1. Linters and Code Quality Checkers:

    • flake8: A popular Python linting tool that checks your code against coding standards like PEP 8. It also has several plugins available to extend its functionality.

    • pylint: Another Python source code, bug, and quality checker. It offers more checks than flake8 but is also more verbose and opinionated.

    • bandit: A tool designed to find common security issues in Python code.

    • mypy: A static type checker for Python. Helps catch type errors before runtime, given that Python is dynamically typed.

  2. Security and Dependency Checkers

  3. Security and Dependency Checkers:

    • safety: Checks your installed dependencies for known security vulnerabilities.

    • pyup: A service that continuously updates your project’s dependencies and sends pull requests whenever a dependency is outdated or has known vulnerabilities.

  4. Error and Crash Monitoring Tools:

    • Sentry: A powerful error tracking platform that can be integrated with Django (and many other platforms) to capture and analyze runtime errors and exceptions.

    • Rollbar: Like Sentry, it’s used for real-time error monitoring and alerting.

  5. Performance and Optimization Tools:

    • Django Debug Toolbar: Provides a set of panels displaying various debug information about the current request/response, helping during the development process.

    • Silk: A live profiling and inspection tool for Django. It intercepts and stores HTTP requests and database queries before presenting them in a user-friendly UI.

    • nplusone: Helps to detect the n+1 queries problem in Django, which can be a common performance pitfall.

  6. Testing and Coverage:

    • pytest: A popular testing framework for Python, which can be used with Django projects to run tests and generate reports.

    • coverage: Measures code coverage of Python programs, helping ensure that your tests are comprehensive.

  7. Continuous Integration Services:

    • Travis CI: A CI/CD platform that can run tests, linters, and other checks whenever you push to your repository.

    • GitHub Actions: Provides CI/CD capabilities directly within the GitHub platform, allowing for automation of workflows, including testing and deployment.

    • CircleCI: Another CI/CD platform that integrates with popular VCS platforms and allows for complex workflows.

  8. Django-specific Linting:

    • django-lint: A tool for flagging potential issues in Django applications.
