Frequently asked questions

What do the top four say they are built for?

Kodus says it is built for growing engineering teams, and Sourcery for Teams that cannot afford to ship bugs. RepoShark says it is built for software development teams monitoring repository health, and Greptile for software development teams seeking automated PR validation.

What should a buyer check before signing up?

RepoShark states that RepoShark limits the free tier to analysing only a single public repository. Greptile states that Greptile operates on a credit system where additional usage incurs extra costs. Those are the limits each AI tool publishes itself, not a full account of any plan.
