When your apps connect to several language-model providers, a gateway can centralize how those connections are managed. Compare provider count and self-hosted deployment with fallback routing, budget controls, usage analytics, and virtual API keys to see which capabilities match your workflow. Free-plan availability and paid-from pricing add cost context. The ranking begins with OpenRouter, LiteLLM, and Requesty, with TrueFoundry AI Gateway and Bifrost among the next entries. Consider how you want to manage provider access, respond when a route is unavailable, and keep track of usage as you weigh the listed features.
