DevPulse

DevPulse is a self-hosted error tracking and performance monitoring plugin for WordPress, similar to Sentry but free and running on your own server.

Features:

• Captures PHP errors, warnings, notices, and fatal errors
• Captures unhandled exceptions automatically
• Frontend Core Web Vitals (LCP, INP, CLS, TTFB, page load) — real-user Lighthouse metrics
• Lightweight — the backend handler has zero JS footprint; the vitals bundle is ~4 KB deferred
• Configurable via the WordPress admin or wp-config.php constants
• Works with any self-hosted DevPulse server

Privacy: All error data is sent to your own server. Nothing leaves your infrastructure.

Configuration

You can configure the plugin via Settings → DevPulse in the WordPress admin, or by defining constants in wp-config.php:

define( 'DEVPULSE_DSN',     'http://your-server:8000/api/ingest/YOUR_API_KEY' );
define( 'DEVPULSE_ENV',     'production' );
define( 'DEVPULSE_ENABLED', true );

Constants take precedence over admin settings.

Running the DevPulse server:

docker compose up -d

See the DevPulse GitHub repository for full server setup instructions.
