Martian alternatives
3 substitutes · 3 in routing · 0 adjacent
The short answer
3 tools on this index are recorded as a substitute for Martian. 2 of these run the same way you already deploy Martian (saas), and 1 is permissively licensed, so it does not change what you can ship. All of them sit in Routing & Gateways, 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 Martian you have already built around.

This graph is bidirectional and unsponsored. A tool appears here if Martian or another entry names it as a substitute, and OpenRouter, RouteLLM and Not Diamond point at Martian as well. How this index is compiled — including where it is wrong.
