Zinc is a lightweight, full-text search engine designed as an alternative to Elasticsearch. It provides log search and analytics with significantly lower resource requirements.
Zinc features a web UI for management, REST API compatible with Elasticsearch's search syntax, and supports various data ingestion methods including bulk insert and fluentd/fluent-bit integration.
The search engine is written in Go and uses BlugeSearch as its indexing library. It runs as a single binary with embedded storage, requiring no external dependencies.
Common use cases include log aggregation, application search, and replacing Elasticsearch in resource-constrained environments.

Zinc is not a drop-in Elasticsearch replacement. While it supports similar query syntax, not all Elasticsearch features are implemented.
For high-availability deployments, additional architecture (load balancers, replication) must be implemented manually.
Memory usage scales with index size. Monitor resources for large deployments.
First admin credentials must be set via environment variables before first run.
