Built by People Who Care
We're a software development studio that believes business tools should be powerful, beautiful, and actually enjoyable to use.
How We Got Here
KLASTER started as a one-person operation. Frendy Lee, based in Indonesia, took on freelance projects — a real estate platform here, a VR tour for a Japanese city government there — and kept saying yes to the ones that felt too hard to turn down.
Over time, those projects piled up into real products. PetaRumah grew into a search engine with thousands of property listings. A furniture client needed a 3D room editor, so we built one from scratch in Three.js. Businesses kept asking for ERP systems they could actually stand to look at, so we made one they could whitelabel.
Now KLASTER is a small studio that handles the full stack — React, Node.js, Flutter, Three.js, PostgreSQL, the works. We're not a big agency with a sales team. We're developers who build things, and we're looking for more good people to build with.
