Joomla! Downloader is a smart, single-file PHP script that revolutionizes the Joomla! installation process. Built to save time and simplify deployment, it automatically downloads and installs the latest version of Joomla! directly on your server with just one click - no FTP uploads, no manual downloads, no waiting.
Perfect for site administrators, developers, and testers who want to save time and have instant access to all Joomla! versions including stable releases, release candidates, and nightly builds directly from official Joomla! update servers.
The traditional Joomla installation process is time-consuming and involves multiple manual steps:
- Visit the Joomla website to check the latest version
- Download the package to your local computer
- Wait for the download to complete
- Extract the ZIP file locally
- Upload hundreds of files via FTP to your server
- Wait for the upload to complete (can take several minutes)
With Joomla! Downloader, all these steps are replaced by a single click! The script:
- Automatically downloads the latest version directly from Joomla's official servers to your hosting server
- Extracts the files instantly on your server
- Eliminates slow FTP uploads
- Reduces installation time from 15-30 minutes to less than 1 minute
- Guaranteed latest version: The script automatically fetches the most recent Joomla release from official update servers
- No manual checking needed: Forget about visiting the Joomla website to verify versions
- Automatic version detection: The script displays all available versions with detailed information (PHP requirements, database compatibility, release date)
- Update notifications: Built-in version checker that alerts you when a new version of the downloader script is available
