The development companythat ships its own products.
XICO is an AI and software development company in Guangzhou. We build and operate Xico Clean and Machi, and take on client work in AI applications and custom software — delivered to the same standard as our own products.
Built by us. Maintained for years.
Xico Clean and Machi are built and operated by XICO. If you are evaluating us for a project, start by trying them.
Xico Clean
Make your Mac fast and clean again
A native Swift-built Mac cleaner: Smart Scan, developer junk, space visualization, duplicate files and privacy cleanup — all local, previewable and undoable.
Machi
Life in Japan — one app is enough
A one-stop platform for students, workers, and newcomers in Japan: city guides, housing, jobs, a second-hand market, and local community.
Game development
Games are next
We are bringing our native engineering, graphics, and interaction experience into games. Partnership enquiries are welcome.
One set of capabilities, for products and projects
Each of these runs in our own products first, then goes into client work.
AI Application Development
LLM applications, knowledge bases, and automated workflows — from solution design through development to evaluation. Xico Clean's smart scanning and image recognition test this capability daily.
Native Apple Platforms
macOS and iOS development in Swift 6 + SwiftUI: deep system integration, performance work, Universal distribution, and completed Apple notarization. We take our own products through each step.
Web & Mobile
Multi-platform development with Next.js, iOS, and Android, covering admin consoles, payments, and internationalization. Machi and this site run on this stack.
Delivery & Maintenance
Deployment, monitoring, data safety, and a steady release rhythm. After launch we stay responsible — no drop-and-run delivery.
The rules we build by
These principles come from building products daily, and they govern every project we deliver.
Define the problem first
Before any code: confirm the goal, the users, and the boundaries. Clear scope is what makes timelines and budgets honest.
Details make the quality
Interfaces, copy, error states, loading speed — users feel all of it. We don't let these slide.
Data safety is a precondition
What can be processed locally stays local, and client data has explicit permission boundaries. This is not negotiable.
Responsible after launch
Our products keep getting updates; client projects get long-term maintenance. We are not a team that disappears after handover.
From first conversation to launch and maintenance
Our own products go through the same process. Every step has a concrete output.
- 01
Talk and assess
Understand the background, goals, and constraints; judge the scope and technical route; give honest advice.
- 02
Plan and prototype
Information architecture, interactive prototypes, and the technical plan come first, so risks surface before the build.
- 03
Build and review
Work proceeds in versions with transparent progress, and every stage has a reviewable result.
- 04
Launch and maintain
Deployment, monitoring, fixes, and iteration. Maintenance is part of the plan from the start.
Good software is worth real effort.
Our products and client projects share one standard: clear structure, solid performance, and long-term maintainability. That is what makes software hold up over time.
AI is changing how software is built and what it can be. We put it to work on real problems — in our own products first, and for clients once it has proven itself.
