Definition
Visualforce is Salesforce's legacy markup language for building custom user interfaces. It uses a tag-based syntax similar to HTML and can be paired with Apex controllers to create pages with custom layouts, logic, and data access. While still supported, Salesforce recommends Lightning Web Components for new development.
Real-World Example
A developer at Heritage Insurance maintains a Visualforce page that generates a printable PDF quote for clients. The page uses a custom Apex controller to pull Opportunity and Product data, formats it into a professional layout with the company logo, and renders it as a downloadable PDF when the sales rep clicks "Generate Quote."
Why Visualforce Matters
Visualforce is Salesforce's legacy markup language for building custom user interfaces that go beyond what standard page layouts can provide. Using a tag-based syntax similar to HTML, developers create pages with custom layouts, dynamic data binding, conditional rendering, and interactive components. Visualforce pages are powered by Apex controllers that handle server-side logic, database queries, and business rule enforcement. While Salesforce now recommends Lightning Web Components for new development, Visualforce remains widely used for specific use cases like PDF generation, email templates with complex formatting, and embedded pages within Lightning Experience.
Organizations with long-standing Salesforce implementations often maintain dozens or even hundreds of Visualforce pages that power critical business processes. The challenge is that Visualforce's server-side rendering model results in slower page interactions compared to Lightning's client-side approach, and view state management adds complexity as pages grow. However, migrating away from Visualforce requires careful planning because many pages contain deeply embedded business logic in their controllers. Teams must balance the cost of maintaining legacy Visualforce pages against the investment of migrating to LWC, typically prioritizing high-traffic, user-facing pages for migration while leaving low-traffic utility pages like PDF generators on Visualforce where they continue to work well.
How Organizations Use Visualforce
- Heritage Insurance — Heritage maintains a Visualforce page that generates printable PDF quotes for clients. The page uses a custom Apex controller to pull Opportunity and Product data, formats it into a professional layout with the company logo, and renders it as a downloadable PDF when sales reps click the Generate Quote button. This PDF generation use case is one where Visualforce excels over Lightning components.
- Meridian Legal Group — Meridian built a complex multi-section intake form using Visualforce that collects client information across six categories with conditional field visibility and real-time validation. The form auto-saves progress and generates a case record when submitted. While they plan to migrate to LWC eventually, the Visualforce version has processed over 50,000 intakes reliably.
- Atlas Manufacturing — Atlas uses a Visualforce email template to send branded order confirmation emails that include dynamic product tables, pricing breakdowns, and shipping details pulled from the Order and Order Item objects. Standard email templates could not achieve the complex tabular formatting required by their brand guidelines.
