About MARZ

MARZ (Memory Adaptive Runtime Zone) is an open-source Spring Boot library that enables true runtime configuration hot-swap at the JVM level. It was born from frustration with the existing options — rolling restarts that take 15-45 minutes, @RefreshScope that rebuilds entire bean contexts, and feature flag services that cost $20K–$120K per year.

The core idea is simple: annotate a field with @Marz, point it at a config file, and the value updates live when you edit the file. No restart. No proxy. No external infrastructure. Just a volatile write that takes ~50ms.

Open source first

The annotation library is free and open source under the Apache 2.0 license. Read the code, submit issues, contribute PRs. That's how developer tools should work.

The platform

For teams that need centralized visibility and control across multiple application instances, the MARZ Platform provides a web dashboard with RBAC, audit logging, and real-time WebSocket propagation. This is the commercial product that funds the open-source work.
