Our verdict

Claude Code lets one senior engineer ship a SaaS MVP from zero in 2-3 weeks: the CLI handles refactors, tests and commits end-to-end. Raw Opus 4.7 API gives you the same brain but forces you to build the agent harness yourself. For agencies and MVP builders, Claude Code wins on time-to-client-demo.
