Self-hosted · early access

More than email.
A smarter you.

BIDUA Gram is a mail platform you run on your own server: one webmail for mail, calendar, contacts and files, desktop apps for Mac, Windows and Linux, and an installer that sets the server up for you over SSH.

Five pillars

Everything a team needs, in one place.

Each pillar works on its own and shares the same sign-in, the same search and the same look.

1

Mail

Send and receive with SMTP, IMAP and JMAP. Several accounts in one window, with reply, threads and attachments.

2

Calendar

Events, invitations you can accept, maybe or decline, and a free/busy view that shows times only.

3

Contacts

Address books for you and for the company, shared on your terms and withdrawn whenever you like.

4

Files

Folders and files with sharing between colleagues. Access ends the moment the owner withdraws it.

5

Control

An owner portal to add domains and people, plus backups, upgrades and a safe way back if an upgrade fails.

One calm inbox

Quiet on the surface, quick underneath.

The webmail is built to be read for hours: soft light, clear hierarchy, nothing shouting. Switch between accounts with one key and keep each account's mail strictly apart.

  • A light Moon theme and a night theme you can switch to
  • Keyboard shortcuts for switching accounts and searching
  • Works in a browser and as a desktop app
All features
For owners

Install in minutes, not days.

Point the installer at a fresh Ubuntu server. It checks the machine, installs and starts the services, and tells you exactly which DNS records to add. If it is interrupted it continues where it stopped.

For employees

One sign-in, every tool.

Mail, calendar, contacts and files open from the same place. Shared items appear when a colleague shares them and disappear the moment access is withdrawn.
