OpenRouter apps and chat clients that use your own key

OpenRouter is a single API and a single key for hundreds of models from OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek and others. Apps that accept an OpenRouter key let you switch models without managing a key per provider, and you pay OpenRouter for usage from one balance. OpenRouter also has its own BYOK option, where you attach provider keys to your OpenRouter account and requests are billed to those keys.
