Is Retool safe? How to secure your Retool app
Retool builds internal tools fast over your data — the risk is broad database permissions and access control on apps.
Retool is a legitimate internal-tools platform with real security controls. Risk comes from configuration: database resources connected with broad write permissions, queries that interpolate user input, and apps shared more widely than intended. Lock down resource permissions and app access before relying on it.
Retool is a legitimate platform for building internal tools quickly over your databases and APIs, with genuine security features. The risk is configuration: connecting a database resource with broad read/write access, building queries that interpolate raw user input (SQL injection), and sharing apps with more people than intended. Scope resource permissions to least privilege, parameterize queries, and review who can access each app before launch.

The most common Retool security risks
Over-broad resource permissions
A database resource with full write access exposes more than most tools need. Scope credentials to least privilege.
SQL injection via raw input
Queries that interpolate user input directly are injectable. Use parameterized queries.
Wide app sharing
Apps shared organization-wide may reach people who shouldn't see the data. Review access per app.

Retool security FAQ
- Is Retool secure?
- Yes, when configured carefully. Retool has strong security features, but risk comes from broad resource permissions, injectable queries and over-wide app sharing. Apply least privilege before you rely on it.
