One job, done well
Each product solves a single, specific annoyance. If it needs a manual, it's doing too much.
A small software studio · since 2024
Practical software,
built small.
We make native tools that do one job, launch instantly and get out of the way. No accounts to create, no dashboards to log into — just the thing you needed, on your machine.

AI Usage Bar
Every AI quota you pay for, in your menu bar.
If you juggle Claude, ChatGPT and GLM subscriptions, you know the routine: open a tab, find the usage page, do the maths on when the limit resets. AI Usage Bar does it for you. A ring in the status bar shows how much of your current session is left; one click shows every account, both windows, and the time until each one resets.
- All providers, side by side. Claude (5-hour and weekly), ChatGPT/Codex (session and weekly) and GLM on z.ai.
- As many accounts as you have. Personal and work, Pro and Max — mute any of them from the status bar.
- Native and light. AppKit + SwiftUI, around 30 MB of memory, refreshes every five minutes.
- No sign-up. Paste a session once per account and the app checks each provider directly.

How we build
Three rules we don't break.
Native, not wrapped
Swift on the Mac, Kotlin on the JVM. Small binaries, low memory, instant launch, nothing running that doesn't have to.
Used by us first
Everything we ship ran on our own machines for weeks before it got a download button. We build what we needed and couldn't find.
In the workshop
What's coming next.
Tools we use every day that are on their way to becoming products.
- Mac Monitor Control usable today Turn a MacBook's built-in display off while an external monitor stays on, so the lid can stay open for airflow. A one-second watchdog brings the screen back if the cable goes.
- SpringBuddy in development Spring Boot essentials for IntelliJ IDEA Community Edition — run configurations, bean navigation and config assistance that normally need Ultimate.
- HeyCast in development A fast, keyboard-first launcher for macOS: fuzzy app search, calculator, clipboard history, window tiling, and an AI inbox that answers while you keep working.
About
A studio of one, for now.
Founded in 2024, phucngu is run by Phuc Nguyen, a backend engineer from Vietnam. Days go to Java, Kotlin, Spring, Postgres and Kubernetes; evenings go to building the small tools those days are missing.
We stay small on purpose. It means every product gets attention from the person who wrote it, bug reports get read by a human, and nothing ships that we wouldn't use ourselves.
Got a problem worth a small tool?
Feature requests, bug reports, or an idea you'd like built — we'd like to hear it.
