Probe0 next to everything else.

Gateways, hosted gateways, cost dashboards and the odd wrapper CLI. Each page is a real, checkable comparison, not a list of reasons to avoid the other tool.

A local model serving and distribution layer bundled with Docker Desktop, running GGUF and safetensors models on host hardware behind an OpenAI-, Anthropic-, and Ollama-compatible API.
Probe0 vs Eden AI
A hosted, multi-tenant AI API gateway that fronts hundreds of models across LLMs and non-LLM services like OCR, speech and translation under one key and one bill.

Probe0 vs Kosmoy
An enterprise AI control plane (gateway, governance, observability, agent sandboxing) that organizations self-host in their own Kubernetes cluster.
Probe0 vs Langfuse
Open-source LLM observability and evaluation platform (tracing, evals, prompt management), run as Langfuse Cloud or self-hosted, with data arriving through SDK instrumentation.

LangChain's commercial, framework-agnostic platform for tracing, evaluating and monitoring LLM agents, delivered as hosted SaaS with a self-hosted option on its Enterprise tier.
Probe0 vs LiteLLM
An open-source (MIT) Python SDK and self-hosted proxy server that puts one OpenAI-compatible endpoint in front of 100+ model providers.
Probe0 vs llama.cpp
An open-source C/C++ inference engine (MIT) that runs GGUF models locally, with llama-server exposing an OpenAI-compatible HTTP API.
Probe0 vs LM Studio
A desktop app and local API server for downloading and running open-weight models on your own machine, built on llama.cpp and Apple MLX.
Probe0 vs LocalAI
An MIT-licensed, self-hosted inference server with an OpenAI-compatible API that runs models locally across dozens of backends.
Probe0 vs Lunary
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.
Probe0 vs Open WebUI
A self-hosted, provider-agnostic chat platform and workspace that sits in front of Ollama and OpenAI-compatible backends, built for teams of humans in a browser.
Probe0 vs OpenLLMetry
