The short version

  • Each has a real cost: Django does not fully support asynchronous database access; Preact compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose
  • They diverge on capability: Django covers Model-View-Template (MVT), Preact covers 3kB runtime.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Django

  • Does not fully support asynchronous database access
  • Monolithic design can feel restrictive for small-scale or lightweight applications
  • Batteries-included approach adds overhead if features are not needed
  • Slower framework evolution due to backward compatibility requirements

Preact

  • Compatibility through preact/compat is good but not total, and some React libraries break in ways that are hard to diagnose
  • Behavioural differences from React exist in edge cases, particularly around event handling
  • A much smaller community, so unusual problems have fewer existing answers than React

Answered from the vendors’ own pages

Django: What databases does Django support?

Django natively supports PostgreSQL, MySQL, SQLite3, and Oracle databases through its ORM, allowing developers to switch databases without rewriting code.

Source
Preact: Is Preact free?

Yes, open source under the MIT licence.

Django: How does Django handle database schema changes?

Django includes a built-in migration system. Developers use makemigrations to create migration files and migrate to apply changes to the database schema.

Source
Preact: Can I use React libraries with Preact?

Most, through the preact/compat layer. Compatibility is good but not complete, so libraries relying on React internals can break.

Django: Does Django support asynchronous programming?

Django added basic async/await support, but full asynchronous database access remains limited. The framework does not fully support asynchronous programming, which can be a limitation for real-time applications.

Source
Preact: Why choose Preact over React?

Bundle size, almost always. If payload is not a binding constraint, React’s ecosystem is usually the better trade.

Django: Is Django free and open source?

Yes, Django is free and open-source software maintained by the Django Software Foundation, founded in June 2008.
