A safety checker for AI systems that catches hallucinations, unsafe answers and factual mistakes before they reach a user, using its own purpose-built judge models instead of relying on a general-purpose LLM to grade itself.

Best alternatives to AgentX in 2026
Building an AI agent is one thing; trusting it enough to let it talk to real customers unsupervised is another. AgentX exists for that gap — it's a testing ground where you can run your agent through many scenarios, see exactly where it hallucinates or goes off-script, and get a one-click suggested fix before anything embarrassing happens in production. AgentX is an AI agent orchestration and evaluation platform: build multi-agent systems with defined roles, instructions, and model choices, then run them through an LLM-as-judge evaluation layer that flags hallucinations and behavioral drift, tracks regressions with versioning and one-click rollback, and inserts human-in-the-loop checkpoints where needed. It integrates with LangChain, CrewAI, the OpenAI Agents SDK, and Google's ADK, deploys agents to API, Slack, web widgets, email, or voice channels, and offers SOC 2 compliance with encryption and role-based access control for teams that need that assurance. Pricing runs free (200 credits) up to Solo Builder ($49/month), Professional ($199/month, white-label), and Business ($299/month, white-label), with custom pricing for managed enterprise engagements.
