Python hosting that builds and runs your app for you
Push your Python source and Velixir builds it into a container, ships it to managed Kubernetes, and keeps it running with autoscaling and zero-downtime deploys. No Dockerfile, no gunicorn tuning, no ops team required.
Why deploy Python on velixir
- No Dockerfile and no requirements.txt guesswork: Velixir detects your Python project, installs from requirements.txt, Poetry, Pipenv, or PDM, and builds the image server-side.
- Django, Flask, and FastAPI run the way you expect: bind to the port Velixir gives you and the platform handles the WSGI/ASGI process, rolling deploys, and instant rollback.
- Managed Postgres and Valkey included and billed hourly in EUR, so your Django ORM or SQLAlchemy app and your Celery or RQ queues get a real database and cache without extra vendors.
- EU data residency with unmetered bandwidth and no egress fees, so data-heavy Python APIs and ML inference endpoints stay cheap and GDPR-friendly.
Works with your stack
Popular Python frameworks and runtimes deploy as-is, no adapters.
Runtime versions
Pick your version and we pin the exact runtime for every build.
Legacy (past upstream end-of-life, still runnable for lift-and-shift):
From Python source to production in three steps
Push your source
Git push, velixir deploy, a dashboard upload, or a connected GitHub repo. No Dockerfile.
We build it server-side
Velixir detects Python, installs dependencies, and builds a container image on our infrastructure.
It goes live
Managed Kubernetes runs it with autoscaling, zero-downtime rolling deploys, and one-click rollback.
Python hosting FAQ
Which Python versions does Velixir support?
Velixir defaults to Python 3.13 and supports every release down to 3.10. Legacy projects can still run on 3.9, 3.8, or even 2.7, so you can lift older services onto the platform and modernize on your own schedule. Pin the version you want and the build pipeline uses it.
Do I need a Dockerfile or to build the image myself?
No. You push source (git push, the velixir deploy CLI, a dashboard upload, or a connected GitHub repo) and Velixir builds the container image server-side, pushes it to a private registry, and runs it. There is no Dockerfile to write, no local Docker, and no build config to maintain.
How are dependencies installed?
Velixir detects your dependency manifest automatically and installs from requirements.txt, Poetry (pyproject.toml plus poetry.lock), Pipenv, or PDM. Native wheels that need system libraries build during the server-side step, so packages like psycopg, Pillow, and numpy install cleanly without you configuring a build environment.
Can I run Django or FastAPI in production with a real database?
Yes. Django, FastAPI, Flask, and any WSGI or ASGI app run on managed Kubernetes with autoscaling and zero-downtime rolling deploys. Managed Postgres and Valkey (Redis-compatible) are included and billed hourly in EUR, covering your ORM, your cache, and Celery or RQ workers. Toggle on high availability for a warm-standby replica when you need it.
Deploy your Python app in under two minutes
Push your code and Velixir builds, publishes, and deploys it to the region you pick, EU Central or NA East, with managed Postgres and Valkey a click away. No Docker, no YAML, and your first month's on us, up to €14.99.
