AI icon libraries: what they are and who makes them
general-purpose open source sets, aggregators and icon font builders, brand logo collections, marketplaces with ai tools: Lucide, The Noun Project, Tabler Icons through Simple Icons.
Types of AI icon libraries
General-purpose open source sets
Lucide, Tabler, Bootstrap Icons, Phosphor, Feather, Heroicons and Iconoir give you interface symbols under MIT or ISC terms with no account. They differ in size, from Heroicons at 316 icons to Tabler at 6,287, and in style options such as filled variants. None of them names an AI feature.
Aggregators and icon font builders
Iconify loads icons from many sets through one API, with plugins for Tailwind CSS, UnoCSS and Astro. IcoMoon assembles custom icon fonts and SVG packs in a browser app, with free and paid plans. Both focus on assembling and shipping icons rather than on one drawn style.
Brand logo collections
Simple Icons holds over 3,400 brand marks as SVG under CC0 1.0, which suits footers, integration pages and login buttons. It contains no general interface symbols, and the marks remain the property of their owners, so trademark rules still govern how you display them.
Marketplaces with AI tools
The Noun Project is a marketplace of nearly 10 million icons and photos, with a free account, paid Noun Pro plans, an icon API, and Noun Studio for editing and generating derivative icons. It is the only entry here with a credit-based AI service, sold on paid plans.
