Retool Internal Tools Builder

Retool is a low-code development platform for building custom internal business applications and tools. Founded in 2017 by David Hsu (CEO, a Thiel Fellow who dropped out of Stanford), Jing Chen, and Allan Sioson in San Francisco, California. The company has raised over $97 million from investors including Sequoia Capital, Y Combinator, and founders of GitHub, Stripe, and PagerDuty, achieving a $3.25 billion valuation. Retool serves over 10,000 customers including Amazon, NBC, Peloton, and Volvo. Key features: visual app builder: drag-and-drop pre-built UI components (tables, forms, text inputs, dropdowns, buttons, modals, charts, rich text editors, date pickers, file uploads) onto a canvas. Each component can be configured with queries, transformations, and event handlers. Connect any data source: connect to REST APIs, GraphQL APIs, SQL databases (PostgreSQL, MySQL, SQL Server, Oracle), NoSQL databases (MongoDB, DynamoDB, Redis), SaaS tools (Salesforce, HubSpot, Stripe, Slack), and custom data sources via JavaScript code. Write queries in SQL, GraphQL, or JavaScript. JavaScript anywhere: every property of every component can be bound to JavaScript expressions. Write complex logic using full JavaScript syntax with access to query results, component values, and utility libraries (lodash, moment). State management: components have state that updates reactively when data changes. Workflow automation: create automated workflows triggered by schedules, webhooks, or button clicks. Retool Workflows runs Python or JavaScript code with database queries and API calls. Mobile apps: build mobile-friendly internal apps that work on iOS and Android. Custom components: embed custom React components when built-in components aren't sufficient. On-premise deployment: deploy entirely within your own infrastructure (VPC, on-premise) for data security. Version control with Git integration. Role-based access control. JavaScript/React. Proprietary with free tier.
