OpenInbox

OpenInbox

Self-hosted free business email

Description

Business email charges per seat per month, and the bill grows fast with a team. OpenInbox deploys sending and receiving into your own free Cloudflare account, with no limit on users, mailboxes, aliases or domains.

It is written in TypeScript and made of one Cloudflare Worker and one D1 database, deployable in one click through Deploy to Cloudflare. The UI is a familiar three-pane mail client with shared inboxes and team collaboration.

Features



Your own domains:send and receive on your domain with unlimited mailboxes and aliases.

Cloudflare free tier:depends only on a Worker and D1, no extra server.

Team inbox:several people work one inbox with assignment and labels.

MIT open source:the code is fully open and yours to modify.
