Portkey
AI gateway with guardrails
Free tier + paidModel APIs, routers & observabilityportkey.ai
What it is
An AI gateway that sits between your app and providers: one API for 250+ models with automatic fallbacks, load balancing, retries, semantic caching, budget-capped virtual keys and guardrails, plus built-in observability. It is a control plane, not a model host.
Why it earns a slot
When one provider going down must not take your app with it, Portkey fails over automatically. Virtual keys with hard budget caps stop a runaway loop or a leaked key from producing a five-figure bill.
Know before you commit
The free tier keeps logs for only 3 days, often too short to debug an incident reported the next week. The hosted gateway adds a network hop unless you self-host it.
Getting started
npm i portkey-ai (or pip install portkey-ai)
