10 Things You Should Know About Kong AI Gateway
- 1 Kong AI Gateway extends Kong's established API gateway with AI routing capabilities
- 2 Kong Konnect is reported at approximately $500 to $2,500 per month, with enterprise pricing on request
- 3 The underlying Kong Gateway is open source with a self-hosted path
- 4 It is positioned for teams already standardising API management on Kong
- 5 Pricing figures are third-party reported rather than published
Pros & Cons
Pros
- ✓ If Kong already fronts your APIs, LLM traffic falls under the same policy, auth and rate limiting rather than a parallel system
- ✓ Genuinely mature governance inherited from a long-established API gateway rather than built new for AI
- ✓ The underlying Kong gateway is open source, so there is a self-hosted path
- ✓ One control plane for conventional and AI traffic is a real operational simplification for platform teams
- ✓ Sensible fit for organisations where API governance is already a formal function
Cons
- ✕ Adopting Kong solely to get an AI gateway is a very large commitment for the benefit
- ✕ Konnect pricing is reported at roughly $500 to $2,500 a month, far above Cloudflare's $5 or LiteLLM's infrastructure cost
- ✕ Pricing figures are third-party reported rather than published, so treat them as indicative
- ✕ No evaluation or LLM-specific observability - it governs traffic rather than assessing quality
- ✕ LLM-specific features are thinner than dedicated AI gateways like Portkey or TrueFoundry
Features
One question decides this
Do you already run Kong?
If yes, Kong AI Gateway is close to an obvious choice. If no, it is an expensive way to solve a problem that cheaper tools solve directly.
Very little else about the product changes that calculation, so it is worth answering first.
The argument, when it applies
The case for Kong AI Gateway is not that its LLM features beat dedicated AI gateways. They generally do not.
The case is that LLM traffic stops being a special case.
Same policy engine. Same authentication. Same rate limiting. Same control plane. Same platform team. Same audit trail.
In an organisation where API governance is a formal function - with owners, review processes and compliance requirements - AI traffic sitting outside that system is itself the problem. A separate gateway means a separate policy surface, separate credentials, separate rate limits and separate people who need to understand it.
Consolidating that is worth more to a platform team than any feature comparison, and it is the reason Kong appears in this category at all.
That is a platform-team concern rather than an application-team one, which is worth noticing because the two will weigh this decision very differently. Work out who is actually choosing.
The cost, in and out of context
Kong Konnect is reported at roughly $500 to $2,500 per month, with enterprise pricing on request.
Compared directly with alternatives, that looks poor:
| Option | Cost |
|---|---|
| Cloudflare AI Gateway | Core free, $5/mo for 1M logs |
| LiteLLM self-hosted | ~$200–500/mo infrastructure |
| Kong Konnect | ~$500–2,500/mo |
But that comparison misleads for the intended buyer. A Kong customer is already paying for Konnect to manage conventional APIs - the AI gateway is an extension of existing spend, not a new line item.
Judge it as incremental cost if you already run Kong, and as a very expensive gateway if you do not.
Two caveats on the figures. They are third-party reported rather than published, and Kong’s pricing generally depends on the scope of your API management deployment rather than AI usage specifically, which makes any single number hard to state meaningfully. If you are a customer, your account team can give you the real incremental figure.
Self-hosting exists
The underlying Kong Gateway is open source, with AI plugins available on it, so there is a genuine self-hosted path - similar in spirit to LiteLLM, though with a very different architecture and operational model.
The honest qualification: Kong Konnect is the managed control plane, and the governance capabilities that make Kong attractive to enterprises are largely what you pay for. The open-source route is real, but it delivers a different product from the one that justifies the enterprise pricing.
It governs, it does not evaluate
No evaluation. No LLM-specific quality measurement. LLM-specific observability thinner than dedicated tools.
Kong AI Gateway handles routing, policy, authentication, rate limiting and transformation. As with LiteLLM and Cloudflare AI Gateway, the expected architecture is the gateway in the request path with Langfuse or Logfire receiving traces and an eval framework alongside.
Do not expect governance depth to extend into quality measurement. Those are unrelated problems that happen to sit near each other in the stack.
