Xtrace, a Unix-style command-line profiling tool for macOS, leveraging Instruments for CPU, GPU, and Memory analysis.

Technical Positioning
A terminal-first profiling workflow for macOS developers, eliminating the need to constantly switch to the Instruments GUI.
SaaS Insight & Market Implications
Xtrace addresses a significant developer pain point for macOS engineers: the inefficiency of GUI-centric performance analysis tools. By providing a terminal-first interface to Instruments, it streamlines profiling workflows, enabling faster iteration and integration into automated pipelines. The JSON output for 'automation/LLM workflows' is a forward-looking feature, indicating a trend towards programmatic and AI-assisted performance optimization. This tool caters to a specific, high-value segment of developers who demand granular control and scriptability in their debugging processes. Its macOS-only nature and reliance on Instruments limit its broader market, but within its niche, it offers a compelling efficiency gain, potentially reducing development cycles and improving application performance.

Show HN: Xtrace – Unix-Style macOS Profiling for Instruments (CPU/GPU/Memory)

I built this because I wanted a terminal-first profiling workflow on macOS, without constantly switching into the Instruments GUI.What it does today:- CPU analysis: summary, timeline, calltree, collapsed stacks, flamegraph, diff- GPU analysis (trace-gpu.py): active/idle ratios, command-buffer cadence, process ownership- Memory analysis (trace-memory.py): summary, leaks, growth, heap/regions- Recording modes: launch, attach by PID/name, wait-for spawn, system-wide- Root-aware attach flow for protected/root-owned processes- JSON output for automation/LLM workflows (I use it in autoresearch loops: hypothesis → experiment → keep/discard)Other notes:- macOS only (Instruments/xctrace)- core analysis is Python stdlib (no pip deps)- optional tools: speedscope + inferno for best visualizationWould love feedback on workflow, rough edges, and what integrations would make this more useful.
