Six of eight AI app builders document a way to hand over an app, and they move six different things. Only Lovable and v0 have written down what happens when the person who built it is already gone. Compared September 2026.
Six AI app builders scored for real estate agencies in 2026 on the criteria that actually decide the build: CRM and MLS-feed fit, multi-agent client tenancy, custom domain per agency, code ownership, and the cost of running ten listing sites. No single tool wins every column. Webflow leads on design-led listing CMS and lowest entry cost, Bubble on complex client portals, Lovable on cheap multi-site hosting, Base44 on speed, and Totalum on owned, automatable Next.js portfolios. Pricing verified against each vendor's page in July 2026.
