Portkey
AI gateway routing, observing, and governing LLM traffic at scale.
About Portkey
Portkey is an AI gateway and LLMOps platform that sits between an application and the large language models it calls. It provides a single OpenAI-compatible API that routes requests to more than 1,600 models, with automatic fallbacks, load balancing, retries, and caching so an application keeps working even if a specific provider has an outage. Every request and response is logged with over 40 details on cost, latency, and accuracy, giving teams a real-time view of how their AI features are actually performing in production. On top of routing and observability, Portkey adds guardrails such as PII redaction and policy enforcement, a prompt management system with versioning, and governance controls including role-based access, virtual keys, and budget limits for different teams or projects. It also offers an MCP gateway for securely connecting AI agents to external tools. The platform integrates in a few lines of code across Node.js, Python, and OpenAI-compatible SDKs, and lists partnerships with MongoDB, GitHub, Docker, Auth0, Figma, and Cloudflare. Portkey was built by Portkey, Inc., based in San Francisco, and has been recognized as a Gartner Cool Vendor in LLM Observability. As of mid-2026, Portkey has become part of Palo Alto Networks' PRISMA AIRS AI Gateway, which may affect its branding and roadmap independent of the original company.
