Onecity is an independent product studio in Colombo. We turn real needs into working software — and we run what we build.
Onecity started with a simple frustration: too much software is built fast and abandoned faster. Half-finished, handed off, never looked after.
So we built a studio that does the opposite. We understand the real need, design and engineer the product around it, and then stay on to run it — hosting, monitoring, and improving it in the real world.
We're small on purpose. Fewer products, done properly. Today that means two live products — CoreScanly, iPhone verification for Sri Lanka, and NEZSIG, a crypto auto-trading platform — both designed, built, and operated in-house.
Based in Colombo. Built for everywhere.
The real problem comes before the brief. We build what people actually reach for, not what looks good in a deck.
No hand-off, no disappearing act. We stay responsible for our products long after launch.
Speed comes from clear thinking and good tools — never from cutting the corners that matter.
We'd rather build a few things properly than a hundred things halfway. Focus is the advantage.
Tell us what you need. We'll come back with a clear scope, a price, and a timeline.
