About
BrownBox dev is a Ruby development shop with over a decade of experience building and maintaining production web applications.
Whether you need a new system built from scratch, an existing codebase extended, or an aging application brought back to health - it gets done. And it gets done in a way that won't haunt you a year later.
Equally at home in Rails or any other Ruby stack. Remote-first, based in Sweden, working with clients across Europe and beyond.
Open Source
We maintain several open-source Ruby gems, built out of real project needs and kept in active use:
Simple yet flexible role-based authorization for Ruby on Rails with comprehensive role management and multi-tenancy support.
Minimalistic cookie-based authentication for Ruby on Rails with granular session management, user impersonation, and support for multi-tenancy.
Fast parallel regex search across files powered by Ruby Ractors, available as a programmatic API and CLI.
Rails credentials access with blank value detection and clear human-readable error messages.
