The AI Control Plane for the Enterprise Agent Workforce
Building Trust with AI Builders and Guardians
Your Mission Control View Of Every Agent


Fiddler is the AI Control Plane, the system of trust, for first-party and third-party agents from the creation layer to production. Continuous evaluation, reliable monitoring, enforceable policy, and auditable governance give enterprises the centralized controls and actionable insights to scale AI with trust. Integral to the platform are the secure Fiddler Centor Models, which power the industry's fastest guardrails and evaluations at low latency and low cost, without the hidden costs of external LLMs.
Fortune 100 organizations use Fiddler to deliver high performance agentic and predictive applications, protect from costly risks, and maximize ROI.
Fiddler AI is used by organizations deploying agents across all industries, as well as highly regulated industries like financial services, healthcare, insurance, and government.
Within these organizations, the typical users are software and AI engineers, data scientists, platform and DevOps teams, and security and compliance teams responsible for keeping agents and predictive models accurate, safe, and compliant across their lifecycle.
Fiddler is built for enterprises that need one platform to observe, evaluate, and enforce policy across every agent, first-party, third-party, and coding, from the moment code is written through production. Four things set it apart.
First, Fiddler is the only platform spanning both the creation layer, where coding agents write code, and the production layer, where agents run in the business, so governance doesn't stop at deployment.
Second, Fiddler Guardrails enforce policy inline, at the agent's request and response path, in under 80ms, so violations are stopped before data ever leaves your network, not flagged after the fact.
Third, Fiddler Centor Models run in your own environment, eliminating the Evaluation Trust Tax that competitors pass on to you through external LLM API calls for every evaluation.
Fourth, Fiddler is model- and cloud-agnostic, working across Azure OpenAI, Amazon Bedrock, LangGraph, and 100+ other providers, so you're not locked into one vendor's ecosystem the way hyperscaler-native tools are.
When evaluating any AI observability platform, ask whether it enforces policy in real time or only monitors after the fact, whether it covers both the creation and production layers, and whether you're paying an external LLM provider every time it evaluates a trace.
We offer three plans, and we work with customers to find the right fit based on their specific use cases and needs, rather than a one-size-fits-all package. The Free plan includes real-time guardrails powered by Fiddler Centor Models at under 80ms latency, protecting against hallucinations, toxicity, PII/PHI, prompt injection, and jailbreak attempts. The Developer plan is usage-based at $0.002 per trace and adds unified observability for agentic and predictive systems, custom evaluators, and SSO. The Enterprise plan adds enterprise-grade guardrails, flexible deployment (SaaS, VPC, or on-premises), infrastructure scalability, and white-glove support with a named Customer Success Manager and customized onboarding.
