Portkey

Portkey is the production stack for teams building with generative AI. It brings the four capabilities that ship-ready AI applications depend on — an AI Gateway, observability, guardrails, and prompt management — together with governance tooling inside a single platform, so organizations can democratize and productionize Gen AI across every team rather than bolting components together themselves. Portkey is open source and already powers more than 3,000 GenAI teams.

The AI Gateway is the connective tissue of the stack. Through one unified API, developers access over 1,600 large language models, which means swapping providers becomes a configuration change instead of a rewrite. Observability sits on top of that gateway, exposing real-time dashboards that monitor LLM behavior, surface anomalies early, and let teams manage usage proactively instead of reacting to incidents after the fact. Guardrails keep outputs in check, prompt management removes the need to hard-code prompts, and governance ties everything together with the controls an enterprise expects.

Portkey is built for the realities of production AI, where cost, reliability, and safety matter as much as model quality. Features such as caching deliver clear ROI — customers report saving thousands of dollars on repeated calls — while the unified access layer eliminates the guesswork of integrating new models. The platform integrates with the tools developers already use, including Microsoft Azure, MongoDB, GitHub, Docker, and Auth0. With its recent acquisition by Palo Alto Networks, Portkey is positioned to bring enterprise-grade security and governance to Gen AI at scale, making it a no-brainer for any team taking AI from prototype to production.
