About

SourceCanvas is a local editor for SVG, Mermaid, Graphviz DOT, and PlantUML diagrams on iPhone, iPad, Mac, and Apple Vision Pro. Start free • Create, edit, and preview SVG diagrams. • Open, edit, and save source files in all four formats. Your documents remain accessible without a purchase. • Try each non-SVG renderer once for 10 continuous minutes per device. Its timer starts after the first successful render. Lifetime Pro • Unlock explicit SVG, PNG 1×/2×/3×, and vector PDF exports. • Use nonblank templates and full Mermaid, Graphviz, and PlantUML previews after each trial. • On Mac, use the MCP Agent and native AI Preview with compatible local AI hosts. Lifetime Pro is a one-time in-app purchase, not a subscription. Customers who obtained the paid app before the free transition automatically keep equivalent Legacy Pro access. Purchase directly on iPhone, iPad, Mac, or Apple Vision Pro. Restore on another device with the same Apple Account. Rendering runs locally. No account or remote rendering service is required. External SVG resources are blocked unless you choose to allow them.

SourceCanvas 1.7 • SVG editing and live preview are free; every source file remains editable and savable. • One continuous 10-minute preview trial per device for each of Mermaid, Graphviz, and PlantUML. • A one-time Lifetime Pro purchase unlocks all explicit exports, nonblank templates, full non-SVG previews, and Mac MCP/Agent automation. • Existing paid customers automatically keep the same Pro features through Legacy Pro. • Redesigned purchase and access screens with Restore Purchases. • Build 22 test: On iPhone/iPad, edit the starter SVG in a new document. If StoreKit verification fails, use Retry or Restore Purchases; the source remains editable. Switch SVG, Mermaid, Graphviz and PlantUML, and confirm the format label follows the current source.
