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

Most monitors tell you a job pinged. RunVouch tells you whether it did the work: it records the start, end, cost, tokens, tool calls and the evidence a run should leave behind, and alerts when any is missing. A run that never started, one that stalled, one that exited non-zero, one looping in a retry storm, one over its cost cap, and the one no heartbeat monitor catches: a run that reported ok while its output was never written. Every finished run is hashed into a leaf, every day of leaves into a Merkle root, chained to the day before and stamped into Bitcoin with OpenTimestamps: a report cannot be edited afterwards, not even by us. Anyone can verify a sealed run in the browser, without an account, and edit a field to watch the hashes break. The client is one dependency-free Python file that wraps any command and fails open, so monitoring cannot break the job. Claude Code, OpenClaw, n8n, GitHub Actions, cron, systemd, Slack, MCP. Free for 20 agents. MIT, self-hostable.

Audience

AI engineering and platform teams that need to evaluate, monitor, and improve production AI agents for quality, drift, risk, and cost in real time

Audience

Developers and small teams running scheduled work without anyone watching: cron jobs, Claude Code routines, headless AI agents, n8n workflows and CI schedules. Also audit and compliance teams that need a tamper-evident record of what an automated system did.
