Baserow

Baserow is a strong match for the Retool concept. It explicitly offers a no-code platform for building databases and applications, which aligns with the core value proposition. The website highlights features such as a 'Database Builder' and 'Application Builder' which directly correspond to the drag-and-drop UI builder and data connectivity aspects. It also mentions API integrations, security features like role-based access control, and flexible deployment options (cloud or self-hosted). Furthermore, Baserow emphasizes its AI capabilities for data enrichment and automation, and offers workflow automation. While it doesn't explicitly mention 'code customization' in the same way Retool does, its 'Developers' section with API access and plugin creation suggests extensibility that could allow for custom logic. The 'Prebuilt React Components' are implied through its template library and visual builder.
