Portkey
Gateways & routersAn AI gateway pairing fast model routing with built-in observability, caching, and guardrails.
Portkey is an AI gateway with an open-source core and a hosted option. It routes across providers with fallbacks and load balancing, and folds in observability, caching, and guardrails — so the control plane and the visibility plane are one thing.
For teams that would otherwise wire a gateway and a separate monitoring tool together, that consolidation is the appeal.
Where it's ideally used
A good fit when you want routing and observability from one layer rather than integrating a gateway and a monitoring tool separately.
Where it doesn't fit
More surface than needed if you only want bare routing and already run your own observability stack.
