LMSpeed is a web tool for LLM API comparison and testing.
It helps developers compare provider price, speed, first token latency, uptime signals, and model coverage.
It can test OpenAI compatible endpoints with a base URL, API key, and model ID.
It also includes leaderboards, a provider directory, a model library, shared test keys, and relay security checks.
Use it before choosing an API for an app.
Shared keys are for testing, not production.
