Compare
Probe0 next to everything else in the space.
Gateways, gateways-as-a-service, cost dashboards, and the odd wrapper CLI. Each page is a real, checkable comparison — not a list of reasons to avoid the other tool.

Open-source (Apache-2.0) LLM observability, analytics, and prompt-management platform for teams, available as hosted cloud or self-hosted Docker.
Probe0 vs Martian
A hosted, OpenAI-compatible LLM gateway with a trained model router that predicts which model can answer a given prompt acceptably and sends it to the cheapest one.
Probe0 vs Not Diamond
A hosted intelligent model router: you send request context, it returns a recommendation for which model to use, and you make the actual LLM call yourself.
Probe0 vs Ollama
A local model runner that pulls and serves open-weight models on your own machine behind an OpenAI-compatible endpoint, with an optional hosted cloud tier for models too large to run locally.
