Lupine Systems
A small studio building software that respects the people who use it.
We build apps and tools with privacy, user control, and real infrastructure experience baked in from the start - not bolted on once something breaks.
What we care about
We come from infrastructure and SRE backgrounds, which is a long way of saying we have spent a lot of nights being paged for other people's design decisions. That shapes how we build.
Privacy by default
Sensitive data is encrypted at rest, minimised where we can, and never quietly sold or mined. No telemetry creeping in through the back door.
User control
Your data is yours. Export it, self-host it, or walk away with it. We design for the day you want to leave, not just the day you sign up.
Built to run
We operate what we build. Things are designed to be observable, recoverable, and boring in production - the good kind of boring.
Open where it counts
Our flagship work is open source and self-hostable. One codebase, no proprietary forks, no "enterprise" features held hostage.
Sheaf
Our flagship project is Sheaf, an open-source, self-hostable plural system tracker - a credible, sustainable replacement for SimplyPlural.
It is built the way we wish more software was: data encrypted at rest, treated as the sensitive information it is, fully exportable, and runnable on your own hardware with a single docker compose up. There is a hosted instance too, for people who would rather not run their own.
More to come
Sheaf is the largest thing we run today, but it is not the whole company. We have more apps in the works (mostly on the Android side for now) and we take on a limited amount of consulting around infrastructure, reliability, and backend work.
If any of that sounds like your kind of thing, say hello.
