Wedding Planner is a complete, ready-to-use wedding planning application packed into a single HTML file. No server, no database, no build step and no external dependencies — open the file in a modern desktop browser and it works, even offline.
All data is stored locally in the browser (localStorage), with built-in backup and restore to a file. Nothing is sent anywhere.
The app covers the whole planning process in 17 sections: guest list, seating chart, budget, payments, vendors, timeline, checklist, invitations and more. The invitation module generates personalised PDF invitations for each guest and can export all of them at once as a ZIP.
The interface ships in 9 languages (English, Spanish, German, French, Italian, Russian, Chinese, Arabic with RTL, Hindi) and 5 colour themes.
Who it is for:
- Developers who want a finished product to rebrand and sell or offer to clients
- Wedding agencies and planners who need a private, offline tool
- Anyone studying how to build a full offline-first app in plain JavaScript
The source is plain, readable HTML, CSS and JavaScript — no frameworks, no obfuscation, no licence checks.
