No counterpart
Fiddler AI sells these in a stack layer with no product recorded for Workday yet — nothing on the other side to compare them against.
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.
Platform
AI observability platform: evaluation, monitoring and real-time guardrails for ML models and generative AI/agentic applications in production.
Workday sells these in a stack layer with no product recorded for Fiddler AI yet — nothing on the other side to compare them against.
