Open source alternative to Kong Konnect, AWS API Gateway and Zuplo
Last verified
Manage API keys, deploy APIs, and control gateway traffic from one platform covering auth, rate limits, and real-time observability.
Teams shipping APIs to external developers get key issuance, usage tracking per key, rate limiting, and access revocation from one service rather than building it themselves. The gateway layer handles auth checks before traffic reaches application code.
Your API uses OAuth or JWT-based auth exclusively. Unkey's key management is designed for API key flows; it does not replace an OAuth2 authorization server.
Startups running separate hosting, gateway, and observability vendors can consolidate onto Unkey and reduce the number of dashboards, billing accounts, and integration points. The Git-based deploy flow fits teams already using GitHub or GitLab.
Your stack is fully standardized on AWS services. Unkey is a different deployment model; migrating from a fully AWS-native setup adds migration cost that may outweigh consolidation gains.
Companies whose product exposes an API to paying customers can use Unkey's per-key rate limiting, usage analytics, and upcoming developer portal to manage customer-tier access controls without building key infrastructure from scratch.
You need a feature-complete developer portal today. The self-serve portal is listed as coming soon and is not yet available.
Teams that issue API keys to third parties and need hard security guarantees can rely on Unkey's globally consistent key verification and instant revocation. A compromised key stops working across all regions immediately, without waiting for cache expiration.
Your security model relies on short-lived JWT tokens with automated rotation. Unkey's revocation model is built for longer-lived API keys, not sub-minute token lifecycles.
Building and operating APIs at scale requires assembling multiple services from different vendors: a hosting provider, an API gateway, a key management service, a rate limiter, and an observability stack. Each adds its own dashboard, billing, configuration format, and failure mode. Teams spend significant time integrating these tools instead of building their product.
The specific pain compounds at the boundary points. API keys issued in one system need to match rate limits enforced in another, while observability data lives in a third. When something breaks, debugging requires correlating logs across unrelated dashboards. As traffic grows, each vendor charges separately, and cost prediction becomes difficult across the fragmented stack.
Issue, verify, revoke, and set permissions on API keys through a global verification layer. Keys support per-key rate limits, RBAC roles, and fine-grained access scopes. Revocation takes effect immediately across all regions without waiting for cache expiration.
Connect a Git repository and Unkey deploys automatically on every push. Each commit gets a preview environment for testing before promotion to production. Rollbacks switch back to the previous production instance in seconds; the prior version stays running for 30 minutes after a deploy.
Route requests through globally distributed gateways that enforce auth, rate limits, and request validation close to end users. The gateway handles OpenAPI schema checks, flagging breaking changes before they reach production. Edge enforcement reduces round-trip latency versus centralizing these checks in application code.
Set rate limits per IP, user, or API key and enforce them at the edge. The system maintains globally consistent state across regions, so distributed clients cannot bypass limits by hitting different entry points. Limit violations are logged automatically alongside other request events.
Every request is logged automatically: verifications, rate limit decisions, audit events, and HTTP request/response pairs, without adding custom instrumentation. Filter by deployment, region, user, or custom tag to trace issues through the dashboard, or query verification data over the HTTP API from external systems.
AWS API Gateway is AWS's managed HTTP gateway service, handling routing, authorization via IAM and Lambda authorizers, and throttling. Application deployment runs separately through Lambda, EC2, or App Runner.
| Feature | Unkey | AWS API Gateway |
|---|---|---|
| License | FSL-1.1-ALv2 | Proprietary |
| Self-hosting | Yes | No (managed only) |
| API key management | Full lifecycle: issue, revoke, RBAC | Basic (usage plan keys) |
| Deployment | Built-in | Separate AWS services required |
| Observability | Built-in request logging | Requires CloudWatch setup |
Unkey suits teams that want deployment, gateway, and key management in one product without AWS ecosystem dependencies. AWS API Gateway remains the right choice for teams invested in AWS who need native Lambda triggers, IAM policy-based authorization, or tight CloudWatch integration.
Kong Konnect is the managed version of Kong's API gateway, covering routing, plugin-based auth, rate limiting, and traffic shaping. It does not include application deployment.
| Feature | Unkey | Kong Konnect |
|---|---|---|
| License | FSL-1.1-ALv2 | Proprietary |
| Self-hosting | Yes | No (Konnect is managed) |
| Deployment | Built-in | Not included |
| API key management | Full lifecycle | Via Kong plugins |
| Observability | Built-in | Via Kong plugins |
Unkey is a better fit when you want one product that handles both deployment and gateway. Kong Konnect is the stronger choice for teams with complex traffic routing needs or existing Kong investments.
Zuplo is a developer-oriented gateway platform with built-in OpenAPI-based documentation and a developer portal. It focuses on the gateway layer without application deployment or self-hosting.
| Feature | Unkey | Zuplo |
|---|---|---|
| License | FSL-1.1-ALv2 | Proprietary |
| Self-hosting | Yes | No |
| Deployment | Built-in | Not included |
| Developer portal | In development | Yes (included) |
| OpenAPI support | Validation on deploys | Documentation generation |
Zuplo is the better pick when a developer portal is a current requirement, since Unkey's portal is still in development. Unkey is the stronger choice for teams that need self-hosting, built-in deployment, and deeper API key lifecycle management.
Yes. Unkey is source-available under the Functional Source License 1.1 (FSL-1.1-ALv2), which explicitly permits self-hosting for any Permitted Purpose including internal commercial use. You cannot use it to run a competing managed service, but running it on your own infrastructure for your own APIs is within the license terms. The code relicenses to Apache 2.0 two years after each version's release.
AWS API Gateway handles routing and basic authorization but does not include API key lifecycle management, developer-facing usage analytics, or application deployment. Unkey combines gateway functions with deploy pipelines, per-key analytics, and instant key revocation in one control plane. AWS API Gateway remains a stronger choice when you are already invested in AWS infrastructure and need native Lambda triggers, IAM policy-based authorization, or CloudWatch integration.
Not currently. As of late 2026, Unkey has paused external pull requests while the core team focuses on platform stability and direction. The repository remains public and forkable under the FSL-1.1-ALv2 license. Bug reports and feature requests are accepted via GitHub Issues.
The deployment platform supports Docker containers running any language or runtime. Unkey's own codebase is written in Go, but your API can use any stack that packages as a Docker image. The HTTP-based gateway and key verification API are callable from any language with an HTTP client.
Unkey is source-available, not OSI-certified open source. The code is public and forkable, but the Functional Source License 1.1 (FSL-1.1-ALv2) restricts use: you may run it internally, modify it, and redistribute it, but you cannot offer it as a competing managed service or SaaS. Each version relicenses to Apache 2.0 two years after its release date.
