We build the system we wanted to use
Koala UI started as the component library behind our own products. Today 4,100+ teams ship on it.
Six things you stop building yourself
The parts every product needs and nobody enjoys writing twice, already done and already consistent with each other.
Sign-in and accounts
Email, passkeys, and social sign-in, with sessions, invites, and password resets handled. No auth server to host or patch.
Billing and plans
Subscriptions, trials, coupons, and invoices wired to your pricing page, so an upgrade never waits on an engineer.
Roles and permissions
Owners, admins, and members out of the box, plus custom roles when you need them. Every check runs on the server, never in the browser.
Email and notifications
Transactional email, in-app alerts, and weekly digests from one set of templates, so every message sounds like the same product.
A full audit log
Every change and export recorded with who, what, and when. Filter it, export it, or stream it to your own warehouse.
Usage analytics
Events tracked from day one, with funnels and retention ready to read, so you know whether what shipped actually landed.
A closer look, one panel at a time
Click a panel to bring it forward. The rest tuck into the rail, so the screen you care about always gets the room.
Numbers with a team behind them
From the teams shipping on it to the parts in the box, these figures trace a system built to feel finished.
Loved by the teams who ship on it
Recognized for accessible, polished components that arrive finished, not almost-finished.
The people behind every component
Designers and engineers who ship the system they use every day, from the first token to the last template.
