Retool will deprecate the use of YAML for protected apps, queries, and resources in Source Control. Support will be removed in the Q2 2025 stable release of Self-hosted Retool.

Self-hosted organizations still using YAML serialization of these elements in Source Control must migrate to Toolscript prior to upgrading.

Dynamic queries enable users to access several different resources from a single query. These queries decrease the maintenance burden for apps that need to query various similar resources.

Some example use cases for dynamic queries include:

• An app for your support team to interact with customer data when every customer’s data is hosted on a standalone database with unique credentials.
• An admin panel to measure the health of customers’ deploys when every customer has their own tenant.
• A generic budget dashboard for client projects when every client has their own database.

Retool RPC (Remote Procedure Call) allows you to connect your own codebase. Once enabled, you can define functions in your backend and use them within Retool apps and workflows.

Offline mode in Retool Mobile enables users to continue performing read and write actions whenever the internet connection is lost.

Reads: Screens and parts of the app that users have visited while online are cached and available when the device is offline.

Writes: Users can continue performing write actions with cached data. Once the connection is restored, Retool Mobile syncs the changes back to the server.
