What is eprofiler-tui?

eprofiler-tui is a Rust TUI that receives OTLP/gRPC profiles from eBPF tools like opentelemetry-ebpf-profiler and renders live icicle flamegraphs in your terminal. Run `cargo install --git https://github.com/rogercoll/eprofiler-tui` then `eprofiler-tui --port 4317`, point your async profiler ebpf or otelcol ebpf profiler at localhost:4317, and get interactive hotspot views with thread grouping by name. It solves jumping between CLI profilers and web UIs for quick eBPF debugging.

Why is it gaining traction?

Live updates with freeze toggle let you pause for smooth vim-style nav (hjkl depth/sibling, Enter zoom, / fuzzy thread search), plus frame tags like [Native]/[Kernel]/[JVM]. Pairs seamlessly with aya ebpf github, bcc ebpf github, cilium ebpf github, or elastic ebpf profiler—no exporters or Grafana needed for terminal-first viz. Devs in ebpf examples github and rust ebpf github love the zero-setup hook for prod Kubernetes flames.

Who should use this?

SREs tracing opentelemetry ebpf profiler kubernetes services, kernel hackers using hotel ebpf profiler or learning ebpf github, systems devs verifying ebpf verifier github programs. Ideal for opentelemetry ebpf profiler grafana alternatives when you want instant terminal feedback without dashboards.

Verdict

Worth cargo installing for eBPF profiler github workflows if you're already piping OTLP profiles—features deliver now. But 46 stars and 1.0% credibility mean it's pre-1.0 alpha; solid README but light tests/docs, so test in non-prod first.
