One OpenAI-compatible API key for 500+ AI models
Replace separate OpenAI, Anthropic and Google credentials with a single key and switch models by changing one line of code.
Route text, reasoning, coding, image, audio and video workloads through one OpenAI-compatible base URL without rewriting your app.
Line-item pricing per model with discounts below official vendor rates, pay-as-you-go with no monthly subscription or minimum spend.
A real-time dashboard tracks spend, latency and call volume so you can set budget alerts and compare models side by side.
One OpenAI-compatible gateway for adaptive LLM routing, guardrails, and spend control
Each prompt is graded and routed to the model that clears your quality bar, with configurable fallback chains that retry before a response starts.
Pay provider prices with $0 per-token added on pay-as-you-go and subscriptions, or bring your own provider keys and credits.
PII shielding, jailbreak and injection blocking, and per-call approval for tool and MCP actions run before you are billed.
Request logs, per-prompt receipts, routing and spend dashboards, and copy-as-cURL make every call auditable and attributable.

SpecialistGoogle's rapid prototyping IDE and developer API workbench for building multimodal applications with Gemini models.
Provides access to a massive catalog of frontier models with flexible routing, but lacks OrcaRouter's dedicated enterprise governance.

SpecialistExcels at serverless generation of media models like images and video, but is less focused on general LLM routing.
#3
SpecialistSpecializes in high-performance serverless inference for open-source models, but offers fewer proprietary commercial model options.
Offers unified access to multimodal language and media models, but focuses more heavily on generation infrastructure.

Free / Open-sourceOffers an open-source proxy and SDK for unifying 100+ LLMs with failover, requiring self-hosting rather than a managed service.


Routes requests across frontier models with automatic failover and analytics, serving as a straightforward alternative API proxy.

One API for LLM, image, video, and audio models in production
SpecialistProvides optimized inference for open-weight models behind a unified API, though with different regional pricing structures.
Gives developers a single OpenAI-compatible endpoint for multiple LLMs with failover, but offers fewer advanced routing rules.

Aggregates hundreds of foundation models and agent tools into a single endpoint, but has different rate limits.
Delivers enterprise-grade LLM gateway features with advanced caching and observability, though at a higher operational complexity.
