What Are These Tools?
Every tool on Dev Codex is a free, browser-based utility designed for a specific developer pain point. They fall into three categories:
- Code Generators — Fill out a form and get production-ready code: WP_Query arguments, Magento layout XML, Sitecore config patches, Joomla extension manifests, and more. Output includes copy-to-clipboard and shareable URLs so you can bookmark or share pre-configured tool states.
- Query Builders — Visually construct complex queries for SharePoint CAML, CiviCRM API v4, Craft CMS element queries, and Salesforce SOQL. No more hand-writing XML or memorizing API syntax.
- Searchable References — Look up WordPress hooks, Drupal Twig template suggestions, Joomla plugin events, Graph API permissions, and CiviCRM entities. Each reference is filterable by category and includes code examples you can copy.
All tools run entirely in your browser — nothing is sent to a server. Your data stays local.
