Where Portkey is strong
Portkey publicly offers gateway routing, guardrails, observability, prompt management, logs, and enterprise controls. Its Production plan is listed at $49 per month with included recorded logs and usage-based log overages.
Where Layer8 is different
Layer8 focuses on durable execution beyond the provider response: specialist validation channels, bounded reason-coded repair, weakest-link gates, human approval, and complete decision provenance.
How to choose
Choose based on the workflow you need to govern. Teams primarily seeking a mature gateway and observability product should evaluate Portkey directly. Teams needing controlled multi-stage execution and evidence-sensitive release should evaluate Layer8 as it reaches pilot readiness.
