our call
Start with Swym — highest vibe code, weakest moat.
MailMunch
MailMunch is essentially a collection of overlay triggers (exit-intent, timers) connected to a basic contact store and email dispatcher. Paying monthly for modal triggers when modern UI components and transactional email APIs exist is unnecessary. Rebuilding the popup logic takes hours; mailing lists can be sent to Listmonk or directly to Resend/Klaviyo.
