Software house & digital agency · Yogyakarta, Indonesia

Websites, apps, and AI automation.
Built for businesses that want to grow.

Using is a software house in Yogyakarta, Indonesia. We design and build websites, custom software, and AI automation that your customers can find and your team actually uses.

We design it.

01 / Design

Every project starts with a business question, not a moodboard. We map who uses the product, what they need to do, and which screens and pages make or save money.

  • 01User flows and a sitemap before any pixels
  • 02Clickable wireframes in the first week
  • 03A design system your team can reuse

We build it.

02 / Build

Designers and engineers on one team, in one conversation. Websites, web and mobile apps, and business systems are built on Next.js, Supabase, and TypeScript, in code your own team can read and extend.

We automate it.

03 / Automate

Once the system runs, we connect it to the work around it: AI assistants that answer customers, documents that file themselves, reports that arrive before anyone asks. Then we look at the numbers with you.

  • 02Documents and orders that file themselves
  • 03Reports that arrive before anyone asks

Full disclosure

We take on a few clients at a time, so every project is handled by the same senior engineers and designers from kickoff to launch. If what you need is outside our expertise, we will tell you on the first call.

05 / Frequently asked

What does Using do?

Using is a software house and digital agency in Yogyakarta, Indonesia. We design and build websites, web and mobile apps, business systems such as POS and HRIS, and AI automation for growing businesses.

Who do you work with?

Small and medium businesses, startups, clinics, schools, and agencies across Indonesia and Southeast Asia that have a real product or service and want software that matches its quality. We work remotely and meet in person in Yogyakarta and Jakarta.

How much does a project cost?

Every project has a fixed price agreed before kickoff, based on a written scope. Websites usually take weeks, custom systems and apps take months. There is no hourly billing and no cost that appears halfway through.

Can you add AI to a system we already have?

Yes. Most of our AI automation work connects to existing tools: WhatsApp, email, spreadsheets, accounting software, or an in-house database. We start with one workflow, measure the time it saves, then expand.

Do we own the code?

Yes. Everything we make for you, from design files to the repository and the accounts it runs on, is handed over in full when the project ends.

Can you work with our in-house team?

Yes. We often work alongside founders, marketers, and internal engineers, leading design and architecture while fitting into how your team already ships.
