Question 1

When would I choose Solo.io over Zuplo?

Accepted Answer

Solo.io is a strong choice for platform engineering teams managing complex internal microservice communication with service mesh needs. If your primary concern is east-west traffic management within Kubernetes, Solo.io is well suited. For external-facing API management with developer portals and API keys, Zuplo is the better choice.

Question 2

Does Zuplo work with Istio?

Accepted Answer

Zuplo handles external north-south API traffic and can work alongside Istio for internal east-west traffic. They serve complementary purposes in a complete API architecture.

Question 3

Does Zuplo require Kubernetes?

Accepted Answer

No. Zuplo is a fully managed SaaS with no infrastructure requirements. No Kubernetes, no Helm charts, no cluster management.

Question 4

How does the developer experience compare?

Accepted Answer

Solo.io targets platform engineers comfortable with Kubernetes manifests. Zuplo targets API developers using TypeScript and OpenAPI. Both have their place, but for shipping APIs quickly with a great developer experience, Zuplo wins.

Question 5

- question: "Do I need to be a Kubernetes expert to use Zuplo?

Accepted Answer

Solo.io (Gloo) is built on Envoy and Istio and is deeply rooted in the Kubernetes ecosystem. It requires high operational expertise. Zuplo is fully managed and serverless. You get the power of an edge gateway without ever touching a `kubectl` command.

Question 6

Is Zuplo faster to set up than Solo.io?

Accepted Answer

Setting up Solo.io involves complex Helm charts and service mesh configurations. Zuplo is plug-and-play. You can import your OpenAPI file and be live in minutes, whereas Solo.io implementations can take weeks of architectural planning.

Question 7

Does Solo.io include a built-in Developer Portal?

Accepted Answer

Solo.io focuses heavily on the gateway/ingress traffic. A developer portal is often a separate enterprise add-on or requires third-party integration. Zuplo includes a world-class developer portal by default on every plan.

Question 8

Can I extend Zuplo with TypeScript instead of Wasm?

Accepted Answer

Solo.io uses WebAssembly (Wasm) for extensions, which can be complex to build and debug. Zuplo natively runs TypeScript. It's easier to write, easier to test, and has a massive ecosystem of libraries you can use immediately.

Question 9

Is Zuplo truly serverless compared to Solo.io?

Accepted Answer

Yes. Solo.io runs on your infrastructure (or cloud clusters), meaning you pay for the idle compute. Zuplo is serverless; you don't manage the servers, and you don't pay for idle time.

Question 10

How does global latency compare?

Accepted Answer

Unless you federate Solo.io clusters across the globe (a massive operational task), your traffic is centralized. Zuplo is distributed to the edge by default. We bring the gateway to your user, drastically reducing latency for global traffic.

Question 11

Which is more affordable for startups and mid-market?

Accepted Answer

Solo.io targets the Fortune 500 with enterprise pricing. Zuplo is accessible to everyone, from solo founders to large enterprises, with a pricing model that grows with your success rather than requiring a massive upfront license.
