What are Coroot and Cortex?
Coroot
Coroot is an open-source observability tool that uses eBPF to gather metrics, logs, traces, and profiles with zero instrumentation. It automatically surfaces service maps, SLOs, and root-cause insights.
- eBPF zero-instrumentation telemetry
- Automatic service maps
- Built-in SLO tracking
- Root-cause analysis
Cortex
Cortex provides a horizontally scalable, highly available, multi-tenant, long-term store for Prometheus metrics. It offers a single API endpoint for querying and writing time series data across clusters.
- Multi-tenant metrics storage
- Horizontally scalable
- Prometheus-compatible API
- Long-term retention
Coroot vs Cortex: key differences
Both projects are written in Go. Cortex is the more established project (first released 2016), while Coroot arrived in 2022.
