Foreword
Why this handbook existsThere is no upload button — because there is no server.
Your files & data never leave your browser. Computation happens in your browser’s own sandbox — no accounts, no analytics on your inputs, nothing to breach. Audit it yourself with the network tab: open any tool and watch it make zero requests.
No loading, no signup — answers in milliseconds.
Calculations finish in milliseconds, not minutes. Every tool opens directly in your browser and works offline once loaded — no queue, no processing screen, no waiting.
Free means free — forever.
The free edition is permanent: every one of the 231 entries in this handbook is fully functional the moment you open it — no signup, no watermarks, no hidden limits. Pro is optional and adds volume for professionals: batch runs, unlimited downloads, white-label exports and an ad-free experience.
Built for every state, every country.
Tax brackets for all 50 US states, business tools for global freelancers, and developer utilities for everyone — wherever you file, invoice, or ship from.
