Overview
Portkey is an enterprise-grade AI Gateway and LLMOps control plane designed to make production AI applications fast, reliable, and cost-efficient. By acting as a unified proxy between your applications and 250+ LLMs, Portkey handles automated provider fallbacks, load balancing, rate-limiting, and semantic caching with zero code changes. Engineering teams use Portkey to eliminate single-provider downtime risks (e.g. automatic failover from OpenAI to Anthropic during outages) while cutting inference latency and API costs by up to 40% through intelligent semantic caching.
Portkey provides comprehensive real-time observability, tracing every request, token cost, and latency percentile in a unified dashboard. The gateway supports fine-grained budget limits, user-level rate-limiting, and content moderation guardrails to protect production systems from abuse. With ultra-fast 10ms gateway overhead and SOC 2 Type II compliance, Portkey is engineered for high-throughput enterprise workloads.
The most popular framework for developing applications powered by large language models, including agents and RAG.
Provides components for memory, data retrieval, and tool usage.
