HumanLayer is an API and SDK that enables AI agents to contact humans for feedback, input, and approvals. It guarantees human oversight of high-stakes function calls with approval workflows across Slack, email, and more. By integrating with your preferred Large Language Model (LLM) and framework, HumanLayer empowers AI agents with safe access to the world. The platform supports various frameworks and LLMs, including LangChain, CrewAI, ControlFlow, LlamaIndex, Haystack, OpenAI, Claude, Llama3.1, Mistral, Gemini, and Cohere. HumanLayer offers features such as approval workflows, human-as-tool integration, and custom responses with escalations. Pre-fill response prompts for seamless human-agent interactions. Route to specific individuals or teams, and control which users can approve or respond to LLM requests. Invert the flow of control, from human-initiated to agent-initiated. Add a variety of human contact channels to your agent toolchain.

Traccia is an OpenTelemetry-native observability, governance, and policy enforcement platform for production AI agents. It gives engineering teams complete visibility into every LLM call, tool invocation, decision, token, and dollar spent across frameworks like LangChain, CrewAI, OpenAI Agents SDK, AutoGen, and LlamaIndex. Beyond tracing, Traccia helps organizations govern AI systems with runtime policies that can detect and block unsafe behavior, runaway costs, restricted model usage, and PII exposure before incidents reach production. Accurate cost attribution, agent health monitoring, a unified agent registry, and EU AI Act evidence generation make it suitable for enterprise deployments. With a lightweight open-source SDK and managed platform, Traccia enables teams to build, debug, monitor, and govern AI agents at scale without vendor lock-in, using standard OpenTelemetry instrumentation.
