Visualforce Explained
Visualforce pages use an MVC-style architecture where markup (the view) is paired with an Apex controller (the logic layer) and Salesforce objects (the model). Each page is accessible via a unique URL and can be embedded in page layouts, served as standalone tabs, or surfaced in Salesforce Mobile. Standard components handle common UI patterns like data tables, input forms, and detail displays, while custom components enable reusable blocks across pages.
Although Lightning Web Components have largely superseded Visualforce for new projects, thousands of production orgs still rely on Visualforce for PDF generation, complex email templates, and legacy features that predate Lightning Experience. Migrating these pages requires careful audit of controller dependencies and JavaScript remoting calls. Clientell AI can inventory your org's Visualforce usage and recommend a phased migration path.
