Clace is an application server for deploying containerized web apps, specifically targeting internal tools. It supports deploying apps directly from Git repos, which aligns with version control integration. It also mentions OAuth and SSO for authentication, covering access control and security. While it doesn't explicitly state 'drag-and-drop UI builder' or 'API & Database Integrations' in the same way Retool does, it does mention 'Automatically generate a form based UI for backend actions' and 'Integration with secrets managers, to securely access secrets', implying some level of integration capabilities. The use of Starlark for backend app code indicates code customization. It also focuses on deployment of containerized apps, which aligns with flexible deployments.
