Hey Product Hunt 👋 I'm Vikas, a solo founder from Pune. I've spent the last 15 years building frontends and SIEM tools, and one thing kept bugging me: every time someone wanted to look at their own data, the first step was uploading it somewhere. CSV in your inbox? Upload to a BI tool. Spreadsheet from a client? Upload to a warehouse. Even "just exploring" meant handing your data to a server you didn't own. So I built DuckViz — analytics that runs entirely in your browser. You drop a file (CSV, Parquet, JSON, Excel), and DuckDB-WASM gives you a real SQL engine, charts, and a dashboard you can save or embed. Nothing leaves your machine unless you choose to share it. It's built for two people: Analysts who just want a dashboard from a file in 30 seconds. Builders who want to drop into their own app — same engine, no backend. What's next: more data sources, AI-assisted dashboards (running locally where possible), and a richer SDK. I'd love your feedback — especially the awkward edges. What file did you try to load that didn't work? What chart is missing? Roast the onboarding. I'm reading every comment today. Thanks for taking a look — Vikas
