Zero-Setup OpenTelemetry: Lightweight Single-Binary Tracing for Developers

Developers testing OpenTelemetry instrumentation have traditionally needed heavy infrastructure like Jaeger or full collector stacks, but otel-front eliminates this friction with a zero-setup single binary. Supporting traces, logs, and metrics in a lightweight package, it makes observability testing as simple as one command with no configuration. This reflects a broader shift in the observability space toward reducing developer friction and making advanced tooling accessible without DevOps expertise.
