Apache HTTP Server and nginx are the safest general choices. Choose Apache when you need its extensive module ecosystem and familiar per-directory rules; choose nginx when your priority is an efficient edge reverse proxy, cache, or load balancer. Caddy favors simple, Go-based deployments, lighttpd targets low-resource systems, OpenLiteSpeed offers a GPLv3 high-performance option, and Cherokee is best treated as a legacy or research project until its current maintenance is verified.
This guide compares all six by configuration, application support, proxying, protocols, resource behavior, licensing, platform fit, and maintenance signals, then gives a practical selection and deployment checklist.
At-a-glance comparison
| Server | Best fit | Configuration style | Proxy/cache/load balancing | Protocol notes | License | Maintenance signal |
|---|---|---|---|---|---|---|
| Apache HTTP Server | Feature-rich general-purpose hosting | Text configuration, virtual hosts, optional per-directory rules | Built in through modules | TLS/SSL and HTTP/2 documented | Apache License 2.0 | Active 2.4 line; 2.4.68 released 2026-06-08 |
| nginx | Edge proxying, caching, and high connection counts | Central text configuration | Core reverse proxy, cache, and load-balancer roles | TLS SNI, HTTP/2, and HTTP/3 documented | 2-clause BSD | Established project; verify package version for your platform |
| Caddy | Teams wanting a Go-based, extensible server | Streamlined configuration; exact current syntax should be checked in official documentation | Candidate for proxy deployments; current feature set requires verification | Verify current protocol support before committing | Apache license (overview) | Check current release and support activity directly |
| lighttpd | Speed-sensitive or resource-constrained systems | Lightweight text configuration | Use where its documented modules meet your proxy needs | Confirm required HTTP versions in the release you deploy | BSD | Verify current release and maintenance status |
| OpenLiteSpeed | High-performance serving with GPLv3 licensing | Its own configuration model; not automatically Apache-compatible | Reverse proxy support documented | HTTP/2 and HTTP/3 supported | GPLv3 | Open-source edition of LiteSpeed Web Server Enterprise |
| Cherokee | Legacy installations or research | Graphical administration interface | Reverse proxy capability identified in the overview | Current protocol support not established here | GPL | Last listed release date 2013-04-21; treat as a maintenance warning |
What an open-source web server does
A web server accepts client connections, selects a virtual host, serves static files, and commonly forwards dynamic requests to an application runtime. Modern servers also terminate TLS, compress or cache responses, enforce headers, distribute traffic among backends, and expose logs and metrics. “Fastest” therefore depends on the workload: a static file benchmark, a TLS-heavy API, and a proxy handling thousands of idle connections stress different parts of the stack.
Compare the candidates on configuration and learning curve, extension ecosystem, static and dynamic request handling, reverse proxy and cache behavior, HTTP/2 or HTTP/3 needs, memory and connection behavior, license obligations, platform support, documentation, and current maintenance. A small static site may value low overhead, while a multi-tenant application may value modules, isolation, and operational familiarity more.
#1 Best Overall
1. Apache HTTP Server (httpd)
Why teams choose it
Apache is the broadest generalist in this group. The project describes it as “A fast, reliable, and extensible open-source web server for modern operating systems.” Its 2.4 line supports virtual hosts, dynamic modules, TLS/SSL, HTTP/2, caching, reverse proxying, load balancing, and more than 100 modules. That breadth lets one installation serve static assets, proxy application servers, enforce authentication, and apply specialized request rules.
Configuration and operations
Apache’s text configuration and per-directory controls are familiar to many hosting administrators. Virtual-host blocks make it straightforward to separate domains, certificates, logs, and document roots. Dynamic modules let you add only the capabilities you need, but the large choice also increases the chance of conflicting settings or forgotten modules. Establish a minimal baseline, keep site rules in version control, and test a configuration before every reload.
Current release and license
The project lists Apache HTTP Server 2.4.68, released 2026-06-08 by the Apache Software Foundation. Apache software is distributed under Apache License 2.0, which is generally permissive; still review the license notice and attribution requirements for your distribution and bundled modules.
Best use
Pick Apache for teams that already know its configuration model, need its module ecosystem, or rely on per-directory behavior supplied by existing applications. It is also a sensible default for conventional shared or virtual-hosted environments.

