## What it is
SigLens is an open-source observability platform providing log management, metrics, and tracing in a single Go binary with zero external dependencies, positioned as a 100x more efficient alternative to Splunk. The project has been officially archived and is now read-only under the Apache 2.0 license.

## Use cases
- replace splunk to cut observability costs
- search and analyze application logs
- collect logs metrics and traces in one tool
- self-host a lightweight log management system
- ingest opentelemetry telemetry data
- query logs fast without elasticsearch cluster overhead

## When to choose
- you want a single-binary self-hosted alternative to Splunk or Elasticsearch for logs
- you need logs, metrics, and traces without managing multiple backends
- you want to fork a permissively licensed observability codebase

## When to avoid
- you need active maintenance, updates, or vendor support - the project is archived
- you require a guaranteed long-term roadmap or community fixes
- you need a managed cloud observability service
