PortBay vs MAMP / XAMPP
PortBay is an open-source (AGPL-3.0), container-free local dev manager for macOS that covers Node, PHP, and static sites with automatic HTTPS and managed DNS. MAMP (macOS, Apache, MySQL, PHP) and XAMPP (cross-platform Apache, MariaDB, PHP, Perl) are classic AMP stacks that have been the default choice for PHP local development for many years. If your team has deep familiarity with MAMP/XAMPP and you only need PHP, they still work. If you want modern HTTPS-by-default, multi-runtime support, and CLI automation, PortBay is a substantial upgrade.
At a glance
| PortBay | MAMP / XAMPP | |
|---|---|---|
| License | AGPL-3.0 (open source) | MAMP: closed (free + paid Pro) · XAMPP: Apache Friends (free) |
| Price | Free · optional Pro | MAMP: free / paid Pro · XAMPP: free |
| Containers | None (native) | None (native) |
| Runtimes | Node, PHP, static | PHP-first (Apache + PHP + MySQL) |
Local HTTPS + .test | Built in (mkcert) | Manual / limited (MAMP Pro has partial support) |
| Managed DNS | Bundled dnsmasq | None (manual /etc/hosts) |
| Reverse proxy | Caddy (automatic) | Apache (manual vhosts) |
| Footprint | Small (native) | Medium |
| Platform | macOS (Apple Silicon) | MAMP: macOS + Windows · XAMPP: cross-platform |
| Automation | CLI + MCP | Limited CLI |
What they share
All three tools are container-free and run your app processes natively on the host. All three bundle MySQL/MariaDB. All three let you serve PHP applications locally without Docker. For basic PHP + MySQL use cases, any of them can get a site running.
Where PortBay is different
PortBay was built with HTTPS-first as a default. Every project gets a real .test hostname, a mkcert certificate, and wildcard DNS via bundled dnsmasq. With MAMP or XAMPP you are typically on localhost:8888 or editing /etc/hosts manually. MAMP Pro offers some HTTPS support, but it is not the out-of-box default.
PortBay is multi-runtime. You run Node, PHP, and static sites under the same tool, each behind the same Caddy proxy, each with its own hostname. MAMP and XAMPP are Apache-centric PHP stacks; Node is outside their model.
The JSON registry makes project configuration version-controllable. The full CLI and MCP server let you automate starts, stops, and rebuilds from scripts or AI agents — none of which is possible with a GUI-only tool.
PortBay is open source. MAMP's core app is closed. XAMPP is from the Apache Friends project but is not itself open-source in the same sense as an auditable codebase under active community development.
Where MAMP / XAMPP is stronger
MAMP and XAMPP have been around for over a decade and have extensive community documentation, tutorials, and forum threads covering common issues. If you are troubleshooting an obscure PHP module or Apache config, that accumulated knowledge base is valuable.
XAMPP is cross-platform (macOS, Windows, Linux) and is a known quantity in educational and shared-team contexts. MAMP Pro offers Windows support. If your team works across operating systems and needs the same local stack on all of them today, these tools have wider OS coverage than PortBay.
For developers maintaining legacy PHP applications that depend on specific Apache behaviors or htaccess directives, MAMP/XAMPP's Apache stack is a closer match to shared-hosting production environments.
Choose MAMP / XAMPP when
- You need cross-platform parity today (Windows, Linux teammates) and cannot wait for PortBay's roadmap.
- Your application depends on Apache-specific behavior (htaccess rewrites,
.htpasswd, mod_rewrite edge cases) that differs from Caddy. - You are working in a legacy PHP environment and the existing tutorial / community ecosystem for MAMP is a genuine time-saver.
- You want a setup that a non-terminal-comfortable developer can use with no CLI knowledge.
Choose PortBay when
- You want real
.testHTTPS out of the box without editing/etc/hostsor paying for MAMP Pro. - You run Node projects alongside PHP and need one tool to manage both.
- CLI-first workflows, scripting, and MCP automation matter to you.
- Open source matters — you want to see the code and contribute.
- You want modern tooling that isn't built around Apache configuration files.
Bottom line
MAMP and XAMPP are familiar choices with years of community knowledge behind them, but they show their age when it comes to HTTPS, DNS, and multi-runtime support. PortBay is the modern, open-source path forward for macOS developers. Install PortBay and have a project running on a real .test domain in a few minutes.
