Start with Evidence — highest vibe code, weakest moat.
Evidence
Evidence is a standard social proof notification tool. Its primary function is listening to order webhooks, saving event logs, and outputting them via a small frontend script tag. An AI agent can build a fully functional clone using edge functions and Redis/PostgreSQL in a weekend.

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.
