CaptainCasa presents RapidApp, a new low-code tool that takes a deliberately different approach from traditional low-code platforms. RapidApp is the result of many years of enterprise development experience and combines fast modelling with the full flexibility of a professional software architecture.
Instead of “clicking together” complex applications visually, RapidApp follows the principle:
“Configure the default. Code the unique.”
Everything that is standardisable—data model, tables, maintenance screens, user workplace, authorization concept, REST API—is generated automatically. Everything that makes an application unique is added in Java: individual UI components, complex logic, integrations and processing steps.
This combination solves a well-known issue of many low-code projects:
Traditional platforms accelerate the creation of simple applications but reach architectural and functional limits as complexity grows.
RapidApp does not encounter these limits.
Because the entire platform is Java-based, it remains fully extensible, integration-capable and maintainable over the long term—without technological gaps or mixed architectures.
RapidApp therefore brings together two worlds:
A fast start and high productivity through automatic generation of core application components
Maximum flexibility through individually extendable components in a single programming language (Java)
Companies gain a tool suitable for both rapid results and sustainable, complex enterprise applications. RapidApp runs on an independent Java runtime, making it easy to deploy (e.g. via Docker) and seamlessly integrable into existing IT landscapes.
With RapidApp, CaptainCasa brings the low-code concept into the reality of demanding enterprise IT:
Built in minutes. Ready for years. This is RapidApp.
