Sleuth is a deployment tracker that offers a single-button solution for preventing unwanted changes in production environments. The platform provides deployment locking features, which can be used to prevent pull requests from merging into main branches and notify the team via Slack or other chat applications. Deployment locking can be useful during incidents, weekends, key customer demos, or when a large deployment requires soaking time. Sleuth also supports automatic locking of deployments when there are unreleased changes on production branches. The platform is easy to set up and can track deployments automatically or via API notifications.
