Hitomi aims to help you gain insight into structured, and possibly massive data. Its unique schema system allows modeling domain-specific data in non-standard formats with ease. For instance, it can be configured to load logcat journals from Android, with a schema describing the grammar of the file.
Hitomi is developed completely with Flutter/Dart. It handles millions of records effortlessly, showing the potential of pure Dart/Flutter in serious business and productivity applications. By contrast, most of the applications of this type tend to take a hybrid approach, employing different languages for the UI and more demanding tasks.
Hitomi is still in the very early stage of development. It is not yet ready to be used in production. We appreciate any kind suggestions and feedback!
