Products, side by side
Algorithmic pairing — assembled from recorded fields, not hand-checked
Fiddler AI
Platform
AI observability platform: evaluation, monitoring and real-time guardrails for ML models and generative AI/agentic applications in production.
TrueFoundry
Platform
TrueFoundry's AI Deployment Platform enables teams to build, track, and deploy models on Kubernetes.
No counterpart
Fiddler AI sells these in a stack layer with no product recorded for TrueFoundry yet — nothing on the other side to compare them against.
Application
Governance module within the Fiddler AI Control Plane providing model inventories, policy enforcement and audit-ready reporting for regulatory compliance (e.g. EU AI Act) across an organization's AI systems.
Tracing and monitoring module for multi-step agent workflows within the Fiddler AI Control Plane, tracking tool calls, reasoning steps and failures across an agent's execution.
Ongoing automated evaluation module within the Fiddler AI Control Plane that re-scores production LLM/agent outputs against quality and safety metrics over time, not just at launch.
Runtime safety layer within the Fiddler AI Control Plane that screens LLM/agent inputs and outputs for hallucination, toxicity, PII and jailbreak attempts before they reach users.
Developer tool
Source-available library for red-teaming and robustness testing of LLMs, run independently of the hosted Fiddler platform. Fiddler's own page calls it "open-source"; its repository's actual licence is the Elastic License 2.0, which is not an OSI-approved open-source licence (it restricts offering the software as a competing hosted service), so it is recorded here by its real terms rather than the vendor's label.
TrueFoundry sells these in a stack layer with no product recorded for Fiddler AI yet — nothing on the other side to compare them against.
API service
Provides unified access to AI models with request routing, usage monitoring, access controls, and safety guardrails.
Agent platform
Open-source, vendor-neutral agent harness: one runtime with context engineering, sandboxed tool execution, sub-agents, human approvals, generative UI streaming and tracing, bring-your-own model, plugged into TrueFoundry's AI Gateway; the managed version is sold as Agent Harness.
Infrastructure service
Runs and governs AI agents through a centralized gateway.
Connects, secures, and manages MCP servers through a unified gateway.
