Feature Comparison Summary
FlowMattic turns WordPress into a self-hosted automation hub with unlimited workflows, 861+ integrations, and an AI builder that runs on your own API key. The trade-off is that you're the sysadmin: performance depends on your hosting, and non-WordPress sites are out of luck. Overall, it's a strong pick for WordPress users tired of per-task billing.
Splunk unifies petabytes of machine data for security, IT, and AI agent monitoring, with strong customer results like Specsavers' 10x faster MTTR. But its core products hide pricing behind custom quotes, and teams need skilled staff to run it well. Overall, it's a proven enterprise pick if you can absorb the cost and complexity.
