9 Best AI Gateways in 2026: Bifrost, Portkey, LiteLLM, Kong and 5 More Ranked

AI gateways are middleware layers that sit between applications and large language model APIs, handling routing, rate limiting, caching, observability, and governance in a single place. As organizations adopt multiple models from different providers, these tools have become essential infrastructure for managing complexity, cost, and compliance.

MarkTechPost's 2026 roundup evaluates nine gateways across several dimensions. Open-source options like LiteLLM and Kong offer flexibility and self-hosting, while managed services such as Portkey, Bifrost, and Orq.ai emphasize ease of deployment and built-in governance features. Cloudflare and Vercel bring gateway capabilities into their existing developer platforms, lowering the barrier for teams already on those ecosystems.

The comparison highlights trade-offs between latency optimization, pricing models, licensing terms, and governance controls. Teams choosing a gateway must weigh the need for fine-grained control against the operational overhead of self-managed deployments, and consider how well each tool handles multi-model routing and failover.

The growth of this category reflects a broader trend: as AI applications move from prototypes to production, the infrastructure layer around model access is maturing rapidly. Organizations are increasingly treating gateway selection as a strategic decision comparable to choosing a cloud provider or API management platform.
