Kunkun review
A cross-platform launcher built for developers who want to create or install JavaScript extensions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Kunkun is an open-source application launcher for macOS, Windows, and Linux, aimed at people who want to extend a launcher with JavaScript rather than rely only on built-in commands. Developers can create extensions with template UI, headless, or custom UI commands, while people who prefer installing existing tools can discover them in an extension store. This cross-platform approach makes Kunkun a fit for extension developers working across desktop operating systems, as well as users comfortable choosing or creating extensions for their workflows.
Its extension model is the main point of distinction. Extensions can be installed from the store or from GitHub, npm, and tarball files. Documented APIs cover opening files and folders, file-system access, and opening URLs, alongside controlled shell-command and script execution. Permission declarations define extension capabilities, including access relevant to shell commands. That gives developers a way to describe what an extension can do, but it also means users should consider those declared capabilities when choosing extensions. The launcher’s flexibility is tied to its extension ecosystem and JavaScript development, rather than a promise that every workflow is available out of the box.
Kunkun makes sense for developers who want to build, share, or install launcher extensions across macOS, Windows, and Linux, especially when custom commands or UI matter. It is less suitable for someone seeking a launcher whose value depends on a broad set of built-in tools without extension work. The documented file-search scenario is an extension use case, while shell and file operations are exposed through APIs for extensions. Buyers should therefore evaluate the extensions they plan to use—or be ready to create one—before choosing it as the center of their launcher workflow.
