UnInbox is an open-source collaborative email platform for teams and professionals, offering shared inboxes, unlimited addresses, conversation notes, and workflow statuses. It is a self-hostable alternative to hey.com, front.com, and missiveapp.com, built with Next.js, React, and Hono.

Use cases

  • manage shared team inboxes like support@ and sales@
  • replace hey.com or front.com with a self-hosted email tool
  • collaborate on email conversations with notes and assignees
  • track email workflows with statuses
  • create unlimited email addresses for a business
  • host my own modern email client

When to choose

  • your team handles email collaboratively and needs shared inboxes
  • you want a self-hosted, open-source alternative to hey.com or front.com
  • you need unlimited email addresses with per-email workflows

When to avoid

  • you only need a simple personal email client
  • you require full legacy email features like advanced filtering rules
  • you cannot self-host and don't want a hosted subscription
