Question 1

Is Zuplo a replacement for Envoy as a service mesh?

Accepted Answer

No. Envoy is optimized for internal east-west traffic in microservice architectures. Zuplo is designed for north-south API traffic — the external-facing APIs your consumers interact with. They serve different purposes.

Question 2

When should I choose Envoy over Zuplo?

Accepted Answer

Choose Envoy when you need fine-grained control over internal service-to-service traffic with a service mesh like Istio. Choose Zuplo when you need a full API management layer for external APIs — with developer portals, API key management, and monetization.

Question 3

Does Zuplo require Kubernetes?

Accepted Answer

No. Zuplo is a fully managed SaaS that requires no infrastructure on your part. No Kubernetes, no control planes, no servers to patch or scale.

Question 4

How does the configuration compare?

Accepted Answer

Envoy uses protobuf configs and the xDS API — powerful but complex. Zuplo uses JSON routes and TypeScript policies that any developer can read and write. Configuration lives in your Git repo.

Question 5

- question: "Is Envoy Proxy an API gateway?

Accepted Answer

Envoy is a high-performance L7 proxy that can be used as an API gateway, but it's primarily a traffic proxy — not a full API management platform. It lacks built-in developer portals, API key lifecycle management, and monetization. Projects like Envoy Gateway and Istio add higher-level abstractions on top of Envoy, but they still focus on infrastructure concerns rather than the full API lifecycle. Zuplo provides complete API management including a developer portal, API key management, and rate limiting out of the box.

Question 6

Do I need Kubernetes to use Zuplo?

Accepted Answer

No. Zuplo is fully managed and serverless — it deploys to 300+ edge locations globally without any container orchestration. Envoy, on the other hand, is typically deployed on Kubernetes with a control plane like Istio or Envoy Gateway. If you want API management without Kubernetes overhead, Zuplo is a natural fit.

Question 7

Can Zuplo replace Envoy in a service mesh?

Accepted Answer

Zuplo is designed for external-facing API management (north-south traffic), not internal service-to-service communication (east-west traffic). If you use Envoy as part of a service mesh for internal traffic, you can keep Envoy for that and add Zuplo as the external API layer — getting developer portals, API keys, rate limiting, and monetization without replacing your mesh infrastructure.

Question 8

How does Envoy's performance compare to Zuplo?

Accepted Answer

Envoy is a high-performance C++ proxy optimized for raw throughput and low latency at the infrastructure level. Zuplo is deployed across 300+ edge locations worldwide, serving requests close to end users with low-millisecond policy execution for most operations. The performance comparison depends on your use case: Envoy excels in intra-cluster service mesh scenarios, while Zuplo's edge network provides low-latency API responses globally.

Question 9

Does Zuplo support gRPC like Envoy?

Accepted Answer

Envoy has first-class gRPC support including gRPC-JSON transcoding, gRPC-Web bridging, and HTTP/3. Zuplo focuses on HTTP-based REST and JSON APIs with WebSocket support. If gRPC is your primary protocol, Envoy is the stronger choice. Many teams use Envoy for gRPC-heavy internal services and Zuplo for their external REST APIs.

Question 10

Is Zuplo more cost-effective than running Envoy?

Accepted Answer

Running Envoy in production requires Kubernetes infrastructure, a control plane (Istio or Envoy Gateway), and operational expertise to manage upgrades, scaling, and security patches. Zuplo offers a free tier with API key management, rate limiting, and edge deployment — with no infrastructure costs. For teams without dedicated platform engineering resources, Zuplo's total cost of ownership is significantly lower.

Feature	Zuplo	Envoy Proxy
Full API Management	Complete API lifecycle management including developer portal, API key management, rate limiting, analytics, and monetization — all built in	High-performance L7 proxy focused on traffic routing, load balancing, and observability — API management features require external services
Zero Infrastructure	Fully managed SaaS — no Kubernetes, no control plane, no infrastructure to manage	Requires Kubernetes cluster + control plane (Istio, Envoy Gateway) + infrastructure management
Developer Portal	Auto-generated from OpenAPI spec with self-serve API key management and interactive docs	No built-in developer portal — requires external tooling
API Key Management	Full lifecycle with hashed storage, expiration, metadata, RBAC scopes, and self-serve portal	Not included — requires external identity provider or custom implementation
Rate Limiting	Programmable per-user, per-key, or per-API rate limits with TypeScript logic	Rate limiting requires external Redis and complex xDS filter configuration
Configuration Approach	TypeScript and JSON — familiar to any developer	Protobuf configs and xDS API — steep learning curve for API teams
Edge Performance	300+ global edge locations with <50ms latency	High performance within cluster but requires additional setup for global distribution
gRPC Support	HTTP/2 and gRPC proxying supported	Best-in-class gRPC native support
