A static analysis tool that enforces secure coding practices and best practices for Python.
Dlint is a static analysis tool for Python that helps developers identify insecure coding patterns and enforce best practices. It extends Flake8 with specialized rules focused on security, such as detecting dangerous functions like `exec` or `eval`. The tool aims to prevent security vulnerabilities by providing actionable feedback during development.
Python developers and teams who prioritize code security and want to integrate automated security checks into their workflow. It's particularly useful for projects handling sensitive data or requiring compliance with security standards.
Developers choose Dlint because it integrates seamlessly with Flake8, making adoption easy, and focuses specifically on security linting—a niche not fully covered by general-purpose linters. Its plugin system also allows teams to customize rules for their specific security needs.
Dlint is a tool for encouraging best coding practices and helping ensure Python code is secure.

Specifically detects insecure patterns like exec and eval usage, as shown in the CLI example where it flags DUO105 for exec, providing actionable security feedback.
Builds on Flake8's ecosystem, allowing easy adoption via existing commands and plugins, evidenced by the install check showing dlint as an installed Flake8 plugin.
Supports inline feedback in editors like VS Code and PyCharm via plugins, and integrates into pipelines, as highlighted in the README's editor integration and CI/CD sections.
Enables extending with custom rules using a simple naming convention (e.g., module names starting with dlint_plugin_), demonstrated in the Custom Plugins section with an example plugin.
Effectiveness is tied to Flake8's limitations and ecosystem; projects not using Flake8 may find integration cumbersome or redundant with other linters.
Focuses primarily on security, so it lacks built-in rules for style, formatting, or other code quality aspects, requiring additional tools like pycodestyle or black for full linting coverage.
Security rules can flag legitimate uses of dynamic features (e.g., exec in controlled environments), necessitating manual overrides or custom plugins to avoid noise.
