RouterBase

RouterBase is an AI API gateway built for developers and small teams that work across multiple model providers. Instead of integrating each provider separately, a single OpenAI-compatible endpoint connects to more than 200 models spanning chat, reasoning, vision, and embeddings, from providers such as OpenAI, Anthropic, Google, and Meta. Because traffic runs through one account, switching or comparing models requires no code changes — only the model name changes. Smart routing can select a provider by price, latency, or availability, with automatic fallback when a provider is down. Usage and cost are tracked in one place across every provider. Pricing includes a free tier with usage-based billing, so cost scales with actual consumption rather than fixed seats.
