Initial version was super minimal, but then, a lot of people started using it. So, revamped it into full product and launched it. Currently hosting over 300 sites, with 10 new sites getting added daily. All free for now. I personally has 53 sites as of now.
Sample stuff of mine:
1. [latency-numbers-2026] - https://latency-numbers-2026.pagey.site/
2. [NVIDIA (NVDA) — The Short / Underperformance Thesis] - https://nvidia-stock-analysis.pagey.site/
3. [Shamir's Secret Sharing] - https://shamirs-secret-sharing.pagey.site/
4. [Build Software Like It Needs To Last] - https://building-software-the-right-way.pagey.site/
5. [NPM Supply Chain Attack Techniques] - https://npm-supply-chain-attack-techniques.pagey.site/
6. [NPM Ecosystem Threat Report (May 19, 2025 - June 1, 2026)] - https://npm-supply-chain-attacks-25-26.pagey.site/
It was able to query csv, json, parquet and xlsx files, all locally. You could also mix files of different types in single session, and, manage multiple sets of files as individual sessions that you can switch easily whenever needed.

I had no idea this project would one day become my full-time job!
Looking back, I regret not open-sourcing more of our internal tools. It turned out to be one of the best ways to discover whether a product had real traction.
At the time, I struggled to justify open-sourcing our internal frameworks to my co-founders and investors. They preferred to keep them proprietary and treat them as trade secrets. However, most of the frameworks that remained internal have become increasingly difficult to maintain over time and now carry much greater long-term risk. They generate maintenance costs without creating enough value in return to justify their existence.
Fortunately, Carbone was an exception!
