By API7.ai Team
Last updated: July 2026
NGINX is a best-in-class web server, reverse proxy, and load balancer; Apache APISIX is a full API gateway built on NGINX/OpenResty + etcd. This guide compares them fairly — dynamic config vs reload, plugins, health checks, dashboards, and what requires the commercial NGINX Plus.
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
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. SRV (resolve + service=, in OSS since 1.27.3); registry SD via NGINX Plus or third-party |
| API management | Auth, rate limiting, transformation, canary release, full API lifecycle | Core proxy/LB; API-management behavior via njs/Lua scripting or NGINX Plus |
| Security & auth | JWT, OAuth2/OIDC, key-auth, mTLS, HMAC — plugins in the OSS core | TLS termination, mTLS, basic/subrequest auth; JWT validation via NGINX Plus or scripting |
| Observability | Prometheus, OpenTelemetry, SkyWalking, Datadog — in OSS | stub_status + logs (OSS); extended /api metrics in NGINX Plus; official Prometheus exporter |
| Protocols | HTTP/1.1, HTTP/2, HTTP/3, gRPC, WebSocket, TCP/UDP, MQTT, Dubbo | HTTP/1.1, HTTP/2, HTTP/3 (QUIC), gRPC, WebSocket, TCP/UDP (stream) |
| License & ownership | Apache-2.0; Apache Software Foundation top-level project (vendor-neutral) | BSD-2-Clause (open source); commercial NGINX Plus; owned by F5 |
When to choose Apache APISIX vs NGINX
Choose NGINX for web serving, reverse proxying, and load balancing; choose Apache APISIX when you need a full API gateway with dynamic config, plugins, and management in an open-source package.
Choose Apache APISIX if you…
- Want a full API gateway with dynamic config and no reloads
- Want 100+ open-source plugins and multi-language extensibility
- Need active health checks, a dashboard, and service discovery in OSS
- Want API lifecycle management (auth, rate limiting, canary) built in
Choose NGINX if you…
- Need a fast, lightweight web server, reverse proxy, or load balancer
- Have an existing NGINX deployment and config expertise
- Want the simplest possible single-binary proxy footprint
- (Need active health checks or a live dashboard? 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.
