Opik alternatives
3 substitutes · 3 in evals · 0 adjacent
The short answer
3 tools on this index are recorded as a substitute for Opik. 3 of these run the same way you already deploy Opik (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 Opik you have already built around.

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