icons0

icons0 is an icon search engine over more than 200,000 icons from 150+ open-source collections, from Ant Design and Carbon to Boxicons and Catppuccin, showing how long each search took. Alongside the web interface it runs an MCP server, so a coding agent can look up and insert icons directly. Developers who hop between icon sets get one search for themselves and their agents, and the live index listed 236 collections when captured.
