About

Prefactor is a real-time evaluation, observability, and reliability platform for production AI agents. It scores every run the moment it happens for quality, drift, cost, and data risk, then wires those evaluations into action so a failing agent is caught live instead of only appearing on a dashboard afterward. Teams can observe every model call, tool invocation, and decision as structured traces and spans, run LLM-as-judge, technical, qualitative, and custom evaluations on each step, and attach context from GitHub, Linear, Jira, databases, internal APIs, or other sources as ground truth. When a run crosses a defined threshold, Prefactor can block or throttle it, pause a sensitive action, or route it to a person for approval, modification, or rejection before execution, with every decision logged. The CLI discovers agents without a platform migration, while TypeScript and Python SDKs provide native support for LangChain, Claude, Vercel AI, OpenClaw, and LiveKit.

About

Vulnify is a runtime authorization service for developers and security teams building AI agents that use tools or APIs. Before a tool runs, the agent sends action metadata—including the agent, action, resource, destination, and record count—and receives an ALLOW, REVIEW, or BLOCK decision with a 0–100 risk score and reasons. Teams can define and test YAML policies through a command-line interface, and add checks using Node.js or Python SDKs, a REST API, or adapters for agent frameworks. Monitor mode records decisions without blocking actions. Fail-closed behavior blocks actions if Vulnify is unavailable unless fail-open is configured. A hash-chained audit log records decisions, and paid plans include human review workflows. Common use cases include governing data exports, external messages, payments, and other agent-initiated actions. Vulnify evaluates action metadata rather than the contents of affected records.
