Secure Coding Checklist

Generate a secure coding checklist

Writing secure code means remembering the pitfalls of your language, and a checklist keeps them in view. This tool generates secure coding checklists for JavaScript, Python, Java and PHP, so you have the language-specific security concerns at hand while you work.

Why a checklist changes behaviour

Developers know security matters but forget specifics under deadline pressure, which is how avoidable vulnerabilities ship. A concrete checklist for your language, the input handling, the dangerous functions, the framework-specific concerns, turns vague awareness into specific actions to verify. Using it during development and review is one of the cheapest, most effective ways to reduce vulnerabilities, because it catches the well-known, common issues systematically rather than relying on memory. This supports writing more secure software from the start.

Security you can check off

It runs entirely in your browser, so nothing you paste is uploaded and the result is yours to copy straight into a project. Because it works client-side, you can use it on private code and data without anything leaving your machine.
