About

Spanlens is an open-source (MIT) LLM observability platform that lets developers monitor every call their application makes to OpenAI, Anthropic, Gemini, Mistral, OpenRouter, Azure OpenAI, or a local Ollama model. Integration takes one line: swap your client's baseURL to the Spanlens proxy, or run "npx @spanlens/cli init" and the wizard rewrites your code automatically. From that moment, every request is recorded with its model, token counts, latency, cost, and full prompt and response body, with streaming responses reconstructed automatically. The dashboard turns that raw log into operational insight. Cost tracking breaks spend down per request, per model, and per end user, and parses prompt-cache tokens separately so you see real cache savings rather than sticker price. Agent tracing visualizes multi-step workflows as Gantt waterfalls and node-and-edge graphs, highlighting the critical path so you can find the slowest dependency chain in a fan-out.

About

White Circle is a unified AI control platform designed to provide end-to-end visibility, safety, and performance optimization for AI systems by combining testing, protection, monitoring, and improvement into a single integrated layer. It acts as a centralized control system that sits between AI models and users, analyzing every input and output in real time to ensure compliance with safety, security, and quality standards. It includes automated stress-testing capabilities that simulate risky prompts and real-world attack scenarios, allowing teams to detect vulnerabilities such as hallucinations, prompt injections, data leaks, and policy violations before deployment. It also features a protection layer that enforces custom rules through low-latency guardrails, blocking, rewriting, or flagging unsafe outputs instantly while preventing misuse of tools, unauthorized actions, or exposure of sensitive information.
