Dev Limits – Server Limits Manager

Dev Limits – Server Limits Manager

Description

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.

Installation

  1. Upload the dev-limits-server-limits-manager folder to /wp-content/plugins/, or install through Plugins Add New.
  2. Activate the plugin through the Plugins screen.
  3. Open Dev Limits in the admin menu.
  4. On the Dashboard, review your health score and recommendations.
  5. Open Profiles and choose a workload that matches your site (Blog, WooCommerce, Elementor, and others).
  6. Use Snippets to copy configuration code for your server stack, or open Configure to apply supported changes with backups.

No configuration is required for read-only analysis. Dev Limits works immediately after activation and does not modify server files by itself.

Using Configure (write) mode

  1. Open Dev Limits Configure.
  2. Enable Configure mode when you are ready to apply changes.
  3. Review the recommended values for your active profile.
  4. Apply changes to supported files (wp-config.php, .htaccess, or .user.ini where compatible).
  5. Dev Limits creates a backup before each write, validates syntax, and can roll back on failure.

Hosts can disable write mode by defining DEV_LIMITS_ALLOW_WRITE as false.

FAQ

Does Dev Limits automatically increase my upload size or memory limit?

No. Dev Limits is read-only by design. It shows you the exact snippet to increase a limit, but you apply it yourself — unless you explicitly enable Configure (write) mode.

How do I increase my maximum file upload size?

Open Snippets, choose your workload profile, and copy the snippet for your server stack (.user.ini, .htaccess, nginx.conf, etc.). The Dashboard confirms the new value once your host applies it.

Why didn’t my limit change after I added the snippet?

Some hosts cap limits at the server level, ignore .htaccess php_value lines (common on FastCGI / PHP-FPM), or require a restart. Use Hosting Detection to see which methods work on your stack. Export a diagnostics report and share it with your host if needed.

Is Dev Limits compatible with multisite?

Yes. Each site stores its own profile and settings. The uninstall routine cleans up every site on the network.

Does Dev Limits collect any data or make external requests?

No. Dev Limits collects nothing, sends nothing, and makes no external requests. All analysis happens locally on your site.

Is it compatible with WooCommerce and Elementor?

Yes. Dedicated workload profiles and Site Health checks help confirm your server is ready for WooCommerce stores and Elementor page builders.

Can developers extend it?

Yes. Dev Limits ships a service container plus documented actions and filters so add-ons can register new metrics, profiles, snippet formats, and admin pages.

Can Dev Limits change my limits for me?

Only if you explicitly opt in. Configure (write) mode can apply selected limits to wp-config.php, .htaccess, or .user.ini. It always creates a backup first, validates before saving, rolls back on failure, and logs every action. Hosts can disable write mode by defining DEV_LIMITS_ALLOW_WRITE as false.
