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

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.
