Metis Suite is an open-source (AGPL) mail, calendar and drive client that runs on your own server, or on Metis Cloud if you'd rather we host it.

Connect the accounts you already have (Gmail, Outlook, Zoho, IMAP, CalDAV, Google Drive, OneDrive, S3, WebDAV, SFTP) and use them in one app:

📬 One merged inbox, with calendars and drives alongside

🤖 An AI assistant across mail, calendar and files, using your own model (OpenAI, Anthropic, or any OpenAI-compatible endpoint, including local ones). It asks before it sends or deletes anything

🔒 Trackers and remote images blocked by default, credentials encrypted, 2FA for everyone

⚙️ Workflows to automate your inbox, and an MCP server for Claude, Cursor and VS Code

💻 Web, desktop and Android apps
