Brands named, in the order the engine gave

1. Kong recommended
   Kong Konnect - The default recommendation.
2. Kong Konnect recommended
   Kong Konnect - The default recommendation.
3. Kong Gateway mentioned
   Open-source Kong Gateway underneath means you can self-host a client's data plane in their cloud while you keep the control plane, which is the single most useful property for agency work.
4. Zuplo mentioned
   (Zuplo TCO analysis (https://zuplo.com/learning-center/the-true-cost-of-kong-tco-analysis), Vendr (https://www.vendr.com/marketplace/kong))
5. Tyk mentioned
   Tyk - The best answer when clients demand self-hosting or data residency.
6. Azure mentioned
   Azure API Management - Pick this whenever the client is already a Microsoft shop;
7. Entra ID mentioned
   the Entra ID integration and procurement path sell themselves.
8. Stripe mentioned
   Edge deployment across 300+ PoPs, config-as-code in TypeScript with GitOps deploys, and - the part agencies care about - built-in API key management and monetization/billing, so you can hand a client a working paid API without wiring Stripe yourself.
9. Gravitee mentioned
   Gravitee - Worth a look specifically because it ships an explicit multi-tenancy deployment mode rather than making you assemble one, and it handles event-native APIs (Kafka, MQTT, webhooks) that the others treat as second-class.
10. AWS mentioned
    Amazon API Gateway - Not a full lifecycle platform, but if the client's workload already lives in AWS, usage plans + API keys give you per-tenant throttling and quotas at near-zero fixed cost.
11. Cloudflare mentioned
    Cloudflare Workers for Platforms - The outlier pick, and the right one if you're shipping client-specific logic rather than proxying existing backends.

The answer, as recorded

For an agency - where the real constraints are multi-tenancy, per-client metering/billing, white-labeled developer portals, and not eating a five-figure floor before your first client pays - here's how I'd rank them: **1. Kong Konnect** - The default recommendation. Konnect's control planes + workspaces model maps cleanly onto "one client per workspace," with RBAC so client staff can see their own APIs and nothing else. Open-source Kong Gateway underneath means you can self-host a client's data plane in *their* cloud while you keep the control plane, which is the single most useful property for agency work. Downside is cost: Plus is roughly $105/mo per gateway service with 1M requests included and ~$200 per additional million, and it climbs fast. ([Zuplo TCO analysis](https://zuplo.com/learning-center/the-true-cost-of-kong-tco-analysis), [Vendr](https://www.vendr.com/marketplace/kong)) **2. Tyk** - The best answer when clients demand self-hosting or data residency. Fully open-source gateway, genuinely usable without a license, and the licensed tier adds SSO and fine-grained RBAC. Tyk also shipped native MCP gateway support, which matters if clients are exposing APIs to AI agents. Pricing is quote-based, so negotiate an agency/reseller arrangement rather than per-client contracts. ([Zuplo AI gateway comparison](https://zuplo.com/learning-center/ai-gateway-comparison-mcp-a2a-agent-governance)) **3. Azure API Management** - Pick this whenever the client is already a Microsoft shop; the Entra ID integration and procurement path sell themselves. The v2 tiers made it viable for smaller engagements: Basic v2 ~$150/unit/month with 10M requests included, Standard v2 ~$700/unit/month with 50M and VNet integration. Microsoft publishes a reference architecture for tenant-mapped routing, so per-client isolation is a solved problem. ([Microsoft Learn](https://learn.microsoft.com/en-us/azure/api-management/v2-service-tiers-overview), [apim-multitenant](https://github.com/fsaleemm/apim-multitenant)) **4. Zuplo** - Strongest fit for small, fast client builds. Edge deployment across 300+ PoPs, config-as-code in TypeScript with GitOps deploys, and - the part agencies care about - built-in API key management and monetization/billing, so you can hand a client a working paid API without wiring Stripe yourself. Caveat worth stating plainly: a large share of the 2026 "best of" comparison content ranking Zuplo first is published by Zuplo, so discount the rankings and evaluate the product. ([Zuplo](https://zuplo.com/learning-center/best-api-management-platforms-2026)) **5. Gravitee** - Worth a look specifically because it ships an explicit multi-tenancy deployment mode rather than making you assemble one, and it handles event-native APIs (Kafka, MQTT, webhooks) that the others treat as second-class. Good when a client's "API" isn't purely REST. ([Gravitee docs](https://documentation.gravitee.io/apim/installation-and-upgrades/install-gravitee-api-management/multi-tenancy)) **6. Amazon API Gateway** - Not a full lifecycle platform, but if the client's workload already lives in AWS, usage plans + API keys give you per-tenant throttling and quotas at near-zero fixed cost. AWS documents the custom-tenant-ID pattern for exactly this. Use it for individual client builds, not as your agency-wide standard. ([AWS Compute Blog](https://aws.amazon.com/blogs/compute/managing-multi-tenant-apis-using-amazon-api-gateway)) **7. Cloudflare Workers for Platforms** - The outlier pick, and the right one if you're shipping client-specific logic rather than proxying existing backends. Dispatch traffic to per-customer Workers, set per-tenant limits, meter every request for billing - no per-client infrastructure at all. ([Cloudflare](https://www.cloudflare.com/solutions/platforms/)) Two I'd steer you away from: **Apigee** and **MuleSoft**. Both are excellent enterprise platforms and both are wrong for an agency - Apigee's environment-based pricing puts mid-sized deployments at $50K-$120K/year, and you'd be absorbing that per client. Recommend them *to* clients with that budget; don't standardize on them. ([Zuplo gateway pricing comparison](https://zuplo.com/learning-center/api-gateway-pricing-comparison-2026)) One structural note: the biggest decision isn't the vendor, it's whether you run one shared tenancy with per-client workspaces (cheaper, faster onboarding, but you own the blast radius and the exit story gets awkward when a client leaves) or separate instances per client (clean handoff, clean billing, higher fixed cost). Kong and Gravitee let you start with the first and migrate individual clients to the second; Zuplo and Azure v2 make the second cheap enough to just start there.
