makandra is a Rails consultancy based in Germany. Since 2009, it has delivered over 200 custom web applications across the full software lifecycle — from requirements and UI/UX to development, operations, and maintenance. Clients range from small businesses to global enterprises. Notable projects include Siemens SiESTA (cybersecurity testing), JustClaims (air passenger claims), Audi MediaCenter (press hub), GREENZERO (LCA platform), JUUUPORT (online youth counseling), and Studyflix (video learning platform).
makandra often maintains applications long-term — some since 2010 are still in active use. From this commitment emerged Rails LTS, a service providing security patches for legacy Rails versions, compatible with modern Ruby. On the infrastructure side, a dedicated DevOps team hosts and manages Rails apps on makandra-owned hardware in a German data center.
Around 95% of customer applications developed by makandra are built using Ruby on Rails.
Most makandra applications follow a monolithic architecture with heavy namespacing, using mostly RSpec and capybara-lockstep for testing and PostgreSQL as the default database. Frontend development prioritizes progressive enhancement with Unpoly, though React and Angular are used when needed. Deployments rely on Linux VMs with Capistrano, leveraging OpsComplete, their in-house hosting platform, provides Rails-specific automation for provisioning and deployment.
In addition, makandra maintains a significant number of internal Rails applications that support daily operations — including tools for CVE tracking, project management, billing, hot desking, lunch booking, secret sharing, knowledge management, private LLM chat, and more.
In 2024, Company became a contributing member of the Rails Foundation.
Joining the Rails Foundation was a huge milestone for us and shows that we are fully behind Ruby on Rails. We are proud to be part of this community and we are determined to do our part to further develop and strengthen the framework.
