Portkey is an AI gateway that puts monitoring first. It sits between your app and your AI providers and adds logs, caching, guardrails and budget controls.
How it works
Requests pass through Portkey, which records cost and latency, can serve repeated requests from a cache, applies rules and guardrails, and retries or falls back when a provider fails. Reports in 2026 say its core was released as open source, with a hosted version as well.
