It replaces no other projects. Continuous profiling solves a different problem to Mimir, Cortex, and Tempo. Mimir and Cortex are for metrics, Tempo is for distributed tracing, Phlare is for collecting profiling samples over time.

Profiling is a layer below tracing and metrics in that it requires very minimal and generic instrumentation (of the runtime), while the others require specific instrumentation (of the application).

Profiles like CPU, heap allocs, goroutines, etc are collected on a continual basis, allowing you to see at any time how your application was making use of its runtime resources.
