Transparency & Blur

Chau7 lets you see through your terminal to the app behind it. With blur, so it stays readable.

The problem

  • Floating terminals should feel native on macOS, not like opaque rectangles pasted over your desktop.
  • Transparency without blur often hurts readability instead of helping it.

What Chau7 does about it

  • Overlay appearance supports adjustable opacity for the terminal window.
  • Blur and material-style compositing keep content readable over busy backgrounds.
  • Works naturally with the dedicated overlay window mode.
  • Appearance settings let you tune atmosphere without sacrificing text contrast.

What is Transparency & Blur in Chau7?

Transparency & Blur is a feature in the Chau7 terminal that lets developers adjust window opacity per profile and apply a native macOS vibrancy blur behind the transparent background.

Chau7 uses window-level opacity (window.alphaValue), which means both text and background become semi-transparent together. The vibrancy blur effect helps maintain readability by diffusing the content behind the window. At moderate transparency levels, terminal output remains legible.

How to enable terminal transparency on macOS with Chau7

In Chau7, open a profile's settings and drag the opacity slider. Chau7 previews the transparency change in real time as you adjust the slider, from fully opaque to heavily transparent.

Background blur activates automatically when transparency is enabled. Chau7 uses the native macOS compositor for the blur effect, creating a frosted glass appearance that lets you see underlying content without it competing with terminal text.

Does Chau7's transparency affect text readability?

Chau7 uses window-level opacity, which means both text and background become semi-transparent together. At moderate transparency levels (70-100%), text remains easily readable.

The native macOS vibrancy blur effect diffuses background content, helping maintain readability even at lower opacity values. Chau7's transparency respects the current theme colors, meaning dark and light themes both produce a natural layered appearance.

How does Chau7's transparency & blur compare to other terminals?

Most terminals offer basic transparency but lack background blur. Without blur, transparent terminals produce an unreadable mess of overlapping text and images.

iTerm2 offers transparency but does not use native macOS vibrancy blur. Alacritty supports opacity but has no blur on macOS. Hyper supports transparency with limited blur options.

Chau7 combines adjustable per-profile opacity with native macOS vibrancy blur. The blur runs on the GPU compositor with no frame rate impact, and each profile stores its own opacity value so developers can mix opaque and transparent terminals.

Is there a performance impact from Chau7's transparency and blur?

No. Chau7's blur effect uses the native macOS compositor, which runs on the GPU with negligible performance cost. There is no frame rate impact during normal terminal use.

Per-profile opacity means developers can keep their primary coding profile fully opaque for focus while setting a monitoring or logs profile to semi-transparent for desktop awareness. Switching between profiles in Chau7 applies the opacity change instantly.
