More than 3,400 marks share one small format
Simple Icons solves a dull problem that grows with every integration a product adds. The catalog has more than 3,400 popular brand marks, each prepared as an SVG for a 24 by 24 viewbox. An icon object can carry its title, slug, hex color, source, path, SVG markup, and links to available licensing or brand guidance. Designers can download one file from SimpleIcons.org, while code can consume the same source through npm or Composer.
The 24 by 24 monochrome rule is the reason a grid of unrelated brands feels coherent. It is also a hard visual limit. Gradients become one color, wordmarks may give way to symbols, and a sponsor's official lockup may require spacing or colors that this set does not preserve. Simple Icons fits integration menus, social links, and technology badges. Brand campaigns and contractual sponsor pages should use assets supplied by each company.
Named npm imports keep thousands of paths out of the browser
Our sandbox pulled 593 packages for development, while named exports let an application ship only the icons it uses. The README shows an ES module import for one icon with a bundler that can tree shake. Each export contains usable SVG markup and path data, so React or plain JavaScript can render it without a second parser. TypeScript definitions are included. Catalog tools can import the whole namespace, though an ordinary application should inspect its production bundle.
Distribution is broader than npm. Composer installs the SVG directory for PHP, while jsDelivr and unpkg expose versioned package files. The dedicated CDN accepts a slug, color, optional dark-mode color, and an automatic viewbox query. The examples use major version 16. A floating @latest URL keeps updating, but the README says it returns 404 after an icon is removed. Exact versions or locally bundled assets give public pages a steadier dependency.
What happened when we ran it
Our sandbox installed Simple Icons in 34 seconds, pulling 593 npm packages and occupying 258 MB on disk. The build completed in 18 seconds. Mocha then ran 31,083 tests in 7 seconds, with 31,083 passing and 0 failing. npm audit found 0 known vulnerabilities across critical, high, moderate, and low severities. Our test method used commit 34c2250 in an unprivileged Node 22 Debian container with 3 CPUs and 8 GB of RAM.
We measured a checkout of 3,539 files, about 4,421 lines of source, and 6.1 MB before installation. We also counted 10 CI workflow files, a Dockerfile, and a tests directory. Nothing failed in the measured install, build, or test path. The 258 MB dependency footprint is still much larger than the source checkout, so package consumers should distinguish development cost from the handful of SVG paths that ought to reach a browser.
CC0 covers the repository, while brand permission stays with you
Simple Icons publishes the repository under CC0-1.0, yet its disclaimer says this does not make every included icon CC0. License data is an ongoing community effort and may be missing or outdated. The same warning applies to links for brand guidelines. A missing field does not mean a mark has no restrictions. Commercial teams should record the source and current rules for each selected brand, especially when recoloring a trademark or using it near an endorsement claim.
Brands can request updates or removals, and the maintainers say ordinary removals happen twice a year in major releases. That policy explains the 404 warning for @latest: catalog membership can change for legal or scope reasons. Pinning protects rendering from an unexpected deletion, but it does not freeze permission. The disclaimer asks users to check licenses and guidelines again because brand owners can revise them after an icon enters the package.
A one-year rule keeps the catalog selective
The contribution guide requires a brand to have existed for at least 1 year and to meet one of several verifiable popularity measures. It excludes personal brands and lists forbidden categories and companies. GitHub-only projects are judged through repository evidence when better signals are unavailable. This policy will frustrate teams whose product depends on a young or obscure service, even when they can supply a clean official SVG.
Accepted artwork also takes work. Contributors look for an official logo and primary color, fit the mark to a 24 by 24 canvas, optimize its path, add metadata, and run the checks. The latest release, v16.28.0 on August 2, added 3 icons and updated 2. GitHub showed 944 open issues and pull requests, with requests and submissions updated through August 26, while the repository's last push was August 25. That combination points to active curation rather than an abandoned queue.
The passing suite makes the package easy to trust technically
Simple Icons earns a place in a production interface when the job is consistent brand identification at small sizes. Our 31,083 passing tests remove much of the technical doubt, and the package offers direct files for teams that do not want its 593 development dependencies. The remaining work sits with the adopter: pin the asset version, ship only selected icons, and check the owner's rules for every mark that carries commercial weight.
Devicon is a better match for a technology-only catalog that needs colored variants. Font Awesome makes more sense when the same library must supply interface controls and brand symbols. SVG Logos preserves fuller artwork for cases where original color and wordmarks are part of the requirement. Simple Icons wins when uniformity, metadata, and breadth matter more than reproducing a complete identity system.
