kolaydr

kolaydr is an open-source software project that provides a lightweight framework for building and connecting microservices, data pipelines, and event-driven applications. The project aims to simplify deployment and orchestration by providing a declarative configuration model and a set of pluggable components for routing, transformation, and observability. The name combines "kolay" (Turkish for easy) with a suffix intended to suggest routing and data streams.

Design and architecture: It uses a modular architecture with core runtime, connectors, and processing plugins. It supports declarative routing rules, retry and backoff policies, message deduplication, and built-in metrics. It can run in containers and integrates with Kubernetes and cloud-native tooling.

Development and history: kolaydr appeared in the open-source ecosystem in the early 2020s as a community-driven project. It has an active community on GitHub, with releases, issue tracker, and documentation. Governance is through a contributor-license and maintainer teams.

Usage and reception: It is used by small and mid-sized teams to connect services and data sources. Critics note that while it reduces boilerplate, performance can vary depending on workload and plugin choice; users emphasize evaluating benchmarks before large deployments. Advantages include ease of use and extensibility.
