First-install notes

Start Monica with Docker on port 8080 Run the official Monica Docker command with -p 8080:80, which tells Docker to make container port 80 available as your computer’s port 8080, then open http://localhost:8080. This is what lets your browser reach Monica; without it, the app will not open. source
Set up email before inviting people Start Docker with an email-sending setting, like -e MAIL_MAILER=log for testing, or point Monica to a real mail server for real use. Without working email, invitation and verification messages won’t arrive, so people may not be able to join or get back in. source
Create and verify your account During first setup, create your account with a name, email, and password, then click the verification link Monica emails you. Without that step, your account may not be ready to use and you may not be able to reset your password later. source

Common questions

The main branch is in development; which branch should I use for a stable self-host?

Use the 4.x branch for the stable and current version. The main branch is a development beta.

Which host port should I expose when running the official Docker setup?

Run the official Docker command with -p 8080:80. That maps container port 80 to host port 8080.

What email setting should I configure in Docker before inviting people?

Use MAIL_MAILER=log only for testing, and point Monica to a real mail server for real use. Without working email, invitation and verification messages will not arrive.

Can one Monica instance support multiple users and separate vaults?

Yes, Monica supports multiple vaults and users. It also supports labels to organize contacts.
