Spanlens is an open-source observability tool under the MIT license that allows developers to seamlessly monitor their applications' interactions with various services, including OpenAI, Anthropic, and others. The integration is remarkably straightforward; developers can either modify the client's baseURL to point to the Spanlens proxy with a single line of code or use the command "npx @spanlens/cli init," which activates a wizard for automatic code adjustments. After integration, the platform logs all requests in detail, tracking essential metrics such as model type, token counts, latency, costs, and the entire prompt and response body, while also effectively reconstructing streaming outputs. The platform's dashboard converts this extensive log information into valuable operational insights. With cost tracking capabilities, users can analyze their spending by specific requests, models, and users, along with differentiating prompt-cache tokens to clarify actual savings beyond total costs. Furthermore, agent tracing illustrates multi-step workflows through Gantt waterfalls and node-and-edge graphs, highlighting critical paths to help developers identify the slowest dependencies in complex scenarios. This thorough approach not only improves visibility but also equips users with the tools necessary to refine their model interactions for enhanced efficiency and effective cost management, fostering a more productive development environment overall.
