Editorial take
Why it stands out
Fiddler AI should be framed as production AI control infrastructure, not as a generic analytics dashboard for prompts.

Tool profile
AI observability and security platform for production agents, LLM apps, and ML systems with guardrails, trace-based pricing, and enterprise deployment options.
AI observability
Fiddler AI belongs in the catalog because it is aimed squarely at teams trying to operate AI systems in production rather than just prototype them. The checked official site and pricing page frame the product around observability, security, tests, experiments, unified diagnostics, and enterprise-scale guardrails for agentic, LLM, and predictive systems. That makes it relevant to a premium buyer audience evaluating how to monitor, test, and govern real AI deployments once reliability and risk become business concerns.
It also deserves inclusion because the pricing page is unusually concrete for this category. The checked official pricing page exposes a Free guardrails offering, a Developer path priced at $0.002 per trace, and an Enterprise tier for broader governance, scalability, and flexible deployment. The official guardrails docs also publish rate limits for the free experience. That combination is enough to produce an honest, buyer-useful pricing entry without pretending the whole platform is self-serve.
