Most Salesforce projects start with a grey-box wireframe or a slide, and the review meeting ends up being about the mock-up instead of the requirement. SFProto draws the page the client will actually get.
Describe the page, or paste the Jira story with its acceptance criteria. When the request could go several ways, SFProto asks first: what the button is called, which options the popup offers, what happens after each one. Then it builds an Opportunity, Case, Account or any other Lightning record page in the real Lightning Design System: highlights panel, Sales Path, Details, Activity, Chatter and related lists, in both the classic and the current Salesforce look.
The page behaves like Salesforce. Interact mode runs quick actions, screen flows with choice cards, record search and file attachments, activities and Chatter polls; lookups open their compact-layout hover cards; related lists show as tables or tiles. Multi-step prototypes and Experience Cloud portals are built the same way, and process flows can be drawn beside the pages they lead to.
When the page is agreed, Export writes the user story, a data dictionary and Gherkin acceptance criteria for Jira, plus Lightning page metadata and LWC scaffolding for the developers. Share links open in a browser with a banner saying it is a prototype, and embed in Confluence, Jira or Notion.
There is no org, sandbox or licence involved: nothing connects to Salesforce. Free to start; Starter is $25 a month for 150 AI credits, exports and share links without the watermark.
