FAQs for the GitHub App

What programming languages are supported?
The currently supported languages are C#, CSS/SCSS, Go, Java, JavaScript/JSX, Python, Rust and TypeScript/TSX. SemanticDiff can also be used with the data exchange formats JSON and gettext .po files.
Can I try the GitHub App without installing it?
Yes, you can go to and enter the URL of any public pull request to test it. Some features, such as writing comments, are only available if the repository maintainer has enabled our App.
How do plans relate to GitHub repositories?
Each plan/license is associated with exactly one installation of the GitHub App. The app can be installed on either a GitHub organization or a GitHub user account (hereafter referred to as the owner). The plan assigns a certain number of seats to the owner. The seats are shared across all repositories owned by that owner.
What are seats?
Our GitHub App requires seats for all developers whose pull requests in private/internal repositories are to be analyzed. Free seats are assigned automatically the first time a pull request from a GitHub user is analyzed.
What happens when I run out of seats?
If you run out of seats, only pull requests from authors with seats assigned will be analyzed. You can either upgrade your plan or remove an existing seat assignment to make room for new pull request authors.
Does the GitHub App work with GitHub Enterprise?
Our GitHub App works right out of the box with GitHub Enterprise Cloud. If you are using the self-hosted GitHub Enterprise Server, please contact us to determine the best solution for your needs.
Do you offer plans for students and non-profit organizations?
Depending on the size of your team, you may qualify for a free plan or a discount. Please contact us from your student/work email with proof of eligibility, details about the project, and how many seats you need.
How do you keep my GitHub repositories private?
To view the contents of private repositories in our GitHub App, users must sign in using GitHub OAuth. All communication with GitHub is then done through their OAuth token, which enforces permission checks.
How do you keep my code secure when using the GitHub App?
We take code security very seriously and have implemented various measures to protect your data, such as encryption, audit logs, and more. Feel free to reach out to to learn more.
