Krom Automation Free vs Pro: Complete Feature Comparison
Krom Automation’s free plugin is a fully capable automation tool. You can build multi-step workflows, use merge tags, add conditions and delays, run the simulator, and access the full REST API, all for free, forever.
Krom Automation Pro extends the free plugin with triggers and actions for 24 third-party integrations, four exclusive workflow features, 101 additional templates, and a visual email builder. It’s a one-time purchase with no recurring fees.
This page gives you a complete, honest breakdown of both versions.
Quick decision guide #
Stay on the free version if your site runs on core WordPress and WooCommerce and you want to automate user lifecycle emails, post notifications, comment moderation, AI tagging, or HTTP requests to external services. The free version handles all of that well.
Upgrade to Krom Automation Pro if you need to connect to third-party plugins like Mailchimp, ConvertKit, LearnDash, MemberPress, Gravity Forms, or Slack. Also upgrade if you need recurring scheduled workflows, the visual email builder, or the ability to receive incoming webhooks from external services like Stripe or GitHub.

Frequently asked questions #
Do I need to install the free plugin before installing Pro?
Yes. Krom Automation Pro is an extension that requires the free plugin to be installed and active. Install free first, then install Pro alongside it.
Can I start with the free version and upgrade later?
Yes. Upgrading to Pro preserves all your existing workflows. Pro adds new triggers, actions, and features without changing or breaking anything you’ve already built.
What happens if my Pro license expires?
Existing workflows continue to run. You lose access to Pro-specific settings and can’t add new Pro triggers or actions, but automations already built and activated keep executing.
Is there a limit on how many workflows I can create?
No. Both free and Pro allow unlimited workflows with no execution caps.
Does Krom Automation work with multisite?
Pro is licensed per site. Contact wpRigel support for multisite licensing options.
