Compare current Shimeji runners with Paw-Paw, a native macOS 13+ desktop pet that reacts as you type.
Disclosure: Shimeji is a community ecosystem rather than one current commercial product. Paw-Paw is not affiliated with Group Finity, Shimeji-ee, Shijima-Qt, or their maintainers. We reviewed public project pages and did not benchmark every runner.
Classic Shimeji-ee was built around Java and primarily targets Windows. Mac users now have community alternatives: Shijima-Qt is a no-Java open-source beta, while ShimejiEE-cross-platform offers a Mac build with a bundled runtime. Each runner has different compatibility and Gatekeeper caveats.
Runtime choice — classic Shimeji-ee requires Java. macOS no longer bundles Apple's legacy Java runtime, so use a compatible third-party runtime or a package that includes one.
Beta caveats — Shijima-Qt's current desktop release is v0.1.0 from March 2025. Its official itch page documents current macOS reports, and the developer says the Qt build is awaiting a rewrite.
Different surfaces — browser extensions keep characters inside the browser. Desktop runners can roam outside it, but must be compatible with your macOS version and may trigger Gatekeeper warnings.
No universal performance answer — resource use varies with the runner, character pack, number of characters, animation, and Mac. We did not benchmark these projects.
Paw-Paw is built in Swift for macOS 13 or later. It needs no separate Java runtime, Electron app, or browser extension. Unlike a roaming Shimeji runner, Paw-Paw stays in a selected screen position and reacts to typing and clicking.
Instead of importing custom shimejis, Paw-Paw comes with a cast of illustrated animals — bears, foxes, shibas, capybaras, raccoons, and more. Custom character imports are not currently supported.

| Built-in characters | Aims for Shimeji-ee pack compatibility; individual packs may vary | A whole cast included |
| Cosmetics/hats | Character-pack dependent | Collectible hats |

Unlike independently roaming Shimeji characters, Paw-Paw responds to typing and clicking. The animal types when you type, reacts to clicks, and falls asleep when you take a break.
As you work, you earn random hat drops in every rarity, from common to legendary. There are collectible hats to earn — from tiny sprout hats to ramen bowls. Drag them onto your pet to dress them up.
Paw-Paw can be kept open while studying or writing. Whether animation feels cozy or distracting is personal; close it whenever it pulls attention away from the task.
Classic Shimeji-ee primarily targets Windows and requires Java. On Mac today, Shijima-Qt offers a no-Java beta, while ShimejiEE-cross-platform provides a Mac build with a bundled runtime. Compatibility depends on the runner, pack, and macOS version.
Choose Shijima-Qt if importing Shimeji packs and roaming movement matter most. Choose Paw-Paw if you want a native macOS 13+ pet that reacts to typing and includes built-in animals and hats.
No separate Java runtime, Electron app, or browser extension is required. Paw-Paw is a native Swift app for macOS 13 or later.
