Meron
What Meron is
Meron is a free, open-source email client with a unified inbox, kanban organization, threaded conversations, and customizable themes. It supports IMAP/SMTP email and RSS/Atom feeds, with Exchange available through DavMail. Automatic mailbox discovery, OAuth, and rich-text composition are included. Photos, designs, and documents from a thread are collected into a visual gallery and grid. Light, dark, and custom themes are available, and the project lists more than 20 languages. The privacy policy says emails, credentials, settings, personal data, and Google OAuth data remain on the user’s device rather than being uploaded or shared. The README describes encrypted local storage and operating-system keyring credentials. An optional local desktop MCP interface can give AI clients account access with per-client permissions. Meron runs on Android, iOS, Linux, macOS, and Windows under AGPL-3.0. The free plan costs nothing.
