aGo Migrator packages WordPress content (database tables + uploads + plugin and theme listings) into a single archive to move a site between environments. Lightweight alternative to enterprise migration plugins.

Features

Export site to a single archive (database, uploads).
Import archive on the destination site.
Search-replace of URLs on import.
No external services.
Fully internationalized. Translations are contributed and delivered through translate.wordpress.org.

External services

This plugin does not connect to any external service. Nothing is sent anywhere: the archive is generated and read entirely on your own server, and the plugin makes no outbound requests of its own.

The admin page does contain links that open in a new tab only when you click them. No script, style, font or image is ever loaded from any of these sites:

ago.cl, plugin documentation and the aGo Lab site (https://ago.cl/).
wordpress.org, the support forum for this plugin, the “Moving WordPress” guide and the “Changing the site URL” guide (https://wordpress.org/).
PageSpeed Insights, offered as a way to compare your site before and after a move (https://pagespeed.web.dev/).
PayPal, the voluntary donation links (https://paypal.me/).

Privacy

The plugin processes your own site data locally to build and restore the archive. It sends no data to third parties. It stores short-lived job transients and a temporary working directory in wp-content; on uninstall, those transients and the temporary directory are removed.
