# Why eBPF

> Understanding why Tracer uses eBPF for observability

Traditional approaches rely on logs, metrics exporters, or code instrumentation.<br />
With eBPF, Tracer:

**See everything**<br />System calls, process lifecycle, I/O, and scheduling events

**Stay lightweight**<br />Sampling at kernel level without copying large data

**Stay safe**<br />Verified, sandboxed bytecode that cannot crash your node

**Stay universal**<br />Works with any container, binary, or programming language

The result: zero-overhead visibility into black-box tools, a critical advantage for bioinformatics and computational biology pipelines.
