| Editions | Contact Form 7 | Relevanssi Live Ajax Search |
| Pros | Completely free, with no upsells in the code; Several spam options: Akismet, reCAPTCHA, Turnstile, quiz, disallowed list; Stripe payment field and Brevo contact sync built in | Works with default WordPress search without configuration; Results can be restyled through theme template overrides; Uses Relevanssi automatically when it is active |
| Cons | No visual drag-and-drop builder; forms are markup; No conditional logic or multi-step forms without add-ons; Does not store submissions without Flamingo | Some themes need template or CSS changes to look right; Only the live results are improved; full search quality needs Relevanssi; Few settings, so layout changes need code |
