🇹🇼 中文版
A small collection of free tools I built myself, one at a time. No sign-up, no login — just open the page and use it. I add new ones whenever I run into something in daily life or work that could use a tiny tool of its own.

- Free to use, no login required

Travel Deals Hub — Hotels, Tickets, eSIM & Transfers, One Page
Time-limited campaigns you can actually book from Taiwan, plus the booking, ticket, eSIM, transfer and car-hire platforms worth keeping — with comparison tables for when several platforms sell the same thing. Written for people living in Taiwan and booking in English.

Also available (Chinese only for now): a UTM link builder for tagging your campaign links.
FAQ
Are these tools free?
Yes, completely free — no hidden costs, no subscription required.
Do I need to sign up or log in?
No, just open the page and start using it — no account needed.
Does it work on mobile?
Yes, the page is designed mobile-first, so it works well straight from your phone’s browser — no app to install.
What does the “Affiliate links” tag mean?
Some of the links on that page are affiliate links. If you book through one, I may earn a small commission at no extra cost to you, and it doesn’t change the price or the offer you see. Platforms are ordered by how useful they are, not by what they pay.
How often are new tools added?
There’s no fixed schedule — I add a new one whenever I think of something useful. Suggestions are always welcome in the comments.
Support These Tools
I build and maintain these tools on my own, and keep them free for everyone. If one of them helped you, a coffee goes a long way toward keeping me building more.

Curious how these tools get built? I write about using AI tools to build things like this (in Chinese, for now) — check out the Claude AI Tutorial section. You might also like the app series I’m building.
