Description

Spanlens is an open-source observability platform licensed under MIT that enables developers to effectively track each interaction their applications have with services like OpenAI, Anthropic, Gemini, Mistral, OpenRouter, Azure OpenAI, or a local Ollama model. The integration process is incredibly simple, requiring just a single line of code to change the client's baseURL to the Spanlens proxy, or by executing "npx @spanlens/cli init," which prompts a wizard to automatically adjust your code. Once integrated, all requests are meticulously logged, capturing details such as the model used, token counts, latency, cost, and the complete prompt and response body, while also seamlessly reconstructing streaming responses. The accompanying dashboard transforms this raw log data into actionable operational insights. Cost tracking functionality allows users to break down expenditures by individual requests, models, and end users, while also distinguishing prompt-cache tokens to provide clarity on actual savings rather than simply the total costs. Additionally, agent tracing presents multi-step workflows visually, using Gantt waterfalls and node-and-edge graphs to emphasize the critical path, enabling developers to pinpoint the slowest dependencies in a fan-out scenario. This comprehensive approach not only enhances visibility but also empowers users to optimize their model interactions for better efficiency and cost management.

Description

As third-party APIs evolve, your code may become reliant on outdated elements, such as when a model ID is phased out, a field is eliminated, or an API version is deprecated. While Dependabot manages package updates, it fails to specify which lines of your code are impacted by these API modifications. Upseam fills this gap by analyzing vendor changelogs and deprecation updates from services like Stripe, Shopify, OpenAI, Anthropic, and Gemini, correlating these changes with your JavaScript, TypeScript, and Python code to pinpoint the exact lines that need attention. Upon identifying the necessary adjustments, it generates a pull request with the appropriate fixes, ensuring that it never directly alters your main branch. Operating in Ask mode by default, you retain control by approving each proposed fix, even for straightforward changes like a model ID that has been renamed. To get started, you can either install the GitHub App or utilize a one-time local report by running npx @upseam/cli inspect, which does not require any account setup or installation. Upseam is currently free to use during its beta phase, offering a valuable tool for developers to maintain their code without the hassle of manually tracking API changes.
