Retool

Retool builds internal tools, admin panels, dashboards, CRUD apps, approval workflows, and operational interfaces, that internal teams use to manage data, processes, and operations. It is not for building customer-facing products. Common examples: customer lookup tools for support teams, order management dashboards, KYC review interfaces, and reporting tools.

Retool is low-code, primarily drag-and-drop with a JavaScript escape hatch for custom logic. Most internal tools can be built without writing code. Complex data transformations, conditional logic, and custom API integrations may require JavaScript. The hybrid approach makes Retool accessible to non-engineers while powerful enough for complex use cases.

Retool Free supports up to 5 users with limited features. The Team plan is $10/user/month. The Business plan is $50/user/month with advanced features. Through Retool for Startups, eligible startups get one year free on a monthly Team or Business plan, worth up to $60,000, then 25% off in year two.

Yes. Retool connects to PostgreSQL, MySQL, MongoDB, Microsoft SQL Server, BigQuery, Snowflake, Supabase, Firebase/Firestore, DynamoDB, Redis, Elasticsearch, and 20+ other databases. REST API, GraphQL, and gRPC connectors handle any data source not covered by native integrations.

Retool supports SOC 2 Type II compliance, role-based access controls, audit logs, and SSO. For production data access, use a read replica (not the primary database), restrict write permissions to specific roles, and enable audit logging to track who accessed what data. Retool's self-hosted option provides additional security for sensitive environments.

A basic CRUD tool (table + form + filters): 1-2 hours. A customer admin panel (multi-source data, search, actions): 3-6 hours. A complex workflow tool (approval chains, conditional logic, multi-step forms): 1-2 days. These timelines assume familiarity with Retool, first-time users should add 50% for learning.
