Portkey — Production Stack for Gen AI Builders

Portkey is a freemium, production-grade platform designed for AI/GenAI engineering teams building and deploying LLM-powered applications at scale. At its core is a unified AI Gateway that provides a single API interface to 1,600+ LLMs across multiple providers, eliminating per-provider integration overhead.

Key technical capabilities:

  • Unified API — Route requests to 1,600+ LLMs through one consistent interface, with support for fallbacks, load balancing, and retries
  • Real-time observability — Monitor latency, cost, token usage, and errors via a live dashboard
  • Prompt management — Version-controlled prompt templates with collaborative tooling
  • Guardrails — Configurable safety and validation layers on LLM inputs and outputs
  • AI Governance — Role-based access control (RBAC), per-user/team budget limits, and rate limiting
  • Caching — Both semantic and deterministic caching strategies to reduce redundant LLM calls and lower costs
  • MCP Gateway — Secure, managed access to MCP servers
  • Compliance — SOC2 Type 2, GDPR, and HIPAA certified; supports private cloud deployment and SSO at the Enterprise tier

Portkey is self-hostable and exposes a full API. It integrates with Microsoft Azure, MongoDB, GitHub, Docker, Cloudflare, Figma, Auth0, OpenAI, and LibreChat.
