Hey r/foss!

I'd like to share a project I've been working on for the past few months. It's called HQBase, and it's a self-hosted email workspace that runs in your own Cloudflare account. It uses Cloudflare services for inbound and outbound email, storage, compute, etc.

I originally built it for myself but at this point I think it may be one of the easiest and cheapest ways to manage multiple email addresses across multiple domains.

It took me a while to get to a v1 that I felt good about. I put a lot of thought into:

• A very simple setup wizard using OAuth
• A PWA with self-hosted push notifications
• Granular permissions for invited users
• Cryptographically signed updates

This is only the first solid version, and while I have a pretty ambitious roadmap, I'd love for you to try it and tell me what you think should come next! :)

I have a bunch of side projects and domains, and I kept running into the same problem: every new project meant another email subscription, usually priced per mailbox.

So I built HQBase - a fully open-source email workspace that deploys into your own Cloudflare account.

HQBase itself is free. You just need Cloudflare Workers Paid at $5/month - not $5 per user or mailbox.

You get:

• Multiple domains and email addresses
• Send + receive email
• Multiple users with granular access
• PWA with push notifications
• MCP server
• 2–3 minute setup
• AGPL-3.0 open source

I also just really like what Cloudflare has built. Workers, Email Routing, Email Sending, D1 and R2 together make it possible to run something like this entirely inside your own account. 🧡

I built HQBase for myself, then decided to open source it.

Would love feedback from other people juggling multiple side projects/domains.
