This is an overview compiled from the official website, documentation and GitHub README. We have not tested it ourselves. Features and pricing are subject to the official pages; sources are listed at the end.

What it is

Lucide is an open-source icon collection that supplies vector graphics for digital user interfaces as well as physical or printed materials. Originally created as an open-source fork of Feather Icons, the project has evolved into an independent, community-driven icon toolkit. In software development, a “fork” refers to an effort where contributors take an existing open-source codebase and actively maintain or expand it under a new direction.

At its core, the library delivers icons in the Scalable Vector Graphics (SVG) format. Unlike raster image formats that rely on a static grid of individual colored pixels, vector graphics define shapes through geometric formulas and coordinates. This fundamental design characteristic ensures that icons remain sharp, clean, and crisp regardless of display resolution, zoom level, or physical screen size.

According to the project README, the repository provides more than 1,600 vector files for displaying symbols and icons. Meanwhile, the official project website indicates that the collection has grown to include 1,891 searchable icons as of version v1.57.0. The toolkit was created by software engineer Eric Fennis, and it is actively maintained alongside core maintainers Karsa Rigó and Jakob Guddas, along with community contributors. The project’s development and infrastructure receive support from corporate sponsors, including Vercel and DigitalOcean, alongside community and financial backers such as Zephyr Cloud, pdfme, Pax Historia, Fina Money, and Open Collective donors.

What it can do

Lucide serves as a versatile iconography resource built to simplify the inclusion of consistent symbols across digital products. The project emphasizes strict design guidelines so that every symbol maintains a coherent visual balance, uniform aesthetic weight, and clear legibility when placed alongside other icons in an application.

A key capability of the library is visual adaptability. The assets can be styled to match the specific needs of an interface. Users can adjust fundamental properties such as icon color, overall display size (with a standard default size of 24 pixels featured in the documentation), stroke width (such as 2 pixels), and non-scaling stroke behavior. Adjusting stroke width allows teams to control the thickness of an icon’s outlines, while non-scaling stroke properties ensure lines maintain their relative weight regardless of how the icon is scaled.

To make integration straightforward for modern software engineering teams, Lucide provides dedicated packages across various programming ecosystems. Rather than forcing developers to manually copy and paste raw SVG markup into their applications, official packages are available through major package registries. These official distributions include:

lucide: the base JavaScript package for standard web environments.
lucide-react: specialized components for React applications.
@lucide/vue: component bindings for Vue projects.
@lucide/svelte: icon elements tailored for Svelte.
lucide-solid: component wrappers for Solid applications.
lucide-preact: components built for Preact environments.
lucide-react-native: dedicated support for React Native mobile development.
@lucide/angular: bindings designed for Angular projects.
@lucide/astro: integration support for the Astro framework.
lucide-static: a distribution providing static SVG assets.

According to the official project website, these packages support “tree shaking.” In modern web development, tree shaking is an optimization process performed by build tools that inspects application code to identify which modules are actually being used. Because Lucide supports tree shaking, an application only bundles the exact icons that are explicitly imported in the project files, discarding all unused icons to prevent unnecessary bundle size bloat.

Beyond coding environments, Lucide supports design workflows through an official Figma plugin accessible directly from the Figma Community directory. This plugin allows product designers to search the icon library and place vector shapes directly onto design canvases.

Importantly, Lucide maintains an explicit policy regarding company trademarks: the library does not accept brand logos and does not intend to introduce them in the future. According to the project maintainers, this deliberate boundary is maintained due to legal restrictions surrounding trademark usage, the desire to preserve strict visual design consistency, and the practical challenges of maintaining rapidly changing corporate brand marks. For developers who integrate with language models or automated tooling, the project also offers organized documentation feeds accessible via designated web text files.

How to get started

Getting started with Lucide involves choosing the workflow that best fits your design or development setup.

For software developers, the initial step begins by exploring the documentation guide and icon index on the official website. Teams can search through the catalog of available symbols to verify that the required metaphors exist for their product interface. From there, developers identify the appropriate package for their technology stack, whether that involves React, Vue, Svelte, Angular, Astro, Solid, Preact, React Native, or generic JavaScript. Because official packages are distributed across standard package managers, developers can add the corresponding package name directly into their project configuration.

Once the package is declared, icons can be brought into individual view files using modular imports. Because the library is tree shakable, projects can import specific icon names as isolated components or functions. Developers can then apply visual customizations directly within their markup or stylesheets, setting parameters for dimensions, outline color, and stroke thickness to harmonize the symbols with the surrounding typography and user interface elements. Projects requiring standalone graphic files rather than framework components can leverage the static SVG package or download raw vector files directly.

Designers can begin by visiting the Figma Community page to install the official Lucide Icons plugin. Once enabled inside Figma, designers can open the plugin interface, search for relevant icons by keyword, and drop editable vector paths directly into layout frames and design systems.

For questions, troubleshooting, and collaboration, the Lucide project maintains an active Discord server where users and maintainers interact. In addition, contributors who encounter errors in the documentation or wish to propose new icons can consult the official contribution guidelines hosted on the GitHub repository to participate in the project’s ongoing development.

Pricing and requirements

Pricing and plans for Lucide are subject to the official page at https://lucide.dev/. From a licensing perspective, the project documentation states that Lucide is released under the permissive ISC License. This open-source license allows the toolkit to be used completely free of charge for both personal and commercial projects without licensing fees.

Regarding technical requirements, Lucide is designed to function within any software or creative environment capable of working with modern web standards or vector imagery:

Web and mobile environments require an environment compatible with modern package managers and ECMAScript modules, or support for frameworks such as React, Vue, Angular, Svelte, Solid, Preact, Astro, or React Native.
Design workflows require access to Figma to run the official community plugin.
Static workflows require only a platform, operating system, or application capable of displaying or embedding standard SVG files.

Who it is for

Lucide is suited for a broad range of technology practitioners, creative professionals, and organizations looking for a unified visual icon language:

Frontend developers building modern web and mobile applications who value lightweight assets, modular component architectures, and tree-shaking capabilities to keep application bundles minimal.
UI and UX designers who use Figma to construct wireframes, design systems, and high-fidelity interface prototypes and want design assets that align directly with production code.
Full-stack engineers and independent creators who need a versatile, ready-to-use symbol collection for side projects, internal dashboards, and client applications without dealing with restrictive commercial licensing costs.
Open-source community members interested in contributing to community-governed software through icon design, documentation improvements, or code enhancements.
