RouterBase is a unified API gateway that gives developers and teams access to 200+ frontier AI models — including GPT, Claude, Gemini, Llama, Mistral, and DeepSeek — through a single OpenAI-compatible endpoint.

Instead of integrating and maintaining separate SDKs, keys, and billing accounts for every provider, you point your existing code at RouterBase and switch between models with one line of configuration. Our smart routing automatically picks the best model for each request, and automatic failover keeps your application running even when an upstream provider has an outage.

Key features include: one OpenAI-compatible endpoint for every model, smart routing and load balancing, automatic fallback across providers, unified billing and usage analytics, and transparent per-token pricing with no markup surprises.

RouterBase is built for AI developers, startups, and engineering teams who want reliability, flexibility, and cost control without vendor lock-in. A free tier is available with no credit card required.
