FAQ
Does PRO require the free plugin?
Yes. SpeedKit PRO is an add-on that extends the free SpeedKit plugin.
Will page caching conflict with my existing cache?
PRO auto-detects WP Super Cache, LiteSpeed Cache, W3TC, WP Rocket and more. If found, page caching is disabled with a notice.
Does Delay JS break my site?
jQuery and admin bar scripts are excluded by default. Add any other scripts to the exclude list if needed.
Is AVIF supported on my server?
Check the PRO settings page — it shows whether your server supports AVIF (requires GD 8.1+ or Imagick with AVIF).
Can I use it on multiple sites?
Each license is for one domain. Purchase additional licenses for more sites.
