Open-source AI infrastructure
Compare Everstack and Portkey across multi-provider routing, LLM observability, agent runtime ownership, isolated execution, governance, and self-hosting.
Palo Alto Networks has completed its acquisition of Portkey, and the product is now sold as Prisma AIRS AI Gateway. Acquisitions of infrastructure vendors routinely bring repricing, enterprise repackaging and roadmap reprioritisation, which is worth planning for. It also means stronger continuity and compliance answers than a young independent vendor can give, so this cuts both ways depending on your buyer.
Portkey is a strong gateway: multi-provider routing, guardrails, semantic caching, and a mature observability surface over model traffic. The layers past the request stay external. Everstack carries the same request into a stateful agent runtime, isolated Docker, Firecracker and Kubernetes sandboxes, evaluations, and OpenTelemetry traces that span all of it.
Portkey was acquired by Palo Alto Networks and is now sold as Prisma AIRS AI Gateway, which Palo Alto Networks announced as generally available on 16 July 2026. Acquisitions of infrastructure vendors reliably bring repricing, enterprise repackaging, and roadmap reprioritisation. Whether that helps or hurts depends on whether your requirements line up with a security platform's roadmap.
If the problem is model routing and you want a managed product with guardrails and observability working on day one, Portkey is the faster path and now carries enterprise backing. The case for Everstack rests on needing the runtime and execution layers under the same control plane, on your own infrastructure.
