About

OpenRouter is a unified interface for accessing large language models from many AI providers through one API. It helps developers use models from providers such as OpenAI, Anthropic, Google, xAI, Groq, Together, and others without integrating each provider separately. The platform is useful for SaaS founders and AI builders who want to compare models, route requests, control costs, improve uptime, and avoid being locked into a single provider. Its OpenAI-compatible API makes it easier to plug into existing applications, frameworks, and developer tools. OpenRouter also provides model rankings, provider information, apps, documentation, and credit-based usage instead of fixed subscriptions. Developers can buy credits, create API keys, and route calls through supported models based on cost, performance, or availability. For FutureStack, OpenRouter is an essential Developer Tools listing because many AI builders use it as a practical LLM gateway. It is best for developers, indie hackers, and founders building AI apps, agents, coding tools, and prototypes that need flexible model access.
