Self-hosted alternatives to Proton Mail
Proton Mail is an email service based in Switzerland that encrypts messages end to end and offers a calendar, aliases and custom domains. One listed app does its main job and runs in your own Cloudflare account.
Each answer comes from the app’s README and source code, compared with the features Proton Mail describes on its own site.
