SF Schema Diagram by Near Partner

About

Salesforce Schema Builder is great for arranging objects and relationships on screen, but it gives you no way to export what you built. SF Schema Diagram fills that gap: it turns the canvas you already arranged into a portable entity-relationship diagram you can drop into your docs.


HOW IT WORKS

1. Open Setup → Schema Builder in your Salesforce org.
2. Drag the objects you want onto the canvas and arrange them.
3. Click the extension icon, then "Capture from canvas."
4. View the ERD in the popup, then copy it as Mermaid text or download it as a PNG.

The capture reads the diagram straight from the page you are already viewing — it follows the layout you arranged on the canvas, nudging objects apart where needed to keep the diagram readable.


WHAT YOU GET

- An interactive ERD rendered right in the popup.
- Copy as Mermaid — a standard erDiagram block you can paste into Confluence, Notion, GitHub, markdown, mermaid.live, or draw.io.
- Download as PNG — a ready-to-share image of the diagram.
- A "References only" toggle to hide non-reference fields when a diagram gets dense.
- Works on Enhanced Domain orgs (salesforce-setup.com Setup tabs), where the Salesforce REST API is not available. The capture is purely page-based, so it works everywhere Schema Builder runs.


PRIVACY — EVERYTHING STAYS ON YOUR MACHINE

- No outbound network calls. No analytics. No telemetry.
- No persistent storage of any kind — no chrome.storage, no cookies, no files on disk.
- Captured schema lives only in memory while the popup is open and is wiped the moment you close it.
- The extension only reads object, field, and relationship names — never any record data or values.
- It runs only on Salesforce domains, and only reads the page when you explicitly click "Capture from canvas."
