OmniRoute is an open-source AI gateway that aggregates many model providers behind a single OpenAI-compatible interface. A major focus is automatically combining documented free tiers from numerous providers so users can route requests across a large catalog of models without manually integrating a different SDK, authentication flow, and rate-limit strategy for every service.

The gateway provides automatic routing modes optimized for balanced use, coding quality, or low latency, while still allowing callers to target specific backends. It tracks provider availability and free-tier capacity, exposes the information through a dashboard, and is designed so a fresh installation can begin using supported no-key routes immediately. Quick-start examples are provided for common programming languages and cURL.

OmniRoute is useful for developers, hobbyists, and agent builders who want one endpoint for experimenting with many LLMs or reducing inference costs by taking advantage of available free capacity. Its routing layer can also simplify migration between providers, because applications can keep a consistent API while the gateway handles model selection and provider-specific differences.
