About
Portkey is a comprehensive LLM operations platform that sits as a middleware layer between your application and LLM providers, giving teams complete visibility and control over every aspect of their AI infrastructure. It acts as a unified AI gateway that routes requests to multiple LLM providers, enforces guardrails, tracks costs, and provides observability — all without requiring code changes beyond adding a single API endpoint.
The platform's AI Gateway supports OpenAI, Anthropic, Google, Cohere, Mistral, and dozens of other LLM providers through a single unified API. Teams can implement automatic fallbacks (if OpenAI is down, switch to Anthropic), load balancing across providers, and A/B testing of different models — ensuring production reliability and cost optimization simultaneously.
Portkey's observability suite captures every request and response with full traces, token counts, latency metrics, and cost calculations. This makes it possible to debug issues, identify expensive prompt patterns, measure quality regressions, and optimize prompts with data rather than guesswork.

About the Publisher
Portkey was founded in 2023 by Ayush Garg and Vrushank Vyas, two engineers who built and scaled AI applications at Postman. Based in San Francisco and backed by Y Combinator, Portkey quickly became a critical piece of infrastructure for companies shipping production LLM applications. The platform processes hundreds of millions of LLM requests monthly and serves engineering teams at companies across fintech, healthcare, and enterprise software who depend on AI reliability and cost predictability.