2. nginx
Why teams choose it
nginx (“engine x”) is an HTTP web server, reverse proxy, content cache, load balancer, TCP/UDP proxy server, and mail proxy server. Its event-oriented architecture is commonly used at the edge, where many connections may wait on network or upstream activity. It can terminate TLS, serve static files, cache responses, and pass dynamic requests to FastCGI, uWSGI, or SCGI applications.
Protocol and traffic features
nginx documents TLS SNI, HTTP/2, HTTP/3, caching, and fault-tolerant load balancing. That combination makes it a strong front door for several application servers or containers. Separate edge policy from application code: define timeouts, body-size limits, health checks, cache rules, and trusted proxy headers explicitly, then log both client and upstream status.
Trade-offs
nginx uses a centralized configuration model rather than Apache-style per-directory overrides. This is predictable for operations teams but means application owners cannot usually drop local rule files into a document tree and expect them to be honored. Validate directive scope and inheritance carefully; a syntactically valid setting in the wrong block can silently miss the requests you intended to change.
Best use
Choose nginx when reverse proxying, caching, load balancing, or large numbers of concurrent connections are central requirements. It is also an effective static-file server when you want a small, focused edge configuration.

3. Caddy
Why it is considered
Caddy is a cross-platform, extensible server written in Go and identified in the available overview as open source under an Apache license. A Go implementation can be attractive when your team prefers a single portable binary and an extension model aligned with Go tooling.
What to verify before production
The material available for this comparison does not establish Caddy’s current version, exact feature set, or present protocol defaults. Confirm the release, TLS behavior, HTTP/2 or HTTP/3 support, plugin compatibility, configuration syntax, and upgrade policy in Caddy’s official documentation for the date and platform you will deploy. Do not infer those details from an older tutorial.
Best use
Caddy is a candidate for teams that value a Go-based, extensible server and are willing to standardize on its current documented workflow. Make a small proof-of-concept first if you depend on specialized proxy modules or legacy configuration conventions.
4. lighttpd
Why it is considered
lighttpd is a lightweight open-source server aimed at speed-critical environments and low resource use. Its appeal is a small operational footprint when the workload is primarily static content or a narrowly defined service.
Quick wins for a faster PC:

The available overview identifies lighttpd as BSD licensed but does not establish a current version or maintenance status. Check the project’s official site for release activity, supported operating systems, TLS libraries, HTTP versions, proxy modules, and security-advisory process before selecting it for a new public service.
Best use
Use lighttpd when memory and CPU budgets are tight, the request path is simple, and the modules you need are confirmed for your chosen release. Avoid choosing it solely from an old benchmark; measure your own files, TLS settings, and concurrency pattern.
5. OpenLiteSpeed
Why it is considered
OpenLiteSpeed (OLS) is the open-source edition of LiteSpeed Web Server Enterprise. Its repository states that users may download, use, distribute, and modify it under GPLv3. Official documentation identifies HTTP/2 and HTTP/3 support, and the support FAQ says OLS can act as a reverse proxy.
Configuration compatibility
OLS does not automatically read and use Apache configuration files in the way LiteSpeed Enterprise does. Treat migration as a configuration project: inventory rewrite rules, virtual hosts, PHP or other application handlers, certificates, headers, and proxy routes; then recreate and test them in OLS’s configuration model rather than copying files and assuming equivalent behavior.
Rank #3
Best use
Choose OLS when GPLv3 is acceptable, HTTP/2 or HTTP/3 matters, and you want a high-performance server with LiteSpeed lineage. Validate every Apache-dependent integration during a staged migration.
6. Cherokee
Why it is notable
Cherokee is a lightweight open-source web server and reverse proxy with a graphical administration interface. The comparison material lists it as GPL licensed and shows a last listed release date of 2013-04-21.
Maintenance warning
That old release date is a serious production risk. Current security fixes, operating-system compatibility, TLS libraries, and HTTP protocol support are not established here. Treat Cherokee as a legacy or research option until you independently confirm active maintenance, current packages, and a credible upgrade path. Do not expose an unmaintained build to the public internet merely because its configuration UI is convenient.
How to choose
Choose Apache when ecosystem breadth wins
Select Apache for mature module coverage, virtual hosts, and per-directory rules. It is usually the least disruptive choice for applications whose deployment instructions already assume httpd.

