Sleuth is a SaaS deployment tracker that pulls deployments from source repositories, feature flags, and other sources, in addition to pushes via curl. You can see Sleuth used to, well, track Sleuth at https://app.sleuth.io/sleuth
I can also recommend Sleuth. We use it at our company and the integration is very good. Their team is constantly working on new features, integrations and better UI.
