What it does
WeBuilder is a desktop code editor for maintaining web projects in HTML, CSS, JavaScript, PHP and related languages. It combines syntax highlighting and completion with project search, code navigation, validators, a browser preview and FTP/SFTP/FTPS tools. PHP workflows can also use its syntax checks and xDebug debugger. It is aimed at web developers who want project and publishing tools in the same Windows editor.
Keep web files and project tools together
Start with a project and open its HTML, CSS, JavaScript or PHP files in WeBuilder. The official feature list describes language-aware completion, code navigation, reusable snippets, folding and a minimap. For a page change, use the HTML/CSS validators or the JavaScript and PHP checks documented on the product page, then preview the result in a browser. PHP users can also configure the listed xDebug debugger.
For a site that is already hosted, the built-in file browser can connect through FTP, SFTP or FTPS; the product guide also lists publishing changed project files. This keeps editing and deployment in one desktop tool, although it is not a general-purpose build server or a replacement for the project's runtime.
The current download page lists Windows 10 and 11. The purchase page separates general-use and personal, non-commercial licenses and includes free updates to the current major version; the home page describes the license as a one-time fee. Exact local totals can depend on license type and applicable taxes. WeBuilder is one of several Blumentals products, so choose the WeBuilder listing rather than its narrower Rapid PHP, Rapid CSS or HTMLPad editors if the project spans multiple web languages.
Strengths
- Language-aware completion, syntax checks and code navigation cover HTML, CSS, JavaScript, PHP and several other web languages.
- The editor combines HTML/CSS validation, JavaScript checks and a PHP debugger with source editing.
- Project tools include search, reusable snippets, browser preview and FTP/SFTP/FTPS publishing.
- The product page describes a one-time license purchase rather than a recurring subscription.
Watch out for
- The current download page lists Windows 10 and 11 only.
- Personal, non-commercial and general-use licenses have different terms, so teams should choose the license matching their use.
Best for
- Web developers maintaining multi-language sites who want editing, validation and remote publishing in one desktop tool.
- PHP developers who want syntax checking and xDebug debugging alongside HTML, CSS and JavaScript editing.
- Small teams managing project files directly over FTP, SFTP or FTPS.
