Drift Detection + Remediation

Drift Detection + Remediation helps you continuously compare real infrastructure against your IaC definitions, detect unexpected changes, and drive remediation through the same PR-based workflow your team already uses.

Prerequisites:

• Set up your OpenTaco account
• Set up GitHub App
• A working PR Automation setup with a functional GitHub Actions workflow

Enable drift detection

To activate drift detection, you must enable it at both levels:

In settings, toggle **Enable drift detection** on.

In the projects page, toggle **Drift** on for each project.

Configure notifications, schedule, and status

Configure Slack notifications using a webhook URL.

Run drift detection on preset intervals (for example, hourly or daily), or use a custom crontab.

OpenTaco runs a `plan` workflow (via GitHub actions) for selected projects on your default branch. If the plan is not clean, OpenTaco sends a Slack notification and updates drift status in the app.
