Company data in shadow AI apps built on Lovable, Bolt, and Replit lives in a database the platform provisions for each app, on vendor-managed infrastructure outside your Microsoft tenant. Lovable and Bolt build their backends on Supabase, Replit runs its own PostgreSQL service, and all three can add a user login that runs outside Microsoft Entra ID by default.
Let's say a sales manager describes a commission tracker to a vibe coding tool and shares the link with the team. Once the team starts using it, deal values and customer names sit in a hosted database behind a login page nobody in IT has seen. A Gartner survey of 302 cybersecurity leaders found that 69% of organizations suspect or have evidence of employees using prohibited public GenAI. Gartner also predicts that more than 40% of enterprises will have a security or compliance incident linked to shadow AI by 2030.
Lovable's built-in backend bundles a database, file storage, authentication, and serverless functions on Supabase's open-source foundation. According to Lovable's Cloud documentation, the backend is enabled by default for every workspace. When a prompt asks for a login or file uploads, Lovable either turns Cloud on automatically or asks the builder in chat.
Bolt launched Bolt Cloud in August 2025, and every new project now includes hosting and user authentication without a separate account. Bolt Cloud runs on Netlify and Supabase, publishes projects to a free bolt.host subdomain, and creates a database automatically when a project needs one.
Replit's database documentation states that every Replit App comes with a database by default, including 20 GB of free storage. Since December 4, 2025, new development databases run on Replit's own infrastructure in place of Neon. Replit Auth lets people sign in with their Replit accounts, and the Replit Agent adds it whenever a prompt asks for it.

CloudServus is a top 1% Microsoft Solutions Partner globally and an Azure Expert MSP. Microsoft awards these designations for demonstrated technical competency, customer success metrics, and investment in certified engineers. The CloudServus shadow AI governance practice maps every AI tool in use and the data each one reaches. It then applies Purview classification and Entra ID access controls to the apps the business decides to keep. An AI Readiness Assessment measures infrastructure, data quality, and risk management before the next prompt-built app goes live.
A shadow AI app is software an employee builds with an AI coding tool such as Lovable, Bolt, or Replit and runs without IT approval, security review, or monitoring.
Lovable Cloud stores app data outside your Microsoft 365 tenant, on Lovable-managed infrastructure in the Americas, Europe, or Asia Pacific, and the region cannot change once Cloud is enabled for a project.
Purview DLP and retention policies apply to Microsoft 365 workloads and connected sources. A database hosted by Lovable, Bolt, or Replit stays outside those policies until IT brings the app under governance.
