A month ago I had ideas for and but no dev team So I just started vibe coding Prayer times, petrol prices, ringgit tracker, flood alerts, cuti planner, a live PENGU dashboard with labeled whale wallets All shipped solo with AI Last week I thought of a cuti planner feature at 2am. By 7am it was live with support for all 16 states and calendar export. That used to take a sprint cycle minimum I spent years managing product teams and writing PRDs. Now I write prompts and ship before breakfast Vibe coding will not replace real engineering for complex infra. But for a solo founder who wants to validate fast and ship tools people actually use? Nothing else comes close right now 🚀
