1. Lucide — Best overall for modern apps

1,500+ clean outline icons, MIT licensed, actively maintained. A fork of Feather that never stalled. Every icon follows a strict 24px grid with 2px stroke — meaning your UI will look consistent without effort.

npm install lucide-react

import { Search, Settings, Bell } from 'lucide-react';

<Search size={20} strokeWidth={1.5} />

Use if: You need a general-purpose icon library for a React or Vue app and want active maintenance with a clean aesthetic.

2. Heroicons — Best for Tailwind CSS projects

292 hand-crafted icons from the Tailwind CSS team. Every icon comes in outline (1.5px stroke) and solid variants. Small set, but exceptionally polished — each icon is optimized for 24px and 20px.

npm install @heroicons/react

import { MagnifyingGlassIcon } from '@heroicons/react/24/outline';

Use if: You’re building a Tailwind CSS product and want icons that feel like they were designed alongside the framework — because they were.

3. Tabler Icons — Best for dashboards and large products

5,000+ icons make Tabler the largest consistent outline icon set available. Perfect for admin panels, dashboards, and products that need deep icon coverage without mixing styles.

npm install @tabler/icons-react

import { IconSearch, IconBell, IconSettings } from '@tabler/icons-react';

Use if: You’re building an admin panel, SaaS dashboard, or internal tool that needs hundreds of specific icons — Tabler almost certainly has what you need.

4. Phosphor Icons — Best for design systems needing flexibility

Every Phosphor icon ships in six weights: Thin, Light, Regular, Bold, Fill, and Duotone. This is the only major free library where you can change visual weight consistently across every icon — ideal for design tokens and multi-context systems.

npm install @phosphor-icons/react

import { Heart } from '@phosphor-icons/react';

<Heart weight="duotone" size={24} />

Use if: Your design system has multiple contexts (light/dark, prominent/subtle states) and you need consistent weight variation across all icons.

5. Material Symbols — Best for Material Design apps

Google’s 2021 replacement for Material Icons. 3,000+ icons with variable font technology — one file supports fill, weight, grade, and optical size via CSS. Apache 2.0 licensed.

<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Material+Symbols+Outlined">

.material-symbols-outlined {
  font-variation-settings: 'FILL' 1, 'wght' 400, 'GRAD' 0, 'opsz' 24;
}

Use if: You’re working in a Material Design ecosystem (Android, Flutter web, Google products) or need the widest icon coverage in a single library.

6. Bootstrap Icons — Best if you’re in the Bootstrap ecosystem

2,000+ icons designed on a 16px grid — unusually compact, making them crisp at small sizes like labels, badges, and table actions. No Bootstrap CSS required to use them.

npm install bootstrap-icons

Use if: You’re using Bootstrap in your project, or you need icons that look sharp at 14–16px.

7. Remix Icons — Best general-purpose alternative

2,800+ icons in line and fill variants. More opinionated than Tabler, more polished than many larger sets. Covers UI actions, media controls, finance, logos, and map icons.

Use if: You want a Lucide-scale library with more coverage and don’t mind a slightly warmer aesthetic.

8. Simple Icons — Best for brand logos

3,200+ brand and technology company SVG icons. Perfect for “tech stack” sections, “sign in with” buttons, and portfolio projects. CC0 public domain — freely usable everywhere. Each icon includes the official brand hex color.

Use if: You need brand logos for a portfolio, landing page, or “built with” section.
