Zerq vs. Kong: Enterprise API Gateway Comparison
Kong is one of the most widely used API gateways and a long-time default for many teams. As requirements shift toward stricter compliance and AI agent access, enterprises are now evaluating a Kong alternative that is self-hosted and built as one unified platform.
This comparison focuses on what matters most in regulated environments: deployment flexibility, unified auditability, partner isolation, and predictable cost.
Feature comparison
| Capability | Zerq | Kong |
|---|---|---|
| Self-hosted / on-premises | ✅ Full support | ⚠️ Available (Enterprise) |
| Air-gapped deployment | ✅ Yes | ⚠️ Limited |
| Native workflow builder | ✅ Visual, no-code | ⚠️ Via plugins only |
| Developer portal | ✅ Included | ⚠️ Partial / add-on |
| Role-based access (RBAC) | ✅ Full, with separation of duties | ⚠️ Partial |
| Per-partner access control | ✅ Native | ⚠️ Complex configuration |
| Full audit trail | ✅ Included | ⚠️ Add-ons required |
| AI agent access (MCP) | ✅ Native, same gateway | ⚠️ Partial, separate path |
| Platform automation (ops) | ✅ Management MCP included | ⚠️ Not available |
| Caching and streaming | ✅ Included | ⚠️ Plugin-dependent |
| Observability (metrics + logs) | ✅ Included | ⚠️ Add-ons required |
| Predictable enterprise pricing | ✅ All-inclusive licensing | ⚠️ Plugin and module costs add up |
Where Kong works well
Kong is a strong choice for teams deeply invested in its plugin ecosystem and with the engineering capacity to configure and maintain those plugins over time. For cloud-native teams building internal microservices with lighter compliance requirements, that flexibility can be valuable.
Where Kong falls short for regulated enterprises
Audit and compliance require add-ons
Kong core does not include a compliance-grade audit trail out of the box. Teams typically combine plugins and third-party tooling to reach regulated enterprise requirements.
The developer portal is partial
The Kong Enterprise portal is functional, but advanced partner self-service patterns usually require additional setup and customization effort.
AI agent access is not unified by default
Kong provides partial MCP support, but apps and AI tools can end up on separate access and audit paths, creating operational and compliance complexity.
Plugin sprawl increases maintenance debt
Every added plugin is another component to patch, monitor, and troubleshoot. Over time this can make the platform harder to operate, not simpler.
Per-partner controls are complex to implement
Strong partner isolation requires careful setup and disciplined governance. In regulated environments, complexity in access control raises risk.
How Zerq is different
Everything is included
Workflow builder, developer portal, RBAC, audit trail, AI agent access, and observability are included in one platform instead of spread across plugins and tools.
Per-partner access is native
Partner isolation is a first-class behavior, so teams can enforce clear boundaries by default rather than assemble them from custom configuration.
One gateway for apps and AI
Apps and AI agents use the same gateway path, credential model, and audit trail. This reduces compliance gaps as AI usage grows.
Deployment flexibility without lock-in
Zerq runs on-premises, hybrid, or in your cloud with no external traffic dependency during normal operations and no proprietary lock-in requirement.
Predictable pricing
Enterprise licensing is all-inclusive, so teams avoid a growing bill tied to plugin and module sprawl.
Who should choose Kong
Kong is a fit for organizations with a strong plugin operations culture, large internal engineering bandwidth, and requirements that do not demand a single unified audit and access model across apps and AI.
Who should choose Zerq
Zerq is a fit for regulated enterprises that need built-in auditability, partner isolation, and one gateway model for both apps and AI agents without vendor lock-in.
