Tippy.js

Checked 2026-10-31 on official sources. Official README verifies npm tippy.js, importing its constructor and dist/tippy.css, or CDN usage with Popper 2. Initialize against target elements with content/options; optional plugins and the official React wrapper are separately documented. MIT code with notices retained. GitHub repository is archived/read-only as checked today; no promise of ongoing upstream maintenance. Editorial: useful as a mature, detailed tooltip reference and for existing integrations, but new projects should weigh the archived status and a maintained positioning alternative such as the separately catalogued Floating UI. HTML content requires trusted/sanitized input, and rich menus need their own keyboard/focus semantics; calling a tooltip interactive does not guarantee complete accessible-menu behavior. No paid plan found. Website demo v6.3.7 is observed, not claimed to be a new release.
