About
Portkey is an AI gateway and production stack for teams building with large language models. It gives developers infrastructure for routing model requests, tracking usage, managing prompts, applying guardrails, and monitoring AI applications across different providers.
The product is useful for founders and engineering teams that do not want to lock their AI product into one model provider or rebuild infrastructure for every new model. Portkey can sit between an application and multiple LLM providers, helping teams route traffic, fallback between models, track costs, inspect requests, and improve reliability.
Portkey also includes observability and governance features, making it relevant for businesses that need more control over AI behavior in production. Teams can manage prompts, monitor latency and spending, enforce guardrails, control API keys, and organize AI usage across users, teams, and environments.
For FutureStack, Portkey should be listed as a developer infrastructure tool for production AI builders. It is a strong fit for SaaS founders, AI product teams, and developers building agents, chatbots, support copilots, AI workflows, or apps that depend on multiple LLM providers. Its best use case is helping teams move from simple LLM prototypes to reliable, observable, and governable production systems.
