AboutAtlas Studio

We build software for the Windows desktop, in the open.

Atlas Studio makes Helm, Quartz and Mantle: open-source desktop software for Windows.

Three programs, each its own thing.

Each works on its own. On one desktop, they share a wallpaper and a theme, and pass status and links between them.

Atlas started as a task app.

The big AI companies now ship tools that do what it did, so instead of chasing them, we’re building something new.

The Atlas task app shut down on October 31, 2026, and the name carried over to the studio. The first three programs are Helm, Quartz and Mantle; their first Windows installers were published as version 0.1.1 on October 30, 2026.

If you used the Atlas task app, here’s what happened to it.

Everything happens in the open.

Every line is public.
All three live in public GitHub repositories under GPL-3.0.

What the code already does.

Say what went wrong.
A failure shows what happened and why, instead of failing quietly. Helm’s first run, for example, says why the SDK download failed and offers Try again.

Leave the machine as you found it.
A killed Mantle must leave Windows exactly as usable as before.

ReadMantle README, “Getting Windows back”
Your things stay yours.
Helm never signs you in and never sees your login. Mantle’s camera feature runs on your PC, and no frame is saved or sent.

Say the limits out loud.
Windows only, built and tested on one machine, unsigned installers for now. Each page says so where it matters.
