Logby

Logby is an open-source log management framework designed to unify the collection, processing, and querying of log data across distributed systems. It emphasizes structured logging, a modular pipeline, and pluggable back ends to support diverse environments, from on‑premises networks to cloud deployments.

The project provides input receivers for common formats such as JSON and syslog, a normalization stage to convert logs into a consistent schema, and a processing pipeline for enrichment and correlation. A scalable index and search layer enables fast querying, while retention and privacy policies help manage data lifecycles in compliance with organizational needs.

Logby originated in an international open-source community in the late 2010s with the goal of simplifying traditional log pipelines. The first stable releases introduced streaming ingestion, a domain-specific query language, and a pluggable storage backend. Since then, the project has evolved through multiple minor versions and community-driven extensions.

Deployment is possible on premises or in the cloud, with client libraries for several languages. It can integrate with existing observability stacks and supports multi-tenant configurations and role-based access control. The back end is typically a scalable store suitable for time-stamped data.

As of the mid-2020s, logby remains a niche option within the broader log-management ecosystem, maintained by an active but comparatively small community. Documentation and code are hosted in its public repository.
