Tessera Designer is a Mac application that turns shapes, images, text, and symbols into repeatable tiles and filled canvases you can use anywhere—UI, print, branding, or motion. It enables users to create seamless pattern assets quickly for various design applications.

The app features two main modes: Tile Mode generates a single tile that repeats flawlessly in both directions with seam-free edges for textures, backgrounds, and UI fills, plus live preview while adjusting settings. Canvas Mode fills an exact-size canvas in one pass, allows pinning fixed elements precisely, and auto-balances remaining space for cohesive layouts.

Users can choose from a large number of symbols like shapes, lines, texts, emojis or symbols—or add their own images. The app provides extensive customization options including opacity, rotation, size, font, style and more, with seed-based generation for perfectly repeatable results. Recent updates added collision shape tools, multi-line text support, font family and weight options, and improved controls.

The app exports PNG at exact pixel sizes and PDF for crisp, vector-friendly output. It offers benefits including fast generation of clean, export-ready patterns that look great for various applications.

Tessera Designer is designed for designers and developers who want patterns that look great, generate fast, and export clean. It requires macOS 26.1 or later and supports Family Sharing for up to six family members.
