The App Factory
Make your own software — the quirky tools no catalog would ever carry. Free, open,
and keep it. May the Forge be with you.
The Swiss Knife is the version we forge for you. The App Factory is the other half of the same belief: that you should be able to make your own tools, too — not rent a builder, not sign into a platform, not have your creations live on someone else's cloud. Just open a file, make a thing,
and keep it.
It is a single HTML file. Open it in any browser and you have a small workshop: a code editor with a live preview, a shelf for the apps you make, and one button that matters — export, which hands you your finished app as one self-contained HTML file that runs offline, forever, on any machine. No account. No server. No telemetry. Nothing you write ever leaves your browser, because there is nowhere for it to go.
Why we're giving it away
A philosophy you only ever sell against is just marketing. This one we'd rather hand you. The App Factory is free and open source under the MIT licence — fork it, change it, and sell what you build with it. We think the purest form of "own your software" is owning the means to make it.
For the kind of person who reads the manual
This is a gift, not a product, so it comes with the honesty a gift deserves: there is no support line. No help desk, no ticket queue. The App Factory is for the person who reads the manual, opens the console, and figures it out — and because that's who it's for, we wrote a very good manual and left the source wide open. If you make something wonderful, we'd love to see it at hello@offline.ltd. We can't promise a reply, but we do read.
The one boundary
Apps you forge here are yours, completely — but they cannot be forged into a Swiss Knife by us. The Blades and Tools in the catalog are ones we make, test, document, and stand behind; home-forged apps live outside that, by design. The Factory is your workshop; the catalog is ours. Both are the point.
Own your work
Export your apps as files and keep them the way you'd keep anything that matters — a copy on your machine, one on a drive, one somewhere safe. The exported file is the thing you truly own. It is the same discipline the Swiss Knife teaches, in a workshop you run yourself.
