About ShFengXiaoTech

What this site is

ShFengXiaoTech (https://shfengxiaotech.com) is a free collection of random generator tools that run directly in your web browser. Everything on this site is free to use, with no sign-up and no downloads required.

Our current tools include:

• Random Password Generator — create strong, secure passwords of any length with customizable character sets.
• Random PIN Generator — generate numeric PINs for locks, devices, and everyday use.
• Lorem Ipsum Generator — produce placeholder text for designs, mockups, and drafts.
• Random List Shuffler — shuffle any list of items into a random order.
• Coin Flip — a simple, fair virtual coin flip.
• Yes/No Decision Maker (Oracle) — get a random yes-or-no answer to help break a deadlock.

More tools are added regularly, all following the same principle: instant, free, and private.

Who it’s for

ShFengXiaoTech is built for anyone who needs a quick, trustworthy random result — developers prototyping with dummy data, designers filling mockups, students picking teams, teams running giveaways, or anyone who just needs a strong password or a fair coin flip. If you want a result without creating an account or handing over personal information, this site is for you.

Our privacy promise

Privacy is built into how our tools work. Every tool on ShFengXiaoTech runs 100% in your own browser. The passwords, PINs, lists, and results you generate never leave your device — they are never sent to our servers, stored by us, or shared with anyone. There is nothing to leak, because we never receive it in the first place.
