Stack detection
Deployxa reads your repository and picks the runtime, build and start commands. Override any of them in project settings.
Deploy Flask on Deployxa.
Deploy Flask microservices and REST APIs with production Gunicorn process management, HTTPS, and health checks.

01 / Quickstart
Deploy from your terminal.
Install the CLI and deploy the Flask project in your current directory, or connect the repository in the console for push-to-deploy.
- Typical database: PostgreSQL with SQLAlchemy
- Build and start commands can be overridden
- Secrets stay out of build logs
$ npm install -g @deployxa/cli$ deployxa login$ deployxa deploy
02 / Guide
How Flask goes to production.
- 01 /
Connect the repository
Deployxa detects requirements.txt or pyproject.toml and provisions an isolated Python runtime.
- 02 /
Configure WSGI entrypoint
Specify your Gunicorn command (e.g. gunicorn -w 4 -b 0.0.0.0:5000 app:app) in Deployxa settings.
- 03 /
Attach database
Connect managed PostgreSQL; DATABASE_URL is injected into environment.
- 04 /
Promote
Health-checked and served over global edge proxy with automated TLS.
03 / Configuration
Environment variables.
Set these in project settings. Values are never written to build logs.
| Variable | Purpose | Example |
|---|---|---|
FLASK_ENV | Application runtime environment | production |
SECRET_KEY | Cryptographic session signing secret | sec_... |
DATABASE_URL | PostgreSQL connection string | postgresql://... |
04 / Included
What every deploy gets.
Isolated builds
Every push builds in its own sandbox with cached dependencies and layers.
Managed databases
Attach PostgreSQL, MySQL or Redis and the connection details are injected as environment variables.
HTTPS by default
Every deploy gets a deployxa.online URL with a Let's Encrypt certificate; custom domains too.
Health-checked releases
Traffic only switches to a release that passes its health check, and earlier releases stay available for rollback.
Push to deploy
Connect GitHub, GitLab or Bitbucket and each push to your branch ships a new release.
05 / FAQ
Flask questions.
How is static content served?
WhiteNoise can serve static files directly, or the edge proxy caches them automatically.
Can I run background Celery tasks?
Yes, Celery workers can be configured as background worker services.
