Download
Version 0.2.0-alpha — all files on the Releases page
| System | Package |
|---|
| Windows 10/11 (x64) | .zip — extract and run Vectopen.exe |
| macOS (Intel + Apple Silicon) | universal .dmg / .zip — not yet tested on a real Mac |
| Linux (x86_64) | .deb, .rpm, portable .tar.gz |
Alpha builds are not signed yet: see the installation guide for the Windows and macOS warnings.
Features
- ✏️ Drawing & node editing — pen, Bézier and brush (with tablet pressure), full node editing; rectangles, ellipses, polygons, stars and a shape library (heart, drop, arrows, cloud…).
- 🖼️ Vectorize images with AI — turn logos, icons, scans and drawings into vector shapes (VTracer: Bézier, polygon or pixel output). Two offline AI tools prepare the image: background removal (U²-Net) and ×4 upscaling (Real-ESRGAN). The models ship inside the app — nothing is uploaded. (Linux build in 0.2.0-alpha.) Guide →
- 🎨 Colour & gradients — solid, linear and radial gradients on fill and stroke, edited on the canvas.
- ✨ Effects, filters & shaders — shadows, glow, bevel, 3D, overlays; image filters (frosted glass, grain, duotone, neon, glitch, halftone…); a live shader editor with templates.
- 🗂️ Professional layers — sub-layers, clipping masks, type icons, thumbnails, compact view, search filters.
- 📄 Many artboards, huge files — the
.vtc format loads pages on demand: 1,000 pages / 100,000 objects open in ~1.4 s.
- 🔤 Text & typography — point and paragraph text, linked frames, Google Fonts, per-letter effects, text to curves.
- 🧩 Scripts & add-ons — a GDScript console with the Vectopen API; install add-ons from
.zip, folder or .gd.
- 🤖 MCP server — let an AI agent drive a running Vectopen through the same undoable operations as the UI.
- 🖥️ Three interfaces — Smart, Modern and Pro; light/dark theme; 10 languages.
- 📤 Export — SVG, PDF, EPS, PNG, JPEG, WEBP, Godot scenes. Import — SVG (real Bézier curves), PNG/JPEG/WEBP, glTF.
Run from source
Requires Godot Engine 4.7+ (standard build, no .NET).
git clone https://github.com/malabo1990/-Vectopen.git
cd -Vectopen
godot --path . --editor
The main scene is res://scenes/canvas/canvas.tscn. The native parts (text shaping and the vectorizer) are Rust GDExtensions in rust/; packaged builds are produced with tools/package_release.sh.
