It receives trace data from your application, stores it on your machine, and gives you a real-time dashboard to monitor and debug every LLM call, tool invocation, and chain execution. No cloud account is required and no data leaves your environment. --- Features Overview - shows your OTLP endpoint and integration snippets the moment Axon starts Trace Views Transcript — renders the run as a conversation with tool call inputs and outputs inline Waterfall — each span as a horizontal bar on a shared time axis with a detail panel Tree — parent-child span hierarchy with type icons, model names, and token counts Raw — full JSON of every span with a copy button --- How it works Axon runs entirely on your machine. When you start it, a single server comes up that handles two responsibilities: it accepts incoming OTLP trace data from your application, and it serves the dashboard that visualises those traces. The server writes all trace data to a local SQLite database scoped to your project directory. The dashboard connects to the server over Server-Sent Events so new spans appear in real time as your agent runs. The tool is distributed as three packages that work together. @axon-ai/cli is the command-line interface you interact with. @axon-ai/backend is the Express server and database layer. @axon-ai/dashboard is the React web interface. When you install the CLI, it bundles the other two so y","default_branch":null,"files":null,"tree":[],"storefront":"/r/langchain-tracer","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/langchain-tracer/Axon/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
