About OpenDocuHub
We build client-side commercial paperwork utilities for independent professionals and small teams worldwide. Our tools generate vector PDFs entirely in browser memory without accounts, paywalls, or server data transmission.
Who we are
We are an independent software collective focused on utility software architecture. We believe that essential everyday business tasks, like generating an invoice, drafting a purchase order, or logging hours on a timesheet, should never require personal data trade-offs, intrusive tracking cookies, or subscription paywalls.
Our team designs lean, robust web applications that respect your device resources and your privacy. Everything we ship is crafted to execute directly on the client machine using open web standards.
Why we built it
Document generation on the web is broken. Traditional billing SaaS tools force users through mandatory account registrations, queue document jobs on remote servers, place arbitrary watermarks on exports, and quietly record sensitive client names and financial totals.
We built OpenDocuHub to eliminate that friction completely:
- Zero Remote Transmission: Invoices, line items, and financial records never touch our servers.
- Integer-Cent Arithmetic: Eliminates floating-point rounding errors and guarantees exact totals across every tax rate.
- True Offline Operation: Fully functional offline after initial load, ideal for work in transit or remote job sites.
- No Artificial Restrictions: No document limits, no required sign-ups, and no brand watermarks on your professional files.
Who uses it
OpenDocuHub is built for working professionals who need reliable documentation tools without administrative complexity:
Contractors and Trades
Electricians, plumbers, builders, and field specialists who need fast estimates, quotes, and work orders directly from a phone or laptop.
Freelancers and Consultants
Designers, software developers, and copywriters needing clean, unbranded tax invoices and hourly timesheets for global clients.
Logistics and Small Business
Warehouse handlers and exporters producing packing slips, commercial customs declarations, and delivery receipts in standard formats.
Where we stand
Our architectural commitments guide every product decision we make:
Absolute Data Privacy
Your business numbers, client directories, and invoices are stored strictly in your browser IndexedDB vault. We have no access to them, no tracking databases, and no server logs of your content.
Zero Subscription Paywalls
All generators, document templates, thermal receipt modes, and vector PDF exports remain completely free. We do not withhold core capabilities behind premium tiers.
Data Portability
You own your data. Our document vault allows full single-click JSON export and import so you can back up, transfer, or clear your history at any moment.