Its LLM-specific features are also thinner than Portkey’s or TrueFoundry’s - no semantic caching, no native MCP support, none of the AI-native handling those products have built.
Should you use it?
Use Kong AI Gateway if Kong already fronts your APIs and bringing LLM traffic under existing governance is the priority.
Don’t use it if you are not already a Kong customer. Adopting an API management platform to get an AI gateway is disproportionate, and Cloudflare, LiteLLM or a dedicated AI gateway will serve you better for far less.
Bottom line: a sound extension of an established platform, valuable in exactly one situation and hard to justify outside it. If you are already a Kong shop, ask your account team what the incremental cost is - that number, not the comparison table, is your actual decision.

Our Verdict
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.

Nobody choosing a gateway today. The RouterBench work remains worth reading if you are evaluating routing approaches generally.
LiteLLM
Teams with engineering capacity that want provider-agnostic routing with no per-token markup, particularly at volumes where a percentage fee on a managed gateway becomes significant.
Cloudflare AI Gateway
Teams already on Cloudflare who want caching, rate limiting and cost visibility at the edge with no markup, and who have separate tooling for evaluation.
Not Diamond
Teams already running a gateway who want smarter per-request model selection without putting another vendor in the request path, particularly for coding agents where model spend is high and uncontrolled.
Frequently Asked Questions
When does Kong AI Gateway make sense?
When Kong already fronts your APIs. The argument is not that Kong's LLM features beat dedicated AI gateways - they generally do not - it is that your LLM traffic stops being a special case. Same policy engine, same authentication, same rate limiting, same control plane, same platform team. In an organisation where API governance is a formal function with owners and audit requirements, having AI traffic outside that system is itself the problem, and solving it is worth more than a better feature list. If Kong is not already in your stack, none of that applies and the calculation is completely different.
How does the cost compare?
Poorly, if you are looking at it in isolation. Kong Konnect is reported at roughly $500 to $2,500 a month against Cloudflare AI Gateway's core features free with $5 for a million logs, or self-hosted LiteLLM at a few hundred dollars of infrastructure. But that comparison is misleading for the intended buyer, because a Kong customer is already paying for Konnect to manage their conventional APIs - the AI gateway is an extension of existing spend rather than a new line item. Judge it as an incremental cost if you already run Kong, and as a very expensive gateway if you do not.
Are the pricing figures reliable?
Treat them as indicative. The roughly $500 to $2,500 a month range for Konnect comes from third-party comparison sources rather than a published rate card, and enterprise pricing is on request. Kong's pricing generally depends on the scope of your API management deployment rather than on AI usage specifically, which makes a single figure hard to state meaningfully. If you are a Kong customer, your account team can tell you the incremental cost. If you are not, expect a sales conversation about the whole platform rather than about a gateway.
Can I self-host it?
Yes, in the sense that the underlying Kong Gateway is open source and AI plugins are available on it. That gives you a genuine self-hosted path, similar in spirit to LiteLLM though with a very different architecture and operational model. Kong Konnect is the managed control plane on top, and the governance features that make Kong attractive to enterprises are largely what you pay for. So the open-source route is real but delivers a different product from the one that justifies the enterprise pricing.
Does it do evaluation or LLM observability?
No. Kong AI Gateway governs traffic - routing, policy, authentication, rate limiting, transformation. It does not evaluate output quality and its LLM-specific observability is thinner than dedicated tools. As with LiteLLM and Cloudflare, the expected architecture is the gateway in the request path with Langfuse, Logfire or similar receiving traces and an eval framework alongside. Do not expect the governance depth to extend into quality measurement, because those are unrelated problems that happen to sit near each other.
Kong or a dedicated AI gateway?
Kong if your priority is infrastructure governance and consistency with existing API management; a dedicated AI gateway if your priority is LLM-specific capability. Portkey and TrueFoundry offer richer LLM features - semantic caching, MCP support, provider-specific handling. LiteLLM offers broader provider coverage at no markup. Cloudflare offers a free managed edge deployment. Kong's distinctive contribution is that AI traffic and conventional API traffic are governed identically, which is a platform-team concern rather than an application-team one. Work out which team is actually making this decision, because they will weigh it differently.
