About ZSKey

ZSKey is a practical micro-tools SaaS for individuals and small teams. We turn repetitive work in vertical scenarios - renovation budgeting, woodworking cut lists, crochet & perler design, unit conversion, image compression, PDF processing, and weather - into ready-to-use tools.

We believe small tools solve big problems: no feature bloat. Every tool targets one real, narrow pain point, is calculated accurately and used quickly.

The site serves both domestic and overseas users: a Chinese interface with WeChat & Alipay for China, and multilingual (zh/en/ja/ko/fr/es) with PayPal for the world.

Pricing is simple and transparent: free items stay free forever; Pro tools can be bought once or subscribed for all access.
