P42+ reviews code together with another developer.

Automate Code Reviews

Pull requests are a great way to exchange knowledge and ensure high code quality. However, experienced engineers should focus on the big picture and not waste time reviewing code quality details repeatedly.

P42+ reviews your pull requests automatically and suggests improvements that make your code cleaner and more modern, so you and your teammates can learn the latest best practices, enjoy high-quality code, and save time. Learn more...

P42+ shows you where in your codebase old code is hidden.

Identify Outdated Code

Codebases evolve over many years, and old patterns, outdated best practices, and tech debt often accumulate in many areas.

But working with code written with outdated syntax and patterns from 5 or 10 years ago requires a taxing mental shift for senior developers. It is even harder for new developers who are used to modern code.

P42+ scans and visualizes your codebase, so you can identify and modernize problematic code areas before they lead to developer frustration, missed deadlines, and unnecessary bugs.

P42+ upgrades your codebase while you relax.

Modernize Your Codebase

It is dull and painful to migrate an existing codebase to follow new patterns and use new syntax - and it can take weeks and months.

With P42+, you can apply code migrations to your files and folders in bulk in the VS Code extension and review and test the changes immediately in your development environment. Upgrading your code has never been this easy.

"Legacy code is a growing problem in the JavaScript world. I've created P42 to help developers modernize code easily, so they can enjoy implementing new features with the latest standards."
Lars Grammel
Founder of P42
