1.7 free workflow, Pro, and Restore Purchases

SourceCanvas 1.7 is available now, free to download. Edit and preview SVG for free, try more diagram formats, and unlock professional exports and Mac automation with a one-time Lifetime Pro purchase.

Create, edit, and live-preview SVG for free. SVG, Mermaid, Graphviz, and PlantUML source files always remain openable, editable, and savable without a purchase.

Mermaid, Graphviz, and PlantUML each include one continuous 10-minute preview trial per device. Each timer starts only after that format's first successful render.

Unlock explicit SVG, PNG 1×/2×/3×, and vector PDF exports, nonblank templates, full non-SVG previews after each trial, and Mac MCP/Agent with native AI Preview. No subscription.

Customers who obtained the paid app before the free transition automatically keep Legacy Pro, with the same features as Lifetime Pro. No repeat purchase.

Buy directly on iPhone, iPad, Mac, or Apple Vision Pro, and restore on another device with the same Apple Account. If access verification fails, retry or restore; source files remain editable.

Choose Restore Purchases in SourceCanvas Pro or the purchase and access screen, using the same Apple Account as the original purchase. Direct purchase and restore work on iPhone, iPad, Mac, and Apple Vision Pro.

Documents and preview

Open .svg, .mmd, .mermaid, .dot, .gv, .puml, .plantuml, .iuml, or .pu. On Mac, drag these formats from Finder; .dot remains Graphviz source even when another app owns the extension. Automatic usually detects the renderer.

For render failures, check line/column diagnostics and try Fit Screen. PlantUML include/import directives and external images never load; SVG remote resources require explicit permission.

Export

SourceCanvas exports final SVG, vector PDF, and PNG 1x/2x/3x to a destination you choose. Blocked, failed, or timed-out SVG resources prevent an incomplete export.

Configure MCP Agent (macOS only)

Open Settings > MCP & Agent, enable Agent Service, run Connection Diagnostic, then choose Configure Installed Agents. ChatGPT/Codex, Claude Desktop, Cursor, Visual Studio Code, Gemini CLI, and Qwen Code are supported.

The first setup may show a system folder picker. Select the requested client configuration folder; later configuration is normally one click. Restart or reload the client, then check for seven SourceCanvas tools.
