Parent LLC · est. for the long haul
A home for small,
well-made software.
KCB Systems is the umbrella for my personal projects — the ones I build to scratch a real itch, then give a proper name, a proper home, and the time they deserve.
Under the umbrella
What lives here
Each project gets its own identity and its own home. KCB Systems is just the workshop they're built in.
SwimKeeper
Active A private-by-default family swim journal. Log meets, results, and splits — then see all-time PBs, season bests, and goal progress at a glance. Your family's times, your control.
More on the way
In the workshopThe next itch is already being scratched. When it's good enough to share, it'll show up right here with a name of its own.
The person behind it
One builder, a few good ideas
Bryan Chain
// builder, tinkerer, dog person
I build software the way I'd want it built — small, focused, and genuinely useful. KCB Systems is the LLC I formed to give those projects a real home instead of letting them live and die in a side folder.
I write about the work, the tools, and the occasional tangent over on bryanchain.com. Everything here is built without investors, deadlines, or a growth team — just the standard of work I'm happy to put my name on.
