Software that doesn't waste your time

Bantamweight tools that punch above their weight: zero dependencies, zero network calls, one small binary that starts before you blink and phones no one — ever.

How we train

House rules

Four rules, no exceptions. They're why every app on the card weighs what it does.

1

No dependencies

Every library is somebody else's supply chain. We compile against the operating system and nothing else — what you audit is what you run.

2

No network

If a tool doesn't need the internet, it doesn't get the internet. Nothing is sent anywhere, because nothing can be.

3

One file

No installer, no background services, no registry sprawl. Copy it to run it. Delete it and it's gone without a trace.

4

Fast is respect

We don't build in features nobody cares about. We build in speed. Cold start is measured in milliseconds — the best splash screen is none.
