One clear job
Quartz apps start with a specific workflow rather than a plan to become an all-purpose suite.
About Quartz
Small Mac tools, built with a clear point of view.
Quartz is an independent macOS software studio founded by Peng Liu. It builds focused utilities that keep workflows understandable, data local wherever practical, and ownership simple.
The studio
Quartz exists to make the kind of Mac software that can explain what it does, stay out of the way when it is not needed, and keep ownership of app features simple.

The founder
Who designs and develops Quartz software.
Peng Liu is the founder and macOS software developer behind Quartz. He designs and develops Tuck, Facet, PeekMark, DiskSteward, Quartz Probe, and Lemvia, working across native Mac interface design, local-first workflows, developer tooling, licensing, distribution, and product support.
Principles
The product decisions shared across the Quartz portfolio.
Local where practical
Documents, scans, histories, diagnostics, and workspace data stay on the Mac wherever the product can do the work locally.
Own the app
App upgrades use one-time purchases; subscriptions are reserved for optional ongoing services such as managed cloud translation.
Explain the impact
Tools that change files, storage, settings, or network state should make the consequence visible before the action.
Native Mac design
Quartz software is designed for macOS conventions, keyboard workflows, desktop context, and the way people actually use a Mac.
