The application can be downloaded from Here you'll find binary releases for all supported platforms. See below for platform specific instructions. If you run into any problems please consult the Troubleshooting section below.



The primary distribution-independed way to install is to use the flatpak build. This is maintained in it's own repository, however a pre-built binary can be downloaded and installed from flathub which also has a setup guide for many Linux platforms.

Arch Linux

WARNING: Currently the AUR package compiles from latest master. This can be more recent as the latest release, introduce new features but also new bugs.

If you have a AUR helper like yay installed, you can install it by running yay -S deltachat-desktop-git and following the instruction in your terminal.

Otherwise you can still do it manually:

# Download the latest snapshot of the PKGBUILD

# extract the archive and rm the archive file afterwards
tar xzfv deltachat-desktop-git.tar.gz && rm deltachat-desktop-git.tar.gz

# cd into extracted folder
cd deltachat-desktop-git

# build package
makepkg -si

# install package (you need to replace <version> with whatever version makepkg built)
sudo pacman -U deltachat-desktop-git-<version>.tar.xz

Mac OS


$ brew install --cask deltachat


Simply install the .dmg file as you do it with all other software on mac.

If you are getting an OpenSSL error message at the first start up you need to install OpenSSL.

$ brew install openssl

From Source

This is mostly for development purposes, this won't install/integrate deltachat into your system. So unless you know what you are doing, we recommend to stick to the methods above if possible.

# Get the code
$ git clone
$ cd deltachat-desktop

# Install dependencies
$ npm install

# Build the app (only needed on the first time or if the code was changed)
$ npm run build

# Start the application:
$ npm start


This module builds on top of deltachat-core-rust, which in turn has external dependencies. Instructions below assumes a Linux system (e.g. Ubuntu 18.10).

If you get errors when running npm install, they might be related to the build dependency rust.

If rust or cargo is missing: Follow the instruction on to install rust and cargo.

Then try running npm install again.

Make sure that your nodejs version is 16.0.0 or newer.

If you still get errors look at the instructions in the deltchat-node and deltachat-rust-core README files to set things up or write an issue.

Configuration and Databases

The configuration files and database are stored at application-config's default file paths.

Each database is a SQLite file that represents the account for a given email address.
