About this plugin
Dev Limits helps you view PHP and WordPress server limits in one admin dashboard, score them against a workload profile, detect your hosting stack, and apply changes safely — or copy the exact snippet for your server.
The plugin is read-only by default. Nothing on your server changes until you opt in to Configure (write) mode, which adds automatic backups, validation, verification, and rollback when you apply changes from the admin.
Key features
- Read-only by default. Nothing changes on your server until you opt in to Configure mode.
- Health score engine. A 0–100 score with recommendations tuned to your workload profile.
- Hosting detection. Identifies Cloudways, Kinsta, WP Engine, SiteGround, Hostinger, cPanel, Plesk, Apache, Nginx, LiteSpeed, OpenLiteSpeed, and CloudLinux — and shows which configuration methods work on your stack.
- Eight workload profiles. Blog, Agency, WooCommerce, Elementor, Membership, LMS, Large Media, and Custom — with profile comparison and one-click activation.
- Analyzer. PHP modules, ini_get(), WP constants, server variables, environment detection, and warnings.
- Snippets for every stack. Auto-generated wp-config.php,.htaccess,.user.ini, php.ini, nginx.conf, and Apache snippets — only compatible formats are highlighted.
- Configure with safety. Read/write modes, automatic backups, verification engine, rollback, and safe apply.
- Debug Center. Manage WP_DEBUG, WP_DEBUG_LOG, SCRIPT_DEBUG, SAVEQUERIES, and WP_DEBUG_DISPLAY with safe presets.
- Diagnostics export. Full TXT and JSON reports with system information, warnings, and recommendations.
- Site Health integration. Adds limit checks and a debug-information section to Tools → Site Health.
- Local analysis only. No telemetry. GPL compatible. Multisite ready. Translation ready.

Dev Limits does not collect, store, or transmit personal data, and it does not make external or remote requests. All limit analysis and report generation happens on your server. The diagnostics report is created only when you generate it.
