UI Frameworks & Libraries

About the ui frameworks & libraries category

The UI Frameworks & Libraries category covers every transparent PNG icon for the libraries that render the modern web. The major front-end frameworks (React, Vue, Angular, Svelte, Solid, Astro, Remix, Next.js), the headless and meta-framework layer, the CSS toolkits (Tailwind, Bootstrap, Bulma, Chakra), and the data-visualisation libraries that ship most analytics dashboards.

Use these icons in framework comparisons, component-library landing pages, CSS-toolkit roundups, and migration guides. When linking out to a framework's official documentation in long-form posts, the contextual outbound link signals to readers (and to search engines) that the content is genuinely sourced. The transparent PNG format also lets you stack the framework icon on top of branded gradients or product screenshots without any background mismatch.

Sizing tips: render these PNGs at 16, 24, 32, 48, 64, or 128 pixels for product UI; at 96–256 px for marketing surfaces; and at 320–512 px for hero illustrations. Because the source assets are vector at the CDN edge, the PNG you download will always be rendered at the requested size, not upscaled. For accessibility, always pair an icon with a short text label (the brand name itself works best) so assistive technology can announce the visual meaningfully. Avoid recolouring official brand marks for primary product surfaces — most brand guidelines disallow tinting — but a CSS filter for hover states is generally acceptable. Every icon in this set is licensed under CC0 1.0 Universal via the Simple Icons project, which means you can use them in commercial work without attribution, though linking back to IconDrop is appreciated.

How to work with these icons

Each ui frameworks & libraries brand mark on IconDrop is rendered on demand from the official Simple Icons SVG source as a transparent PNG at the resolution your browser asks for. That means the asset is always crisp at the rendered size — never upscaled, never blurry, never carrying the artefacts of a stale raster export. When citing a particular brand on a comparison page or in a roundup post, contextual outbound links to authoritative reviews or to the brand's own product page improve both editorial credibility and on-page SEO. Pair these icons with a short text label and you have a complete navigation row, feature tile, or comparison row.

If you are working on a dark-themed product, all of these PNGs sit happily on midnight, slate, or full-black backgrounds without any visible matte. For light themes, give the icon at least eight pixels of breathing room on every side so it doesn't crowd surrounding type. Pair the ui frameworks & libraries family with one or two complementary categories — for example a programming language mark next to a UI framework mark — to communicate an entire stack in a single visual band.

Licensing & usage

Every icon in this category is released under the Creative Commons Zero (CC0 1.0 Universal) dedication via the Simple Icons project. That means you can use them in commercial products, paid client work, internal tools, marketing pages, slide decks, and open-source projects without paying a cent and without an attribution requirement. The brand names and logos themselves remain the trademarks of their respective owners — CC0 covers your right to use these PNGs as visual elements, but does not transfer trademark rights or imply endorsement. For app-store listings, official press materials, or anywhere your usage might be construed as an endorsement, check the brand's own usage guidelines first. See the full license guide for sample edge cases.
