GitHub

Overview

Install the Nullify GitHub App to connect Nullify to your repositories. Nullify works with GitHub.com and GitHub Enterprise. Installation instructions differ for cloud and self-hosted deployments — see the Enterprise Tier section for step-by-step guides.

Nullify posts updates asynchronously so developers stay inside their existing workflow.

What Nullify does with GitHub

• Pull request reviews. When a pull request is opened, reopened, or updated, Nullify reviews the changed code and posts its findings back to the pull request as review comments and a Nullify check. When a PR is merged or closed, Nullify reconciles the state of any of its own autofix pull requests.

• Push scanning. Pushes are scanned, and pushes to the default branch refresh the repository's baseline so dashboards and finding counts stay current.

• Autofix pull requests. Nullify opens fix PRs for eligible findings, keeps them green through CI, responds to review comments, and assigns reviewers. See Remediations.

• Comment-driven discussion. Replies on a Nullify pull request — or an @mention of Nullify on any PR — are routed back so it can respond in-line.

Events handled

Nullify subscribes to the events it needs to review and remediate — including push, pull-request, pull-request-review and review-comment, issue-comment, check-run and check-suite, status, repository, and the app installation lifecycle. Settings such as the CI/PR gate, ticketing thresholds, and notification destinations are configured in the Nullify dashboard under Configure, not in a file in your repository.
