Caddy vs Movable Type

What Caddy is

Caddy is a web server that obtains and renews TLS certificates automatically, with a configuration file most people can read.

What Movable Type is

Movable Type is Six Apart's licensed, self-hosted content-management and publishing system. The official release history shows an active version 9 line in 2026, while the former GPL-based Movable Type Open Source program ended with the move to version 6. Deployments depend on a supported product license, server-side Perl and database components, publishing configuration, plugins and disciplined lifecycle upgrades.

What Movable Type is built to do

Structured publishing

Manages sites, entries, pages, assets and reusable templates from a central application.

Static and dynamic output

Supports publishing configurations that generate files or render selected content dynamically.

Plugin system

Extends publishing and administration, with compatibility owned by the operator and plugin vendor.

Product lifecycle

Uses documented release, maintenance, support and end-of-life phases.

Choose Caddy if

• Anyone who wants a correctly configured HTTPS server without ceremony.

Choose Movable Type if

• Existing supported Movable Type estates that need controlled upgrades
• Publishing teams whose templates and static-output model fit the platform
• Organizations able to verify licensing, regional availability and server prerequisites

Skip Movable Type if

• You require a current GPL or otherwise open-source edition
• You need vendor-operated global SaaS availability without confirming regional terms
• Your critical plugins cannot be verified on a supported release

Caddy: pros & cons

• HTTPS configured correctly by default
• Configuration is short and legible
• Single binary, easy to deploy
• Smaller community than nginx
• Fewer third-party guides
• Some advanced setups need plugins

Movable Type: pros & cons

• Active release line: Official release notes list multiple Movable Type 9 releases during 2026.
• Defined lifecycle: Six Apart publishes maintenance, support and end-of-life milestones for version planning.
• Publishing controls: The product supports managed entries, pages, assets, templates and multiple publishing approaches.
• Established upgrade guidance: Official documentation covers backups, parallel upgrade strategies and plugin compatibility checks.
• Commercial licensing: Current Movable Type is licensed software; the historical GPL MTOS program is not the current product model.
• Self-hosting complexity: Operators manage the web server, Perl modules, database, CGI or application runtime and filesystem permissions.
• Plugin upgrade risk: Critical plugins must be reinstalled and compatibility-tested against each target version.
• Regional product differences: Cloud and some release options are described as Japan-only, so availability and commercial terms need direct confirmation.
