## What it is
Parca is an open-source continuous profiling server that collects, stores, and queries CPU, memory, and I/O profiles over time, down to the line number. It pairs with an eBPF-based agent that automatically discovers and profiles targets across infrastructure with near-zero instrumentation and low overhead.

## Use cases
- continuously profile CPU and memory usage in production
- find hot code paths to optimize and reduce infrastructure cost
- compare profiling data across deploys, versions, or regions
- investigate memory leaks and CPU spikes during incidents
- auto-discover and profile all workloads in a Kubernetes cluster
- store and query pprof profiles with a label-based query language

## When to choose
- you want always-on, zero-instrumentation profiling across C, C++, Rust, Go, Python, Ruby, PHP, Node.js, and more
- you run Kubernetes or systemd-based infrastructure and want automatic target discovery via eBPF
- you need to store, aggregate, and compare pprof profiles over time with a web UI and flame graphs
- you want a self-hosted, open-source alternative to commercial continuous profilers

## When to avoid
- you need tracing or distributed request-level observability rather than sampling profiles
- you cannot run privileged/root eBPF programs on your Linux hosts
- you need profiling on non-Linux platforms, since the eBPF agent is Linux-only
- you only need ad-hoc, one-off profiling of a single process

## Facets
