Iii
iii is an open-source tool designed to help developers compose, extend, and observe services in real-time. It provides a unified approach to managing microservices and distributed systems by enabling dynamic composition and extension of service functionalities. The tool focuses on real-time observation, allowing teams to monitor service interactions, performance, and behavior as they occur. This capability is particularly useful for debugging and understanding complex service meshes. iii is distributed as a free, self-hosted solution and can be integrated into existing development workflows. Its goal is to simplify the complexity of building and maintaining modern service-oriented architectures.
