API Infrastructure

One gateway.
Every API.

Nexlayer sits between your services and the world. Auth, rate limiting, analytics, caching, and monetization — unified in a single config file your team actually understands.

Your API infra is
duct tape and prayers.

Auth in one service, rate limiting in another, analytics in a third. Every new endpoint means wiring the same middleware stack. Nexlayer collapses that into a single declarative layer that deploys in minutes.

Features

Everything between your code and the internet.

Unified Auth

JWT, API keys, OAuth2, mTLS — configure per-route. Plugs into Auth0, Clerk, or your own IdP.

Live Analytics

Request volume, latency percentiles, error rates. Real-time dashboards and Datadog/Grafana export.

Usage Metering

Track API calls per customer, enforce quotas, and pipe usage data straight to Stripe for billing.

Developer First

Config as code.
Deploy as infra.

One YAML file in your repo. Git push to deploy. No clicking through dashboards, no vendor lock-in. Nexlayer runs on your Kubernetes cluster or our managed edge.

FAQ

Common questions.

How does NexLayer differ from API gateways like Kong?

NexLayer is configured with a single YAML file and includes built-in monetization out of the box. There is no infrastructure to manage — no plugins to install, no clusters to operate. Kong is powerful but requires significant DevOps overhead. NexLayer is designed to be declared, committed, and deployed in minutes.

Can I migrate existing APIs?

Yes. NexLayer can import your existing OpenAPI specs and automatically generate a NexLayer config from them. Your routes, parameters, and auth schemes are preserved — you just add the NexLayer-specific fields you need, like rate limits and metering rules.

What authentication methods are supported?

NexLayer supports JWT, API keys, OAuth 2.0, and custom headers — configurable per route. It integrates with identity providers like Auth0, Clerk, and any OIDC-compliant IdP. You can mix auth strategies across routes in the same gateway config.

How does rate limiting work?

Rate limiting is applied per API key, per endpoint, using a sliding window algorithm for accurate enforcement. You define limits directly in your YAML config. A real-time dashboard shows current usage against quotas, and you can adjust limits without restarting the gateway.
