Its biggest pro is the centralized analysis for multiple different languages. Typically you'd need to set up and configure a linter for JS, Java, Python, etc separately, per repo but codescan works out of the box on all the major languages and provides a single UI for managing the rules. It also is simple to set up and integrate into CI/CD and takes away the pain of having to do that integration for each language pipeline. Another pro is that it works at the project level so you can have multiple repos, each of different languages (or mixed) which all have their own coverage and health grade. You can also customize each ruleset (self hosted) for each language to suit the teams needs. Some people enjoy trailing commas and the others are just wrong.
