About DengShen

Small tools that do one thing well.

What this is

DengShen (神灯 — "magic lamp") is a small independent studio. It makes single-purpose web tools: each one does exactly one job, does it well, and gets out of the way. No accounts, no dashboards you'll never open, no feature creep.

How it's sold

Tools are sold as one-time purchases through a third-party payment platform — you pay once and keep using the tool. There are no subscriptions and no recurring charges.

Live tools

QRKeep — Dynamic QR codes that never expire. qr-never-expires.pages.dev
StatementGrid — Bank statement PDF to CSV/Excel. bank-pdf-to-csv.pages.dev

Each tool is moving to its own dengshen.cc subdomain. More tools are in demand-testing and appear here when they ship.
