This guide compares them fairly — dynamic config vs reload, plugins, health checks, dashboards, and what requires the commercial NGINX Plus. TL;DR NGINX (open source) is a best-in-class web server, reverse proxy, and load balancer. Apache APISIX is a full API gateway built on NGINX/OpenResty + etcd that adds dynamic configuration, 100+ plugins, API management, and a dashboard — all Apache-2.0. Several API-gateway-grade runtime features that require the commercial NGINX Plus are open-source in APISIX. - A fast web server, reverse proxy, or load balancer: NGINX - A full API gateway with dynamic config, plugins, and a dashboard: Apache APISIX - NGINX's proven core plus API-gateway features, open-source: Apache APISIX - [At a glance](#at-a-glance) - [What is APISIX?](#what-is-apisix) - [What is NGINX?](#what-is-nginx) - [Architecture](#architecture) - [Feature comparison](#feature-comparison) - [When to choose](#choose) - [FAQ](#faq) ## Apache APISIX vs NGINX at a glance They solve different layers: NGINX is the web server / reverse proxy / load balancer; APISIX is a full API gateway built on top of it, adding dynamic config, plugins, and management features that otherwise need scripting or NGINX Plus. | Dimension | Apache APISIX | NGINX | | -------------------- | ------------------------------------------------------- | --------------------------------------------------------------- | | Primary role | Full API gateway (built on NGINX/OpenResty + etcd) | Web server, reverse proxy, and load balancer | | Config model | ✓ Dynamic via etcd — no reload | Static config + graceful reload (NGINX Plus adds a runtime API) | | Plugins | 100+ hot-loadable plugins (Lua, Go, Java, Python, Wasm) | C modules, njs, Lua/OpenResty — no hot-loadable plugin catalog | | Active health checks | ✓ In open source | NGINX Plus only (OSS is passive) | | Built-in dashboard | ✓ Open-source dashboard | NGINX Plus only | | License & owner | Apache-2.0 — Apache Software Foundation | BSD-2-Clause (OSS) + commercial NGINX Plus — F5 | ## What is Apache APISIX? Apache APISIX is an Apache-2.0 API gateway built on NGINX/OpenResty with an etcd config store, adding dynamic configuration, 100+ plugins, API management, and a dashboard. Apache APISIX is a full API gateway built on NGINX/OpenResty (LuaJIT) with an etcd configuration store. It adds dynamic configuration, 100+ hot-loadable plugins, API lifecycle management, and a dashboard on top of NGINX’s proven proxying core — all under Apache-2.0, governed by the Apache Software Foundation. Core NGINX/OpenResty (LuaJIT) + etcd License Apache-2.0 (ASF top-level project) Best for A full, dynamic, open API gateway ### Pros - Dynamic config via etcd — routes, plugins, upstreams apply with no reload - 100+ open-source plugins in Lua, Go, Java, Python, or WebAssembly - Active health checks, dashboard, and service discovery in open source - Full API lifecycle: auth, rate limiting, transformation, canary - Vendor-neutral Apache-2.0 governance ### Cons - A gateway, not a general-purpose web server (it runs on NGINX under the hood) - More moving parts than a single nginx.conf (etcd to operate) - Smaller commercial-support footprint than F5/NGINX (API7 provides it) ## What is NGINX? NGINX is a high-performance open-source web server, reverse proxy, and load balancer (BSD-2-Clause, owned by F5). NGINX Plus is the commercial edition adding runtime APIs, active health checks, and a live dashboard. NGINX is a high-performance, widely deployed open-source web server, reverse proxy, and load balancer (BSD-2-Clause), owned by F5. NGINX Plus is the commercial edition that adds runtime configuration APIs, active health checks, a live dashboard, and more. Apache APISIX is itself built on NGINX/OpenResty. Role Web server / reverse proxy / LB License BSD-2-Clause (OSS) + commercial Plus Best for Fast web serving, proxying, load balancing ### Pros - Best-in-class, extremely efficient web server, reverse proxy, and LB - Graceful, zero-downtime config reloads - Broad protocols: HTTP/1.1, HTTP/2, HTTP/3 (QUIC), gRPC, WebSocket, TCP/UDP - Extensible via dynamic C modules, njs (JavaScript), and Lua/OpenResty - Huge install base, mature, well-documented ### Cons - Not an API gateway out of the box — API management needs scripting or NGINX Plus - Open-source applies route/upstream changes by reload (no runtime API) - Active health checks, live dashboard, runtime upstream API are NGINX Plus only - No hot-loadable, config-driven plugin ecosystem ## Architecture: built on NGINX, configured dynamically APISIX runs on the same NGINX/OpenResty core as NGINX, but replaces static-file-plus-reload configuration with an etcd-backed dynamic model, and adds a hot-loadable plugin runtime. Apache APISIX is built on NGINX and ngx\_lua (OpenResty/LuaJIT), so it inherits NGINX's proven event-driven proxying. On top of that it stores configuration in etcd and applies route, upstream, and plugin changes dynamically — with no reload — and loads plugins at runtime. That is the core architectural difference from running NGINX directly. With open-source NGINX, configuration lives in static files and is applied with a graceful, zero-downtime reload (new workers start, old