- Install to cloud
- Upgrade doccano
System requirements
You can install doccano on a Linux, Windows, or macOS machine running Python 3.8+.
Web browser support
doccano is tested with the latest version of Google Chrome and is expected to work in the latest versions of:
- Google Chrome
- Apple Safari
If using other web browsers, or older versions of supported web browsers, unexpected behavior could occur.
Port requirements
doccano uses port 8000 by default. To use a different port, specify it when running doccano webserver.
Install with pip
To install doccano with pip, you need Python 3.8+. Run the following:
pip install doccano
After you install doccano, start the server with the following command:
# Initialize database. First time only.
doccano init
# Create a super user. First time only.
doccano createuser --username admin --password pass
# Start a web server.
doccano webserver --port 8000
In another terminal, run the following command:
# Start the task queue to handle file upload/download.
doccano task
Open http://localhost:8000/.
Install with Docker
doccano is also available as a Docker container. Make sure you have Docker installed on your machine.
To install and start doccano at http://localhost:8000, run the following command:
docker pull doccano/doccano
docker container create --name doccano \
-e "ADMIN_USERNAME=admin" \
-e "ADMIN_EMAIL=admin@example.com" \
-e "ADMIN_PASSWORD=password" \
-p 8000:8000 doccano/doccano
Next, start doccano by running the container:
docker container start doccano
To stop the container, run docker container stop doccano -t 5
.
All data created in the container persist across restarts.
Build a local image with Docker
If you want to build a local image, run:
docker build -t doccano:latest . -f docker/Dockerfile
Install with Docker Compose
You need to install Git and to clone the repository:
git clone https://github.com/doccano/doccano.git
cd doccano
To install and start doccano at http://localhost, run the following command:
docker-compose -f docker/docker-compose.prod.yml --env-file ./docker/.env.example up
You can override the default setting by rewriting the .env
file.
Install from source
If you want to develop doccano, consider downloading the source code using Git and running doccano locally. First of all, clone the repository:
git clone https://github.com/doccano/doccano.git
cd doccano
Backend
The doccano backend is built in Python 3.8+ and uses Poetry as a dependency manager. If you haven't installed them yet, please see Python and Poetry documentation.
First, to install the defined dependencies for our project, just run the install
command. After that, activate the virtual environment by running shell
command:
cd backend
poetry install
poetry shell
Second, set up the database and run the development server. Doccano uses Django and Django Rest Framework as a backend. We can set up them by using Django command:
python manage.py migrate
python manage.py create_roles
python manage.py create_admin --noinput --username "admin" --email "admin@example.com" --password "password"
python manage.py runserver
In another terminal, you need to run Celery to use import/export dataset feature:
cd doccano/backend
celery --app=config worker --loglevel=INFO --concurrency=1
After you change the code, don't forget to run mypy, flake8, black, and isort. These ensure code consistency. To run them, just run the following commands:
poetry run task mypy
poetry run task flake8
poetry run task black
poetry run task isort
Similarly, you can run the test by executing the following command:
poetry run task test
Did you pass the test? Great!
Frontend
The doccano frontend is built in Node.js and uses Yarn as a package manager. If you haven't installed them yet, please see Node.js and Yarn documentation.
First, to install the defined dependencies for our project, just run the install
command.
cd frontend
yarn install
Then run the dev
command to serve with hot reload at localhost:3000:
yarn dev
How to create a Python package
During development, you may want to create a Python package and verify it works correctly. In such a case, you can create a package by running the following command in the root directory of your project:
./tools/create-package.sh
This command builds the frontend, copies the files, and packages them. This will take a few minutes. After finishing the command, you will find sdist
and wheel
in backend/dist
:
Building doccano (1.5.5.post335.dev0+6be6d198)
- Building sdist
- Built doccano-1.5.5.post335.dev0+6be6d198.tar.gz
- Building wheel
- Built doccano-1.5.5.post335.dev0+6be6d198-py3-none-any.whl
Then, you can install the package via pip install
command:
pip install doccano-1.5.5.post335.dev0+6be6d198-py3-none-any.whl
Install to cloud
doccano also supports one-click deployment to cloud providers. Click the following button, configure the environment, and access the UI.

Upgrade doccano
Caution: If you use SQLite3 as a database, upgrading the package would lose your database.
To upgrade to the latest version of doccano, reinstall or upgrade using pip.
pip install -U doccano
If you need update the database scheme, run the following:
doccano migrate
