I originally built it for myself. I wanted multiple addresses and domains - support@, sales@, personal addresses, etc. - without paying for a separate mailbox for every address or running a mail server.
It uses Cloudflare Workers, Email Routing/Sending, D1 and R2.
HQBase gives you one inbox for multiple domains and addresses, team invites with granular inbox access, a PWA with push notifications (including iPhone), and an MCP server.
Setup takes about 2-3 minutes, and the infrastructure stays in your Cloudflare account.
The project is AGPL-3.0 and fully open source.
Would love feedback and any features you'd like to see.
