What Iconstack is
Iconstack is a free SVG icon search and download service built around a catalog of more than 50,000 icons from multiple open icon libraries. It combines a browser interface for browsing and customizing icons with a public API and MCP server for developer workflows.
The site is positioned for both visual exploration and programmatic use: users can search by query, filter by library or style, change color and stroke width, and download or copy icons in common formats. The API page also shows direct support for Cursor, Claude Desktop, and Windsurf through the hosted MCP endpoint.
Core features
Multi-library coverage
Browse a large collection drawn from libraries such as Material Design, Tabler, Phosphor, Lucide, Remix, Bootstrap, Feather, and others listed on the homepage.
Basic customization controls
Adjust icon color and stroke width before export, which helps when matching an icon to an existing interface or design system.
Multiple output formats
Export or copy icons as SVG, PNG, or XML from the web interface, and fetch raw SVG or JSON responses from the API.
API and MCP access
Use the hosted API or MCP server from tools such as Cursor, Claude Desktop, and Windsurf to search and paste icons into code without a separate local setup.
Developer-friendly access
Work with a no-auth, CORS-enabled endpoint that the API page describes as free forever, with no API key required for the public search endpoint.
Common use cases
Browse and filter icon sets
Find an icon by name or concept, then narrow results by library, category, or style to get the exact asset you need.
Prepare icons for interface design
Adjust color or stroke width in the web UI before exporting so the icon better fits an app, website, or design system.
Embed icons in development workflows
Use the API or MCP server from an AI editor or coding client to locate an icon and insert its SVG directly into source code.
Programmatic icon retrieval
Fetch JSON search results or raw SVG from endpoints when you need icons in a script, build pipeline, or internal tool.
