About Benzo Build

Why we exist

Design software should not cost $15 a month forever. A student in Karachi, a shop owner in Lagos, a teacher in rural India — they all need to make posters, flyers, and social posts. They can't all afford Canva Pro.

Benzo Build is our answer. Everything works offline. Nothing is behind a paywall. No accounts, no watermarks, no feature gates. And because it's open source, it stays that way.

What's inside

• Full design editor — text, shapes, images, icons, emojis, multi-page
• Smart snapping, alignment guides, layers, undo/redo
• Image filters — brightness, contrast, saturation, blur, rounded corners
• Gradients — linear and radial on every shape
• Text effects — shadows, strokes, case transforms
• 14 animation presets with live preview
• Stock photos from Pexels — search and insert instantly
• Export to PNG or JPG at 1×, 2×, or 3× scale
• Save and load projects as JSON files
• 18 templates — YouTube, Instagram, Pinterest, business, print
• Runs entirely in your browser — no server needed

Tech stack

Pure HTML, CSS, and JavaScript. No frameworks, no build step, no dependencies. core.js manages state and history. elements.js handles creation and interaction. io.js handles images and export. stock.js talks to Pexels.
