AgentX

Enterprise platform for building, evaluating and shipping AI agents

Multi-agent orchestration

Design drag-and-drop workflows where each agent has a defined role, instructions, model, memory and tools, with branching logic and human handoff.

Pre-deployment evaluation

Run agents against test sets, score multiple runs per version and track regressions before anything reaches production users.

Runtime evaluation and monitoring

LLM-as-judge scoring and 24/7 behavioural monitoring catch hallucinations and broken tool calls while the agent is live.

Framework-agnostic tracing

Stream traces from LangChain, CrewAI, OpenAI Agents SDK, Anthropic or Google ADK into one pipeline for explainable agent decisions.

Strengths & Pros

+Framework-agnostic tracing works with popular stacks such as LangChain, CrewAI and the OpenAI Agents SDK.
+Clear published tiers from free up to $299/month, plus on-prem and white-label options.
+Human-in-the-loop checkpoints and audit trails suit teams with security or compliance reviews.
