Free where it should be free.
The free version genuinely solves the problem — it is the whole async engine, not a teaser. Pro is for the sites where background work is operationally serious: stores, agencies, networks.
Core — $0

- Overview dashboard and queue status
- Site Health checks, including missing-crontab detection
- Production setup with copy-paste crontab commands

No email, no signup — just the plugin. Install guide here. Also under review for the WordPress.org directory.
Pro
- Priority lanes: Express / Standard / Housekeeping
- Database-contention shield & adaptive throttling
- Checkout Priority Mode for WooCommerce
- Alerts: email, Slack, Discord, PagerDuty, webhooks
- Multisite network dashboard, REST API, weekly digest
The licence covers updates and support. If it lapses, the plugin keeps working. No features are held hostage to a renewal.
Three prices, and what separates them is site count.
Every paid tier has the same features. You are not paying more for capability, only for how many sites the licence covers — so a one-site business is never sold a cut-down product.
| Licence | Sites | Price |
|---|---|---|
| Core | unlimited | free, forever |
| Pro Solo | 1 | $49 / year |
| Agency | up to 25 | $199 / year |
| Unlimited | no limit | $499 / year |
Card and PayPal both accepted. Checkout, receipts and EU VAT invoices are handled by Freemius as merchant of record.
A licence covers a year of updates and support. When it lapses the plugin keeps working — you simply stop receiving updates. The free core is GPL and free forever, licence or not.
