Hammity is a free instant messaging and voice platform made in the United Kingdom for friends, groups, and communities. Built with privacy, security, and community support at its core, it is available as a downloadable app for Linux or can be used in a web browser, with an option to try it without an email. During the public beta, registrations are limited.

The platform combines private direct messages and group chats with community channels, file sharing, link previews, and Markdown formatting. Users can join voice and video calls from multiple devices, share screens, and use controls for muting, camera access, noise suppression, and echo cancellation. Community management features include roles, permissions, moderation tools, audit logs, webhooks, and bot support. Search, message-history filters, and keyboard shortcuts help people navigate conversations, while custom emojis, stickers, saved media, CSS themes, and display settings allow personalization.

Hammity also provides help documentation, a blog, a roadmap, and a community space for updates and discussion.
