The easiest way to run Email Specter is with Docker Compose:

git clone https://github.com/maileroo/email-specter.git
cd email-specter
cp .env.example .env
docker-compose up -d

Access Email Specter at http://localhost/ (or your server's IP).

If you prefer a non-container solution, use Ansible. The playbook has been tested with Ubuntu 24.04 LTS.

git clone https://github.com/maileroo/email-specter.git
apt install ansible git -y
ansible-galaxy install trfore.mongodb_install

Edit the inventory file and set your public IP:

public_ip: "127.0.0.1"

Run the playbook:

cd email-specter/ansible/scripts
chmod +x run.sh
./run.sh

Access Email Specter at http://<public_ip>/.

1. Install dependencies:
   • MongoDB 4.0+
   • Node.js 22
   • Go 1.24
2. Clone the repository
3. Copy .env.example to .env and configure
4. Build and run the backend:

   go build .
   ./email-specter

5. Build and run the frontend:

   cd frontend
   npm install
   npm run build
   npm run start

Once Email Specter is installed and running, you can access it from your web browser at http://{{ public_ip }}/.

You will be prompted to create an admin user on the first visit. After that, you can log in with the credentials you set.
