I will build a custom offline web app or business tool using vibe coding


Sobre este Serviço
I build custom offline web tools for small businesses, shops, and teams delivered as a single HTML file that works on any device, needs no installation, and costs nothing to run.
No subscriptions. No server. No technical setup. You open one file and it just works even without internet.
What I can build for you
- Inventory and stock management tools
- POS systems and daily sales trackers
- Staff rosters and attendance sheets
- Client and contact trackers (simple CRM)
- Expense and budget loggers
- Event and project planners
- Custom dashboards for any business data
- Family trees and relationship mappers
What you get
- A complete working tool, fully customised to your needs
- Clean, mobile-friendly UI that works on phone and desktop
- Local data saving (your data never leaves your device)
- Full source code you own it forever
I have built a full retail POS and inventory system (demand tracking, procurement, WhatsApp supplier ordering, analytics) and a feature-rich family tree builder (photo uploads, voice notes, relationship mapping, custom themes). Both run entirely offline as single files.
Tell me what you need and I will tell you honestly whether I can build it and how long it will take.

Perguntas frequentes
What exactly is a single HTML file tool?
It is a web app that runs entirely inside one file — no installation, no server, no account needed. You open it in any browser (Chrome, Safari, Firefox) on your phone or laptop and it works immediately. Your data is saved locally on your device, so it also works without internet.
Can multiple people use it at the same time?
Each person can have their own copy of the file on their own device. For a single shop or one operator this works perfectly. If you need multiple people to share live data in real time, that requires a backend — message me before ordering and I will tell you honestly if your use case fits.
Can you host it online so I can access it from a URL?
Yes. The file can be uploaded to Netlify or GitHub Pages (both free) to get a shareable public URL in minutes. I offer this as a gig extra. Note that it will still be a single-user tool — anyone with the URL can open it, but data does not sync between users.
What if I need changes after delivery?
Each package includes revisions (1 for Basic, 2 for Standard, 3 for Premium). After that, small updates are available as paid add-ons. Since you receive the full source file, any developer can also modify it — you are never locked in to working with me.
How do I tell you what I need?
Message me before ordering with a short description of what you want to track or manage, and who will use it. I will confirm what is possible, suggest the right package, and ask any clarifying questions. Most projects are clear enough to start within one conversation.
