Getting Started
Set up Gatecheck in under 5 minutes and get your first AI-powered code review.
Quick Setup
Install the GitHub App
Install the Gatecheck GitHub App on your repositories. The app automatically configures webhooks so Gatecheck receives push and pull request events.
Open GitHub AppsEnroll a repository
Go to the Repositories page and click Enroll on any repo where the GitHub App is installed. This enables CI/CD security scanning for that repo.
Go to Repositories →Trigger your first CI scan
Push a change that touches a file in .github/workflows/, a Dockerfile, or a dependency file. Gatecheck will scan it for security risks and post findings to the dashboard.
View Findings →Open a pull request
Open or update a pull request on an enrolled repo. Gatecheck will automatically run 6 AI agents in parallel to review your code and post a detailed verdict.

Multi-Agent Review
Every PR is analyzed by 6 specialist Gemini agents in parallel — Security, Bugs, Performance, Readability, Best Practices, and Docs. A synthesizer then combines findings into one verdict.
CI Security Gate
A lightweight GitHub Actions step checks the Gatecheck decision API. If blocking findings exist for the commit SHA, the job exits non-zero before any other steps run.
Security Findings
Gatecheck detects secrets, supply-chain RCE patterns (pull_request_target + fork checkout), OWASP Top 10, insecure Docker base images, and more — all without running your code.
Real-time Updates
The Pull Requests dashboard auto-refreshes while a review is running. Watch each agent complete and the final synthesizer verdict appear live.
