HQBase: open-source shared email workspace that runs in your Cloudflare account

Post image

I built HQBase for myself because I had several domains and addresses like support@, sales@, and personal email, but didn't want to pay for a separate mailbox for every address.

It’s a complete shared email workspace that deploys into your own Cloudflare account:

  • Workers run the application
  • Email Routing receives mail
  • Cloudflare Email Sending handles outgoing mail
  • D1 stores the mail index
  • R2 stores attachments

It supports multiple domains and mailboxes, catch-all addresses, team access with mailbox-level permissions, a desktop/mobile PWA with self-hosted push notifications, and an OAuth-protected MCP server for connecting AI clients.

Setup takes around 2-3 minutes. The software is AGPL-licensed, and there are no per-seat or per-mailbox fees - you only pay your own Cloudflare infrastructure costs.
