# 1LINK.IO

> 1LINK.IO helps app developers and marketers increase app installs with smart links. It provides device detection, customizable landing pages, and analytics to optimize app presence on the web.

1LINK.IO is a SaaS platform for smart app linking. Use a single link that automatically routes users to the correct app store based on their device, with built-in analytics and landing pages for desktop visitors.

1LINK.IO also provides an MCP server, so AI agents can create and manage smart links on your behalf. After signing up, generate an API key from the [Integrations page](https://app.1link.io/#/integrations) and connect it to any MCP-compatible client (Claude Code, Cursor, VS Code, etc.).
