Baserow

Baserow is an open-source no-code platform for building databases and applications. It allows users to structure, visualize, and manipulate data, create custom applications, and automate workflows through various integrations. The platform offers both cloud-hosted and self-hosted deployment options, emphasizing data security and compliance.

Baserow is a strong match for Retool's concept. It explicitly offers an 'Application Builder' for creating custom applications without code, which aligns with the drag-and-drop UI builder. It provides extensive API and database integrations, including REST API, webhooks, and connections to various services like Jira, HubSpot, and PostgreSQL. The platform supports self-hosting (Docker, AWS, Helm) and cloud deployments, covering flexible deployments. Security features like role-based permissions, SSO, and audit logs are clearly stated. While not explicitly 'code customization' in the sense of embedding JavaScript/SQL directly into UI components, Baserow's API-first approach and plugin system allow for significant customization and extension, which serves a similar purpose for developers. The AI features and partner portal capabilities also align with 'other' features.
