Nucleo review
A broad, paid icon library with strong customization and developer exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Nucleo combines a curated icon library with web, Mac, and Windows apps for designers, developers, and product teams. Its families include Core, UI, Sharp, Pixel, and Micro Bold, covering distinct visual treatments and sizes. The library supports commercial use, while the app helps users browse, search, favorite, and organize icons into projects. Customization includes size, padding, colors, rotation, and stroke values, making Nucleo suitable for teams that want consistent icon assets without creating a collection from scratch.
Pricing is structured around one-time purchases rather than a recurring subscription. Micro Bold Icons costs $69 and includes 1,827 SVG icons. Core Icons and UI Icons each cost $99, with 19,128 and 16,520 icons respectively. Sharp Icons costs $99 for 3,478 icons, while Pixel Icons costs $99 for 3,329 icons. The All Icons Bundle costs $405 and includes 44,282 icons across the UI, Core, Sharp, Pixel, and Micro Bold families. A Team License adds shared icon projects, role management, and Mac/Windows app access. This structure suits buyers who prefer outright ownership and can select a family or commit to the complete collection.
For implementation, Nucleo offers single SVG files, SVG sprites, SVG symbols, PNG, icon fonts, and Vue or React components. It can import SVG, SVG fonts, SVG symbols, IconJar, and JSON files, and it includes AI coding integration. These formats give product teams options for design systems, web interfaces, and application projects, while React and Vue support helps align exports with common frontend workflows. Nucleo is a strong fit for teams seeking many coordinated families, desktop management, and flexible exports. Teams wanting a free starting point or a narrowly focused icon set may prefer a simpler, lower-commitment option.
