Widescope
Browser-native trace viewer for LLM and AI agent pipelines
About project
Widescope is a browser-native trace viewer for LLM and AI agent pipelines, powered by Rust compiled to WebAssembly. It runs entirely in the browser : no backend, no installation, no data leaves your machine.
Open a trace JSON file and get instant waterfall visualizations, span timelines, token usage breakdowns, and agent step inspection. Built for AI engineers who need to debug LLM agent traces without setting up a full observability stack.
