# toot [toot][toot] is a share page for Mastodon, allowing you to share stuff cross-instance. Just put in your post text and the instance URL and click "Toot!" And if you open this page with `text` URL parameter, it will be inserted in the text field. Same thing with `instance` URL parameter. This can be used to build custom share buttons for Mastodon: ```html Share on Mastodon ``` toot is used in [shareon][shareon], ethical social sharing buttons. ---- [](https://vercel.com) [toot]: https://toot.karamoff.dev [shareon]: https://shareon.js.org
