What is Retool?
Retool is a low-code platform for building internal tools and business applications, made by Retool Inc. It enables developers and non-technical users to create production-ready applications by connecting to databases, data warehouses, and external APIs without writing code from scratch. Users assemble interfaces visually, query data, and orchestrate workflows through a browser-based interface that ships enterprise-grade security controls out of the box.
The platform serves data teams, operations groups, engineering teams, and business users across industries including financial services, manufacturing, supply chain, and healthcare. Retool integrates with PostgreSQL, MySQL, MongoDB, Salesforce, Stripe, Google Sheets, and 500+ other data sources and applications. It offers a visual query builder, pre-built UI components, real-time collaboration, version control, and self-hosting options. The platform includes AppGen, an AI-assisted feature that generates application code from natural language prompts, and an agents capability for building autonomous workflows. Teams deploy applications to managed cloud infrastructure or self-hosted environments with centralized governance, permission inheritance, and audit logging built in.
Retool operates on a freemium model: the core builder and unlimited apps are free for small teams, while enterprise editions add role-based access control, SSO, audit logs, and dedicated infrastructure. Pricing scales with workspace users and deployment options. According to case studies on their site, organizations including DoorDash, Ramp, and major manufacturers report time savings ranging from 10x faster development cycles to millions of dollars in operational cost reduction and thousands of hours saved annually.
The platform competes with other low-code application builders like Bubble, OutSystems, and Mendix, though Retool emphasizes internal tool velocity and data connectivity over web application development. It also overlaps
