Softr

Softr is a no-code platform that enables users to build custom web applications, client portals, and internal tools. It provides a drag-and-drop interface, integrates with various data sources and APIs, and offers features for user management, permissions, and workflow automation. The platform aims to simplify app development for businesses without requiring coding knowledge.

Softr is a strong match for Retool's concept as it is a low-code platform for building custom applications, specifically highlighting client and partner portals, which aligns with the 'internal tools' aspect. It offers extensive API and database integrations, a drag-and-drop UI builder, and robust access control and security features. While it emphasizes 'no-code', it does offer 'custom code' for advanced users, fulfilling the code customization requirement. It also supports flexible deployments through PWA and custom domains, and offers features like workflow automation, mobile responsiveness, AI app generation, and custom branding, all of which align with the 'other' features. The focus on building portals for clients and vendors directly matches the 'Partner & Customer Portals' feature.
