Hermes is a free, open-source Facebook Messenger client written in Swift and AppKit. No Electron, no web page in a window: it looks and feels like Apple's Messages.
Replies, tapbacks, polls, themes and calls, drawn with Apple's own controls. Every screenshot here is the real app, running on made-up chats.
Double-click a message to react, just like in Messages. Replies show their quote with a line to the message they answer.
Group polls look like they do in Messages: a bubble per choice that grows with its votes and shows who voted. Click to vote, or add a choice.
Calls ring with a banner in the corner of your screen, like a system notification. Missed and finished calls show up in the chat as cards with Call Back.
Double-click any chat to open it in a window of its own, with its picture, name and buttons in the title bar. The toolbars are customizable, in the main window and in chat windows.
Add another Messenger account with File › Add Account…, and switch between them from the Account menu. Hermes opens with the one you used last.
Hermes plugs into the system the way Apple's own apps do.
With the sender's picture, Reply right from the banner, and Mark as Read.
Send messages and files, edit or unsend the last one, mark chats read or unread.
Your messages show up in Spotlight; pick one to jump right to it.
Share pictures, files and links to a chat from any app.
Your recent chats on the desktop. Click one to open it.
Unread count on the icon; your recent chats in its menu.
Contact cards from your Contacts, and their nicknames if you prefer.
New versions come from the GitHub releases, notarized by Apple.
Follows your Mac's appearance, with Liquid Glass throughout.
Hermes is for talking to people. These won't be added, ever.
Hermes is free and will always remain completely free.
No paid version, no subscriptions, no in-app purchases.
A Swift app on top of a Go core, built on the open-source libraries behind the mautrix Messenger bridge.
Swift and AppKit, with the same controls, sheets, menus and Liquid Glass as Apple's own apps.
A Go core speaks Messenger's web protocol through mautrix-meta, and handles encrypted chats with whatsmeow.
Messages, keys and your session are stored locally and go only to Meta's servers. No analytics, no other servers.
Open the DMG and drag Hermes to Applications.