Select nginx for reverse proxying, caching, load balancing, or a large population of concurrent connections. Keep application behavior in the backend and edge policy in one reviewed nginx configuration.
Choose Caddy after verifying today’s documentation
Select Caddy when a Go-based, extensible server fits your team, but pin a documented release and test required protocol and plugin behavior first.
Choose lighttpd for constrained systems
Select lighttpd for a measured low-resource workload with a small feature set and confirmed current maintenance.
Choose OpenLiteSpeed for GPLv3 plus modern protocols
Select OLS when its GPLv3 terms and configuration model fit, and when HTTP/2 or HTTP/3 and reverse proxying are priorities.
Choose Cherokee only with a verified legacy reason
For a new production deployment, the 2013 release signal should disqualify Cherokee unless you can demonstrate current maintenance and an isolation plan.
Deployment checklist
- Define the traffic path. Decide whether the server serves files directly, proxies one application, or balances several backends.
- Record hard requirements. List TLS versions, HTTP/2 or HTTP/3 needs, WebSocket or streaming behavior, upload limits, cache rules, authentication modules, and log format.
- Pin a supported release. Use your operating system’s security channel or the project’s documented packages; record the exact version and rollback package.
- Build a minimal configuration. Start with one hostname, one certificate, one health endpoint, and only the modules or directives required.
- Test before exposure. Check redirects, certificate names, compressed and uncompressed assets, large uploads, application errors, upstream timeouts, and graceful reloads.
- Observe the system. Keep access and error logs, upstream latency, status codes, open connections, memory, and file-descriptor usage. Set alerts for certificate expiry and repeated upstream failures.
- Plan upgrades. Read release notes, stage the new build, retain the prior package and configuration, and rehearse a rollback.
Common problems and fixes
502 or 504 responses from a reverse proxy
Confirm the backend is listening on the address and port configured in the proxy, that the firewall allows the connection, and that the proxy timeout exceeds the application’s legitimate response time. Inspect both proxy and application logs; increasing a timeout will not fix a crashed or unreachable backend.
Correct site serves the wrong certificate
Check hostname matching, SNI behavior, certificate-chain order, and which virtual host is the default. Test each hostname separately and reload only after configuration validation succeeds.
Static files return 403 or 404
Verify the document root, URL-to-file mapping, directory permissions, and execute permission on every parent directory. A valid file can still be inaccessible if the service account cannot traverse its path.
Configuration changes appear ignored
Confirm you edited the active include file, ran the server’s syntax check, and performed a graceful reload rather than only saving the file. Log the running process’s version and configuration path during deployment.
HTTP/3 is unavailable
Do not assume a protocol name in a tutorial equals support in your package. Verify that your selected server, build, TLS library, listener, firewall, and client all support the required protocol; otherwise provide HTTP/2 or HTTP/1.1 as an intentional fallback.
Migration from Apache behaves differently on OpenLiteSpeed
Recreate the configuration in OLS rather than copying Apache files. Test rewrite rules, handlers, authentication, headers, and proxy routes individually because OLS does not automatically consume Apache configuration the same way LiteSpeed Enterprise does.

Cost, capacity, and reliability notes
The server license is only one part of operating cost. Budget for compute, storage, TLS certificate management, backups, CDN or reverse-proxy services, and uptime monitoring. Capacity planning should use your own request mix and concurrency: measure static and dynamic paths separately, include TLS handshakes and cache misses, and leave headroom for deploys and traffic spikes. A clean configuration, reproducible releases, health checks, and tested rollback usually improve reliability more than switching servers on the basis of an undated benchmark.

Can I run Apache and nginx together?
Yes. A common pattern is nginx at the edge for TLS, caching, or load balancing with Apache behind it for application-specific modules. Define which layer owns redirects, compression, and client-IP headers so the two configurations do not conflict.
Is HTTP/3 required for a normal website?
No. Use it when your clients, network, and server build support it and testing shows a benefit. Keep a correctly configured HTTP/2 or HTTP/1.1 fallback.
Does an open-source license mean hosting is free?
The software license does not remove infrastructure costs such as compute, bandwidth, storage, certificates, monitoring, and administration.
What should I check before adopting an older server?
Confirm recent releases, security advisories, supported operating systems and TLS libraries, package availability, documentation quality, and a rollback path. Cherokee’s 2013-04-21 release signal requires this scrutiny.
