About Kapsula

Kapsula lets you run self-contained HTML, JavaScript or TypeScript files as native mobile apps on Android and iPhone. You paste code or provide a URL, and it becomes a project with its own storage and notification channel. The app provides access to OS notifications that fire even when closed, local per-project storage, sound and vibration, all while running in a sandbox without any server or account requirement. Everything stays on your device.