workers drain) — there is no runtime API to add or remove upstreams in the open-source edition (NGINX Plus adds one, plus a key-value store). NGINX remains extensible through dynamic C modules, the njs JavaScript module, and Lua via OpenResty; what it lacks is APISIX's config-driven, hot-loadable plugin ecosystem. That graceful reload is not free at API-gateway change frequency, though. Every reload starts a full new set of worker processes while the old set lingers to drain in-flight and long-lived connections — WebSocket sessions and gRPC streams can pin old workers for a long time — so memory briefly doubles and frequent route changes turn into constant worker churn. A gateway whose routes, upstreams, and plugins change many times a day is exactly the workload where per-change reloads become operationally heavy — and why APISIX applies changes through etcd with no reload at all. ## Apache APISIX vs NGINX: feature comparison The two share an NGINX core. APISIX adds dynamic config, a plugin runtime, active health checks, a dashboard, and service discovery in open source — several of which require NGINX Plus on the NGINX side. | Feature | Apache APISIX | NGINX | | -------------------- | ------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------- | | Primary role | Full API gateway built on NGINX/OpenResty (LuaJIT) + etcd | High-performance web server, reverse proxy, and load balancer | | Config & propagation | Dynamic via etcd — routes, plugins, and upstreams apply with no reload | Static config files applied by a graceful, zero-downtime reload; NGINX Plus adds a runtime upstream API + key-value store | | Extensibility | 100+ hot-loadable plugins; Lua, Go, Java, Python, WebAssembly | C modules (static/dynamic), njs (JavaScript), Lua via OpenResty — no hot-loadable plugin catalog | | Health checks | ✓ Active and passive in the open-source core | Passive in open source; active health checks require NGINX Plus | | Dashboard | ✓ Open-source dashboard (apache/apisix-dashboard) | No dashboard in OSS; live-activity dashboard in NGINX Plus | | Service discovery | Built-in: Kubernetes, Consul, Consul KV, Nacos, Eureka, DNS | DNS-based incl.

That is NGINX Plus.) **Bottom line:** NGINX is an excellent web server and reverse proxy — and APISIX is built on it. If you need a full API gateway (dynamic configuration with no reloads, 100+ plugins, active health checks, a dashboard, and service discovery) without stepping up to the commercial NGINX Plus, Apache APISIX delivers those in an Apache-2.0 package.

NGINX (open source) is a high-performance web server, reverse proxy, and load balancer. Apache APISIX is a full API gateway built on NGINX/OpenResty with an etcd configuration store, adding dynamic configuration, 100+ plugins, API lifecycle management, and a dashboard on top of NGINX’s proxying core. In short, APISIX is a gateway built on NGINX, not a replacement for NGINX as a web server. ### Does NGINX have downtime when you reload config? No. \`nginx -s reload\` is graceful and zero-downtime: NGINX starts new worker processes, then shuts old ones down only after they finish serving in-flight connections. At API-gateway change frequency it still carries real operational cost: each reload spins up a full new worker set while old workers linger to drain long-lived connections (WebSockets, gRPC streams), briefly doubling memory. Apache APISIX applies route and upstream changes dynamically through etcd with no reload at all. ### Is NGINX extensible without NGINX Plus? Yes. Open-source NGINX is extensible via C modules (static or dynamic), the official njs JavaScript module, and Lua through OpenResty (the same LuaJIT foundation APISIX is built on). What it does not have is a hot-loadable, config-driven plugin catalog — APISIX ships 100+ plugins that load dynamically and can be written in Lua, Go, Java, Python, or WebAssembly. ### What requires NGINX Plus that Apache APISIX includes for free? Several API-gateway-grade runtime features are NGINX Plus (commercial) only: active health checks, the live-activity dashboard, the runtime upstream-configuration API, and the key-value store. Apache APISIX provides active health checks, a dashboard, dynamic configuration, and service discovery in its open-source (Apache-2.0) distribution. ### Is Apache APISIX faster than NGINX? Both build on the same NGINX/OpenResty core, so raw proxying performance is comparable. Apache APISIX self-reports a single-core throughput of about 18,000 QPS at under 0.2 ms average latency. APISIX adds gateway features (routing, plugins, auth) on top, so compare like-for-like configurations and benchmark your own workload. ### Can Apache APISIX replace NGINX? For API gateway, ingress, and reverse-proxy use cases, APISIX can replace a hand-configured NGINX and add dynamic config, plugins, and a dashboard. For pure web-serving or static-content use cases, NGINX remains an excellent, lightweight choice — and APISIX itself runs on NGINX under the hood. ## Related comparisons [Apache APISIX vs Kong](https://api7.ai/apisix-vs-kong) · [Kong vs Traefik](https://api7.ai/kong-vs-traefik) · [All gateway comparisons](https://api7.ai/api-gateway-comparison) ## Ready to get started?
