About
Aviation software, built by people who worked inside it.
We worked at airlines, GDSs and travel-tech startups. Active Flights builds the software we wanted then — careful with your data, exact with your numbers.
Why we build
Get the foundation right, and everything on top gets better.
Most teams rebuild the same schedule tools by hand, and the bill compounds every year. We read the file once, exactly — and every workflow stands on it. That foundation is SSIM Toolkit.
Who makes it
One company, one brand, its products.

The mark
The Big Dipper, in our colours.
For as long as people have flown, they have steered by the stars, and the Big Dipper points the way to the pole star. Our mark sets it on three bands — amber, crimson and cobalt — and every product wears the same bands in a symbol of its own.
Active FlightsSSIM ToolkitHow we work
The bets that shape every release.
Foundation first
We over-invest in correctness; the interface follows.
Deterministic by design
Same file in, same answer out — every figure traced to the standard.
Local & private
Your schedules stay on your machine. They are read and analysed there, and never uploaded.
No half-built UI
One feature less, rather than one without its empty states and its care.
Owned, not rented
A desktop app you install and own — not a service you log in to.
Calm density
Schedules are dense data; dense data deserves quiet, legible design.

SSIM Toolkit is free to download during the Early Access Preview, for macOS and Windows. Open your own schedule files and see what it does — or tell us what you are working on.
