Our story
We build the groundwork, so you can build the product
Stack is a small team of design engineers. We turn the work every app repeats into one codebase that looks finished on day one.
Why we started
Sign-up, teams, billing, a dashboard, docs, a marketing site. We rebuilt them for every launch, and each time they came out a little different and a little unfinished.So we built them once, on Once UI, and kept building until they felt like a product rather than a starter. One config sets your brand, and every page follows.Today Stack is the codebase we start our own products from. It's yours to rename, reshape and ship.Every new product began with the same month of setup
What we believe
Four rules we build by
They decide what goes into Stack, and just as often what stays out.Design comes first
Every page ships finished, in dark and light, on phones and desktops.Your code, not ours
No lock-in and no hidden services. You own every file and can change any of it.Opinions, written down
Sensible defaults with the reasons beside them, so people and agents read the same map.Built in the open
We shape the roadmap with the people who build on it, in public.Team
The people behind Stack
A small team that designs, builds and answers your emails.
