Independent Creative Studio

We make what we want to use every day.

Vast Logic is an independent creative studio. After years of building products at leading tech companies, we set out to make things of our own: simple but powerful, and cared for down to the last detail.

Beautiful. Useful. Made to last.

Most products settle for two. We hold out for all three.

Beautiful

A pleasure to look at and to hold. Type, space, and motion, done with enough care that nothing needs forgiving.

Useful

It does the one thing you opened it for, quickly, with as few steps as we can honestly manage. Practical over clever.

Made to last

Solid underneath, kept in good repair. Still worth opening years from now, not a year of polish and then silence.

What we do

iOS, macOS & tvOS apps

We build native apps for Apple platforms, with attention to performance, platform conventions, and detail.

Web applications & tools

Fast and lightweight things for the browser: practical, focused, and out of the way.

Developer utilities & automation

We create utilities and automation that remove friction from everyday development workflows.

Products

MoonMark

A native Markdown reader for Mac

Built for reviewing the docs your AI agents write. Plans and designs open as finished documents, with an outline on the left and room for tables, code, and diagrams. Switch to the source to make an edit, and when the agent rewrites the file, the window keeps up.

In beta

Dimma Screen

Lock your Mac, keep the screen on

A menu bar app for macOS. Step away and it covers every display with a tint you can barely see. Your desktop stays lit and keeps moving, so it looks like you'll be right back. Touch a key or the mouse, and it asks for your PIN.

About

Vast Logic was founded by engineers who spent many years at leading tech companies, shipping products used by millions of people.

We started Vast Logic to build differently: a focused studio with high standards, making things good enough that we reach for them ourselves, every day. Everything we release gets full attention, from architecture to the last pixel.

We believe good design is quiet: it respects your time, your privacy, and your device.
