or Replit instead.
OpenAI Codex: our take
Codex is OpenAI's coding agent, available as an app, in the CLI, in your IDE and in the cloud. Strengths: it's the cheapest way into a top-tier coding agent, with limited free access and fuller use bundled into ChatGPT Plus ($20/mo). If you already pay for ChatGPT, you already have it. Weaknesses: free access is limited and depends on rollout, and heavy users will hit usage limits or need pricier plans. Use it if you're new to vibe coding or already in the ChatGPT ecosystem. Skip it if you want everything inside one dedicated editor; Cursor may suit you better.
