Cons
Deployment is tied to the Internet Computer blockchain, an unfamiliar and less battle-tested foundation than conventional cloud hosting for most business buyers
Credit allowances on lower tiers (10-20/month) are modest for anyone building more than a small project
Category association with crypto/blockchain may deter buyers who want a conventional no-code app builder without the blockchain layer
