One Swiss Knife in the exact shape of your life.

Revenue Streams

A private revenue-mix tracker in one HTML file on your machine: every source, every month, drawn honestly.

Live · runs in your browser · no network

This is not a screenshot. It's the real tool, running right here: go on, put something in it.

Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.

Freelance money arrives from four directions in three moods, and "how's business?" deserves a better answer than a feeling. Revenue Streams keeps each payment on record — the source, the amount, whether it's retainer, project, subscription, royalty or other, and the date — so you can see what actually feeds you.

Manual:

What it keeps

Standing facts

In ten years

Whatever you put in (Stream / source, Amount, Kind and Date) stays inside the file itself. There is no account to lapse, no plan to be sunset, no migration e-mail with a deadline in it. A decade of revenue streams entries is a decade of your own handwriting, kept in a document you can back up like any other.

If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.

Getting your data out

Export to CSV from inside the tool and open it in anything: a spreadsheet, another app, a text editor. Or keep the HTML file: it is plain, readable, and inspectable; you can open it in a text editor and see your own rows sitting there. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.

Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.

Questions people ask

01

How do freelancers track income from multiple sources?

One entry per payment: where it came from, how much, what kind of income it is, and when it landed. After a few months the list shows you which streams are rivers and which are drips.

02

Is my income data safe in this tool?

It never travels, which is the safest arrangement there is. The tool is a single HTML file running offline in your browser — no account, no server, nothing leaves the page. Your numbers are yours alone.

03

Is this a replacement for accounting software?

No — it files no taxes and issues no invoices. It's the clear-eyed overview layer: what came in, from where, of what kind, so you can steer the business before the accountant sees it.
