Description

Maintain your current web infrastructure while allowing Fanout Cloud to oversee persistent client connections. Simply inform us whenever there’s data to dispatch. It’s designed to scale effortlessly—whether you’re pushing updates to a thousand clients or a million, Fanout's infrastructure is equipped to manage it smoothly. You’re already busy optimizing various components of your application; let us handle this aspect for you. Seamless integration is key—utilize custom domains and data formats or transition an existing real-time API to the cloud without disrupting your clients. Your API remains under your control. Enjoy peace of mind with our robust business-grade SLA, which is included with all paid plans. Furthermore, every account, even those on the hacker tier, comes with built-in SSL for enhanced security. An unexpected surge in traffic should be an opportunity for growth, not a source of stress. Our usage-based pricing model features no rigid limits; we bill based on messages sent and the duration clients are connected (rather than concurrent connections), allowing you to forecast your expenses more accurately. In essence, we enable you to focus on what you do best while we take care of the rest.

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.
