our call
Start with CartBoss — highest vibe code, weakest moat.
CartBoss
CartBoss is essentially a webhook receiver paired with a delay queue, dynamic checkout link generator, and an SMS API integration like Twilio or Telnyx. Building the software logic takes a weekend, but you will need to handle telecom compliance and 10DLC registration manually.
