TrueFoundry vs Kong AI Gateway
Both are llm gateways tools. Here is how they actually differ on price, billing model and deployment.
TrueFoundry
An enterprise AI gateway fronting 250+ models with on-prem deployment and a free developer tier. Worth knowing that it also publishes the competitor pricing guides that rank highly for its rivals' names.
Kong AI Gateway
AI routing built into Kong's established API gateway. The right answer if Kong already fronts your APIs and governance is the priority - an expensive one if you are adopting Kong just for this.

Our verdict on TrueFoundry
TrueFoundry is a credible enterprise AI gateway with one capability that genuinely distinguishes it - it deploys on-premise and in your own cloud, not just as SaaS. For regulated organisations that cannot route prompts through a third party but also do not want to own an open-source proxy outright, that middle position is valuable and few competitors occupy it. Native MCP support and semantic caching are both ahead of most of the field, and the free Developer tier at 50,000 requests a month is a real trial. The company looks solid, having raised over $21 million from Intel Capital, Eniac Ventures and Peak XV, appeared in Gartner's 2026 Hype Cycle for Platform Engineering, and acquired Seldon AI. One thing worth knowing as a reader rather than a buyer. TrueFoundry publishes detailed pricing guides for LiteLLM, Portkey, LangChain and others, and those articles rank well for competitor searches. They are reasonable content, but they are competitor marketing, and if you have been researching gateway pricing you have probably read several without noticing whose site you were on.
Full TrueFoundry review →Our verdict on Kong AI Gateway
Kong AI Gateway is a straightforward proposition that depends almost entirely on one question - do you already run Kong? If you do, this is close to an obvious choice. LLM traffic comes under the same policy, authentication, rate limiting and governance as the rest of your APIs, managed by the same platform team through the same control plane, rather than existing as a parallel system nobody owns. For an organisation where API governance is already a formal function, that consolidation is worth more than any LLM-specific feature. If you do not already run Kong, the calculation inverts sharply. Konnect is reported at roughly $500 to $2,500 a month against Cloudflare AI Gateway's $5 or self-hosted LiteLLM's infrastructure cost, and the LLM-specific capabilities are thinner than dedicated AI gateways. You would be adopting a substantial API management platform to solve a problem that cheaper, more focused tools solve directly.

What is the main difference between TrueFoundry and Kong AI Gateway?
TrueFoundry: Enterprises that need an AI gateway deployable on-premise or in their own cloud with governance features, and that want a managed product rather than operating open-source infrastructure. Kong AI Gateway: Organisations already standardised on Kong for API management, where bringing LLM traffic under existing governance matters more than LLM-specific features. Both sit in LLM Gateways, so the decision usually comes down to billing model and deployment rather than raw capability.
Which is cheaper, TrueFoundry or Kong AI Gateway?
It depends entirely on your workload shape, because they meter differently - TrueFoundry bills on request and Kong AI Gateway bills on no usage metering. Published starting prices are $499/mo and Around $500/mo (Konnect) respectively, but those numbers are not comparable until you apply them to the same traffic. Use our cost calculator to model both against your own request volume and span count.
Can I self-host TrueFoundry or Kong AI Gateway?
TrueFoundry: No or paid tier only. Kong AI Gateway: Yes, free. Free self-hosting means no licence fee, not no cost - you still own the infrastructure, upgrades and on-call.
