Django on Fly.io

Fly.io publishes its own guide for deploying Django.

Python web framework with an ORM, admin interface and long-running server process.

01.

What Django needs.

Every host claims to run Django, so the claim on its own decides nothing. These are the things Django actually requires from the platform underneath it, and what Fly.io publishes about each. Fly.io documents 3 of the 4.

Persistent processes

Not documented

Django is served by a WSGI or ASGI worker that stays up. Celery workers are a second long-running process alongside it.

Managed databases

Supported

Django's ORM, migrations and admin all assume a real relational database. Postgres is the default assumption in its own documentation.

  • Fly.io pricing ↗

    “The price of running Fly.io Managed Postgres depends on your selected Managed Postgres Plan and the amount of storage your Postgres cluster has.”

Managed connection pooling

Supported

Django opens a database connection per worker. Without pooling, a modest traffic spike exhausts Postgres connection slots long before it exhausts CPU.

Sources (1) →
  • Cluster configuration options ↗

    “All Managed Postgres clusters come with PGBouncer for connection pooling, which helps manage database connections efficiently. You can configure how PGBouncer assigns connections to clients by changing the pool mode.”

Scheduled jobs

Limited

Management commands are how Django does recurring work. With no scheduler you need a second service whose only job is to trigger them.

  • fly machine run · Fly Docs ↗

    “Use the --schedule flag to set the Machine's config.schedule property, which starts the Machine on a fuzzy hourly, daily, weekly, or monthly cycle.”

The requirement and the reason it matters are ours. Every value beside them was read from Fly.io's own pages — expand a source to see the sentence it came from.

02.

What Fly.io documents.

Fly.io publishes its own guide for deploying Django.

Fly.io is a great place to run your Django application. fly launch can detect, configure and deploy Django apps.

03.

What it costs to run there.

Pricing model
Usage-based, no compute plan tiers
When you exceed a cap
No plan cap to exceed — Fly bills per second for provisioned resources. The only documented enforcement is unspecified automated scaling limits, which surface as an error message (platform-wide, all plans)
Regions
18 regions

  • Fly.io pricing ↗

    “Plans get complicated, so we just charge based on usage. Billing is based on the resources provisioned for your apps, pro-rated for the time they are provisioned.”

  • Fly.io regions ↗

    “You can host your apps in any of the following regions — including ams (Amsterdam, Netherlands), nrt (Tokyo, Japan) and syd (Sydney, Australia).”

04.

Whether it suits you.

Workloads that ship as Docker images and need placement in particular regions. Billing is purely usage-based with no plan tiers, which suits spiky or region-pinned traffic better than a flat monthly fee.

Consider something else if…

You want a predictable flat bill rather than charges that track the resources provisioned for each app.
