Kong AI Gateway is a control plane for teams routing traffic across multiple LLM providers, offering unified OpenAI-compatible API access, automatic fallback, semantic caching, token-based spend limits, PII sanitization, and MCP/agent-to-agent governance. It targets platform and security engineering teams that need centralized AI access control, observability, and audit logging across providers. Paid plans start at $105 per seat per month with no sales call required, and a fully self-hosted open-source option (Kong Gateway 3.9.1 and earlier) is available at no cost. The platform holds SOC 2 Type 2 certification, is GDPR and PCI DSS compliant, and publishes an SLA.

Best for / Avoid if

Best for: Prototypes and side projects - free to start, no sales call; Regulated or enterprise workloads - compliance attestations and an enterprise plan; AI agents and automation - an agent-ready surface (MCP / llms.txt)
