Vector

Vector is the observability pipeline that makes Fluentd and Logstash feel like relics. Written in Rust, it handles logs and metrics with 5-10x better throughput, half the memory, and a type-safe transformation language (VRL) that catches errors at compile time instead of in production at 3am.

If you're shipping logs in a cloud-native stack, Vector should be your first choice. It replaces Fluentd (CNCF standard but slow, Ruby-based) and Logstash (Java, heavy, Elastic-coupled) while being genuinely easier to configure. Fluent Bit is the lightweight alternative, but Vector beats it 2x on heavy workloads. Datadog and Splunk are the commercial options you're probably trying to escape.

The catch: Vector is MPL-2.0 licensed and backed by Datadog (who acquired Timber/Vector). The CNCF crowd may prefer Fluent Bit for vendor neutrality. And if your entire stack is Elastic, Logstash's native integration is hard to replicate.
