Building an open-source AgentMail alternative with Cloudflare Workers is an interesting approach, especially for developers who want more control over their email infrastructure. Using serverless components could also make the project easier to deploy and scale without maintaining a traditional backend.
I like the tradeoff here. For agent mail, owning the inbox feels way better than adding another hosted service to trust. Cloudflare Workers is a pretty natural fit for this too.
Really interesting project! The combination of AI agents, open-source development, and Cloudflare Workers shows how quickly developers can build scalable solutions without heavy infrastructure. Love seeing more flexible and transparent alternatives emerge in the AI ecosystem. Great work sharing this!

"An address nobody has created is treated differently", the ALLOW_UNKNOWN_INBOX flag is the one config choice I'd actually lose sleep over here. Leave it open on a catch-all and you've built an infinite free inbox generator for anyone who knows your domain, not just your own agents.
