Honest comparison

Mysty PAI vs Portkey

Portkey governs API requests from the cloud. PAI governs the workers themselves — on your hardware, every action approved and signed.

Honest comparison

Side by side

Honest comparison, checked 28 September 2026. Portkey is an excellent AI gateway — now part of Palo Alto Networks, where it serves as the AI gateway for Prisma AIRS. If you need cloud API middleware for a dev team, it's a fine choice. PAI solves a different problem: governing autonomous Pies on Physical infrastructure you own.
