Prefactor Review
Prefactor is the real-time reliability layer your AI agents have been begging for. Forget dashboards that merely show you problems after they’ve already happened. Prefactor evaluates every agent run in production for quality, drift, and risk, then immediately acts on those insights. It’s about intervention, not just observation – catching a failing agent live before it causes mischief, bridging the gap between seeing everything and stopping nothing.
Unleash Your Agents with Predictive Oversight
Prefactor elevates your agent development lifecycle from reactive monitoring to proactive enforcement. Its core capabilities ensure your AI operates within defined parameters, always:
- Real-time Evaluation: Instantly score every agent run for quality, drift, and risk, ensuring immediate feedback on performance.
- Runtime Enforcement: Implement policies to hold, approve, or block high-risk actions the moment they occur, preventing undesirable outcomes.
- Seamless Integration: Drop into your stack in minutes with TypeScript & Python SDKs, featuring native support for LangChain, Claude, and more.
- Custom Spans: Ground your evaluations by injecting context from any datasource – GitHub, Jira, internal APIs – directly into the agent’s run.
- Versioned Promotions: Manage agent deployments like software, with eval-gated promotion through dev, staging, and production environments.
