go-kit/kit

This system is a modular Go toolkit for building microservices, providing a standardized way to implement authentication, authorization, and observability across various transport protocols. It offers a unified interface for logging, metrics, and distributed tracing, with built-in support for HTTP, gRPC, and message brokers like RabbitMQ and NATS. Additionally, it includes service discovery mechanisms for registries such as Consul, etcd, and ZooKeeper, enabling resilient client-side load balancing and endpoint management.

How it got here

2015–2016 · distributed systems primitives and service discovery

This period focused on establishing a comprehensive set of distributed systems primitives, including robust service discovery implementations for Consul, ZooKeeper, and Eureka, alongside a new endpoint and transport abstraction layer. The team also expanded the metrics and tracing capabilities to support multiple backends and distributed tracing standards, while refactoring the logging infrastructure to a standalone repository.

2017–2020 · Transport and backend expansion

This period focused on expanding the library's capabilities by adding support for diverse transport protocols (gRPC, NATS, AMQP, AWS Lambda) and logging backends (syslog, logrus, Zap). It also introduced new metrics exporters for CloudWatch and InfluxData, alongside service discovery implementations for etcd and internal caching mechanisms.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 20 July 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 78fbbceece — the exact code this score is about.
  • Scored under rubric rubric-2026.08.17. Score the same commit under that rubric and you get the same number.
