About Callulu and CSS Box-Shadow Code Generator

In their own words, as submitted to SaaSHub.

Callulu
CSS Box-Shadow Code Generator

Callulu is a macOS menu bar app that puts one of eight visual cues on screen: a flash to start, a dimming of everything but the center of the screen, a light that passes along one edge at an interval you choose, a lit ember at the edge, a water surface, a still eye, a breathing guide, and a slow...

Features and specs

What each product offers, as listed by its team.

Callulu 3 features
CSS Box-Shadow Code Generator 5 features
  • Eight visual cues
    A flash to start, a focus dimming, an interval light, an ember, a water surface, an eye, a breathing guide, and a slow softening to end the day.
  • Each cue has one job
    LIGHTNING to begin, SHADE to focus, WISP to pause, EMBER to feel safe, UNDINE to regain composure, LULL to step back, SYLPH to reset, LUNA to finish. The menu shows each job under the cue's name.
  • Runs from Shortcuts and the terminal
    Any cue can be started through a callulu:// link, so Shortcuts, Raycast, Alfred or one line in Terminal can run one.
  • Visual real-time preview
    The generator provides an instant visual preview of the box-shadow effect as you adjust the parameters, allowing users to see exactly how their shadow will look before copying the code.
  • Simple and intuitive interface
    The tool has a clean, straightforward interface with sliders and input fields that make it easy for beginners and experienced developers alike to create box-shadow effects without memorizing CSS syntax.
  • Free and browser-based
    The tool is completely free to use and runs entirely in the browser with no installation, sign-up, or downloads required, making it instantly accessible to anyone.
  • Quick code output
    The generator produces ready-to-use CSS box-shadow code that can be copied and pasted directly into a stylesheet, saving development time and reducing syntax errors.
  • Adjustable parameters
    Users can easily tweak key shadow properties such as horizontal offset, vertical offset, blur radius, spread radius, and color to fine-tune the exact shadow effect they need.

Possible disadvantages

  • Limited to single shadow
    The tool appears to only support generating a single box-shadow value at a time, whereas CSS allows multiple comma-separated shadows for more complex effects.
  • Minimal styling options
    The generator focuses solely on box-shadow and doesn't include related CSS properties like border-radius or background color adjustments that could help users visualize the shadow in a more realistic context.
  • No preset examples
    The tool lacks a library of pre-built shadow presets or templates that users could use as starting points, which would speed up the design process for common shadow styles.
  • Basic UI design
    The interface is quite minimal and could benefit from a more polished, modern design with better visual hierarchy and additional guidance or tooltips for less experienced users.
  • No export or save functionality
    There is no built-in way to save, bookmark, or export multiple shadow configurations for later comparison or use, so users must manually copy and store their generated values elsewhere.

Questions & Answers

As answered by people managing Callulu and CSS Box-Shadow Code Generator.

How would you describe the primary audience of your product?

Callulu's answer

People who spend long stretches alone at a Mac and want something on the screen to mark the parts of the day: getting started, settling into a task, stepping back, and stopping at a reasonable hour.

It also suits people on older hardware, since it runs on macOS 13 and on Intel as well as Apple silicon.

One caution: the opening cue is a brief flash across the whole screen, and several cues change display brightness. Anyone sensitive to flashing light should leave that cue switched off.

What makes your product unique?

Callulu's answer

LIGHTNING starts the work, SHADE is for focus, LUNA closes the day, and five more sit in between. You pick a cue, and it shows on the screen for a moment or for as long as you leave it on.

Drawing a cue needs no Accessibility or Input Monitoring permission. Settings stay on the Mac.

Why should a person choose your product over its competitors?

Callulu's answer

Choose it if you want a cue on the screen rather than a timer. Dimming tools hold one state over the screen for as long as they run, and timer apps count sessions. Callulu has eight cues for different moments of a workday, and you turn each one on when you need it.

It runs on macOS 13 and later, on Apple silicon and Intel. Cues can be started from Shortcuts, Raycast or a terminal command through a callulu:// link. The direct download is $14.99 once and adds keyboard shortcuts; the Mac App Store edition is free for 14 days, then $3.99 once.

If you want blocking or time tracking, one of its competitors will serve you better.

What's the story behind your product?

Callulu's answer

Before I knew it, I could no longer control myself, and each time it happened I felt regret and a sense of inferiority.

"Lately, this might be getting a little out of hand."

A small worry like that is why I decided to make an app for staying myself.

Callulu came out as a direct download on 3 September 2026. The Mac App Store edition followed ten days later, on 13 September.
