How to use this developer tool

Paste a Django file or a multi-file project sample.
Select the project scope and optional framework version.
Run the checker.
Review errors, warnings, passed assumptions, and unresolved references.

What this developer tool does

The checker looks for common Django configuration omissions, model conventions, URL naming issues, and deployment-sensitive settings.

Django file detection → settings/model/URL rules → environment-neutral classification → report

It does not run manage.py check, inspect migrations on disk, connect to the database, or import the project.

Example

A production-oriented settings file with DEBUG = True and an empty ALLOWED_HOSTS list produces explicit configuration warnings.

Tips for better output

Include settings.py, models.py, and urls.py together.
Add file markers so findings include accurate filenames.
Use the Validator for strict pass/fail rule sets.
Use the Inspector for performance and deployment analysis.

FAQ

Does it run manage.py check?

No. It applies static browser-based checks to the supplied source.

Can it inspect settings.py?

Yes. It checks common security, static, media, timezone, and host settings.

Does it validate migrations?

It can note migration references in supplied text but cannot inspect migration state or the database.

Can it detect model issues?

It detects common field and model conventions such as missing __str__ and mutable defaults.

Is the project uploaded?

No. Processing remains local in the browser.
