A Chinese developer chronicles their experience building a Cloud Agent V1 using the Vibe Coding approach, starting in January 2026. Initially inspired by social media success stories, they quickly encountered real-world challenges: the system struggled with concurrent user loads, API costs spiraled, and maintaining the codebase became a nightmare. The author ultimately abandoned the project, sharing hard-won lessons about the gap between demo and production. Key takeaways include the importance of proper architecture planning, realistic cost estimation for LLM API calls, and the dangers of over-relying on AI-generated code without understanding the underlying logic. For overseas developers and indie hackers, this is a refreshingly honest counterpoint to the hype around Vibe Coding, offering practical advice for those considering similar projects.
