Show HN: Perfetto2LLM - A tool to pass system traces to an LLM
ak2242 Wednesday, December 31, 2025
I work with perfetto traces for ML/GPU optimization a lot. Copy pasting trace info to LLM is not easy. As usually the traces are gzip compressed, have very large file sizes. Also there is no way to select a certain section and sending it to LLM easily (can maybe write a query to do this but not ergonomic). So vibe coded this tool to quickly select the kernels/slices/threads I want to ask about and one click to get a text/json/markdown in my clipboard to paste for LLMs.
I think an MCP server for this might also be useful (tried a few but all miss certain things i wanted so chose to just build this quickly)
Summary
The article discusses Perfetto, an open-source tracing framework that allows developers to analyze system performance and identify bottlenecks. It highlights Perfetto's key features, including its ability to capture data from various sources and its integration with machine learning language models for enhanced analysis.
