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 🚀

“Graduation Radar” What it does, live and free (no API keys, no wallet connection, zero risk to your funds): •Streams every new token via PumpPortal’s free WebSocket and tracks trades in real time •Scores each token 0–100: curve progress, buy pressure (3 min), unique wallets, age (filters bundled fake pumps), net SOL velocity, minus a penalty if the dev wallet sells •Alerts with sound + optional push notifications when a token crosses your threshold in the graduation runway, plus a separate alert when tokens actually graduate •Built-in paper trading — one-tap hypothetical buys, live P&L, win rate, and average return that persist between sessions How to use it: open the page, let it run 5–10 minutes to populate, hit “Test alert” to check sound, and paper trade the signals for a week or two. If the stats panel shows a real edge after ~100 signals (needs roughly +15% average to clear fees and slippage), then consider tiny real position
