A free WordPress plugin with developer tools: SQL profiler, error log viewer, HTTP/Cron monitor, and database health check.
No. DevKit only runs for administrators and adds minimal overhead. Profiling is off by default.
Yes, but we recommend disabling Query Monitor to avoid duplicate hooks. DevKit will warn you about conflicts.
Only for the error log viewer. Other tools (SQL, HTTP, Cron, Transients, DB) work without WP_DEBUG.
All plugins have a free version.
