Gentrace alternatives
4 substitutes · 4 in evals · 0 adjacent
The short answer
4 tools on this index are recorded as a substitute for Gentrace. 3 of these run the same way you already deploy Gentrace (self-hosted), and 3 are permissively licensed, so they do not change what you can ship. All of them sit in Evaluation & Observability, so the choice is a real one rather than a category change. There is no overall winner here: which one is right depends on traffic shape, operational budget and how much of Gentrace you have already built around.

This graph is bidirectional and unsponsored. A tool appears here if Gentrace or another entry names it as a substitute, and Arize Phoenix, Langfuse, Helicone and Opik point at Gentrace as well. How this index is compiled — including where it is wrong.
