Our Software
We build software focused on developer productivity and database tooling. Below is an overview of what we are currently developing.
Tentacle is a tool for exploring and visualizing database schemas. The tool is designed to help developers quickly understand the structure of complex databases — whether they are working with a legacy system, onboarding to a new codebase, or designing a new data model.
Import database schemas directly from SQL files to get an immediate visual overview of your database structure.
Work with Database Markup Language (DBML) files for a modern, human-readable schema definition format.
Navigate tables, columns, and relationships through an interactive visual interface designed for clarity.
See how tables relate to each other at a glance, making it easier to understand complex data models.
Designed specifically for engineers and developers who regularly work with database schemas and data structures.
Working with large or unfamiliar database schemas can be time-consuming and error-prone. Tentacle addresses this by providing a visual, interactive environment where developers can quickly orient themselves, trace relationships, and understand the overall architecture of a database without having to read through hundreds of lines of SQL.
The application is currently under active development. It is planned for release on macOS through the Apple ecosystem.
Tentacle is the first in a series of developer tools planned under the Arnstad Holding brand. We are focused on building applications that make complex technical structures easier to understand and work with. Additional tools and products may be released in the future.
