Product Description

Portkey is a production-grade AI infrastructure platform that provides a unified AI gateway to access 250+ model providers, equipped with comprehensive observability, guardrails, governance, and prompt management capabilities. In March 2026, Portkey fully open-sourced its gateway, including previously SaaS-subscription-only features such as governance, observability, authentication, and cost control, processing over 1 trillion tokens daily. Portkey was recognized as a Gartner Cool Vendor in LLM Observability (2025).

Relationship with OpenClaw Ecosystem

As an AI gateway and observability platform, Portkey is a critical infrastructure component of the OpenClaw ecosystem. OpenClaw can use Portkey to uniformly manage calls to various LLM providers, gaining automatic failover and load balancing capabilities. Its fully open-sourced gateway (2026) aligns perfectly with OpenClaw's open-source philosophy. The MCP gateway capability provides a standardized solution for governing OpenClaw's AI agents, while the observability suite offers comprehensive data support for monitoring and optimization.
