Description: Comparison of Claude Code vs Codex building a Typeform-like app, with side‑by‑side analysis of outputs, cost, time, testing, and agent orchestration.
– Experiment setup: identical /goal prompt used; both built production-ready Typeform alternatives and were tested interactively.
– Findings: Claude Code (Formora) finished faster and cheaper with fewer tokens; Codex (Realform) produced heavier testing and a more mature backend architecture.
– Lessons: agents differ in orchestration, testing strategies and prompt-sensitivity; practical prompting and thorough end-to-end testing are essential.
Quotes:
One of them took 3 days, one of them took 5 hours, one of them spent $3,000, one of them spent $800.
Cloud Code did this about 11 times faster and 6.6 times cheaper.
You just don’t know what you’re going to get with these models.
