Flask

Combine filters →

Flask is a minimal Python web framework, so hosting it is hosting Python: a WSGI server such as Gunicorn behind a proxy, a virtual environment, and a way to run a database migration on deploy. There is nothing framework-specific for a provider to support. A host naming Flask is announcing Python, and a platform that names Django runs Flask the same way.

4 providers document support for Flask, listed alphabetically. Mostly platform as a service, infrastructure as a service and shared hosting, of 6 categories in all. 116 records do not record this field, and cannot appear here either way.

L

  • Leapcell

  • Liara

Do I need special hosting for Flask?

In most cases, no. Flask runs on any host that supports its runtime. This list is shorter than that: it holds the providers that document Flask themselves, with an installer, a guide or a maintained image. Other hosts may run it without mentioning it.

What should I check before hosting Flask?

The runtime versions on offer, how deploys work, whether there is a shell for command-line tools, where cron jobs run, and which databases come managed. Check backups too, and how to move away later.

Who is the best Flask hosting provider?

We can't tell from here. A host that suits a small agency site can be wrong for an API with users in Asia and Europe. The list is alphabetical and nobody paid for a place on it. The guide covers what to compare.
