About

JavaEye is a one-person operation run by Nan Liang. I design, build, ship, and run a fleet of small free tools — schedulers, calculators, generators — each solving one concrete problem for one kind of user. Everything runs in the browser, nothing asks for a signup, and the whole fleet sits on Cloudflare's free tier.

This blog is the build log: what I'm making, what breaks, what the numbers say, and what I learn shipping in public. For the fleet itself, see the tools page.

The Measure-and-Show Method

Two rules every post on this blog follows, and every measured-data page is built around:

• Measure first. A number only appears on this blog if I counted it myself — traffic, indexing rates, quota limits — and the post says exactly how it was counted.
• Show the work. Claims about tools link to the shipped tool, and methodology claims link to the exact process, so anything stated here can be rechecked.
