AppSumo & SaaS Lifetime Deal

This week's SaaS lifetime deals: one solid buy, a graveyard of skips

Mid-grade week across five deal platforms. Blip AI ($59, AppSumo) earns a buy now with 78% verified savings. Katteb gets a conditional buy pending page verification. Presenti AI is a wait. Every StackSocial candidate fails vendor health. Ecosystem alerts: ByDesign.io security flaw, Sendapp removed from AppSumo, bait-and-switch patterns in Replient, Zernio, and Straico.
