boldrouter
boldrouter is a Swiss-hosted unified LLM gateway that gives developers and businesses one API key to access leading large language models from providers such as OpenAI, Anthropic, Google, xAI, DeepSeek, Perplexity, Mistral, Z.ai, and more. Built around an OpenAI-compatible integration, boldrouter lets teams continue using familiar SDKs and workflows while switching between models by changing a single model string, reducing the need to manage separate provider accounts, integrations, keys, and billing systems.
The platform is designed to simplify AI infrastructure with smart routing, automatic failover, token-accurate metering, prepaid billing, scoped API keys, and usage analytics. Developers can route requests based on price, latency, uptime, and provider availability, while tracking spend, tokens, and performance from one dashboard. By combining access, reliability, billing, and analytics in one gateway, boldrouter helps teams build, test, and scale AI applications faster across multiple model providers.
