Evaluate AI agents with precise scoring and targeted improvement guidance.

The service supports testing across diverse AI setups such as standalone language models, orchestrated multi-agent pipelines, automation tools, and stateful long-context interactions. Evaluations measure functional correctness, robustness, safety alignment, and evidence handling while checking against a taxonomy of ten specific failure types including hallucination, instruction drift, and multi-agent handoff errors. Reports include real execution audits drawn from logs or traces, design reviews of proposed architectures, and regression comparisons between versions. Each assessment highlights critical issues like context loss or weak guardrails and supplies concrete recommendations to close performance gaps. Access begins with individual tests at a low fixed price, with bundled options available for iterative optimization or large-scale agent fleets. All results focus on revealing discrepancies between intended design and actual behavior to support more reliable AI development.
Submit standalone LLM prompts or simple agents to receive scores on functional correctness, robustness, and safety along with a breakdown of any detected failure modes such as hallucination or instruction drift.
Test complex orchestrated workflows and multi-agent systems to identify issues like state loss during handoffs, weak guardrails, or long-context degradation before deployment.
Evaluate N8N automations, tool-calling agents, or stateful systems using real logs to check spec adherence, evidence grounding, and regression between versions.

Our take: Agent Tester is a solid productivity choice. It's valued for low entry price starting at $5.99 per test and comprehensive reports covering multiple ai system types and failure modes. The main trade-off is all sales final with non-refundable evaluations. Best when you need reliable, professional output.
