Why does style matter?

Convention

Defining and sticking with a style guide helps reduce the amount of decisions that developers need to make when writing code, helping to keep their focus on logic, not semantics and formatting.

Consistency

When every line of code is written in the same style, the whole codebase becomes easier to read, understand and de-bug. It also helps prevent areas of the codebase from being “owned” by one person's unique style vs. the team.

Awesomeness

A clean codebase is a reflection of a cohesive team. It gives the impression of a team working well together towards a common goal, rather than individual developers working independently.

How it works.

Hound integrates with your existing workflow by reviewing and commenting on code the moment a GitHub pull request is opened or updated.

Save time, get better reviews.

Automated style checking with Hound gives developers more time to give the kind of code review that humans are best at giving.

Use our guides or configure your own.

Hound's default style guides build upon accepted industry standards and are the result of years of utilization in software projects at thoughtbot. Have your own style guide or need to modify the default? Hound provides the ability to customize your guides to best suit your team's needs.
