Updates, changes, and improvements at Retool.
Refer to the stable and edge release notes for detailed information about self-hosted releases.
You can now prompt the app building agent to create REST API or PostgreSQL resources directly from the app builder.
Describe the resource that you want to create, and the agent initiates the resource creation process. You'll be asked to provide credentials or more details where applicable.
Retool encrypts all resource credentials and never exposes them to the agent.
Retool now supports the following new AI models for AI resource queries:
The following patches are now available on the Stable release channel:

Organizations on the Team plan can now use Retool-provided AI models for app building, in addition to the full catalog of supported models. These models, prefixed with Retool, have been tuned by Retool for enhanced performance and speed for app building.
If the organization has not set a preferred resource for AI app building, the app building agent will use a Retool-provided model.

Retool has concluded the public beta period for Assist, and Assist is no longer available in the classic app builder for most cloud or self-hosted instances. Certain customers retained access until December 31, 2026, in order to migrate off the tool. If your organization retained access, see Assist for supported models and setup instructions.
The drag-and-drop experience for building and maintaining classic apps is still available. For an AI-powered building experience, Retool recommends using the new app builder. Converting your classic apps to the new app builder is free for Team, Business, and Enterprise organizations.

Starting January 1, 2027, Retool is deprecating Retool Email for organizations on the Free plan. After this date, Free plan organizations can no longer use Retool Email to send emails from apps, workflows, or other automations.
Retool Email remains available to organizations on the Team, Business, and Enterprise plans.
This change affects cloud-hosted organizations on the Free plan that use Retool Email. Organizations on paid plans are not affected.
As part of our continued efforts to keep Retool secure and reduce vulnerabilities, Retool is deprecating several preinstalled third-party libraries, such as jsonwebtoken, crypto-js, moment, and uuid, currently available in custom authentication JavaScript steps. Retool plans to remove these libraries from cloud and self-hosted instances in Q2 2027.
If your custom authentication steps use any of these libraries, you can migrate to Node.js built-in equivalents, such as crypto and Buffer, well ahead of the removal date. Migrating before then avoids any disruption to your authentication flows.
Only REST API, GraphQL, OpenAPI, and gRPC resources that use Custom Auth with a JavaScript step that loads a preinstalled library are affected. JavaScript steps that use Node.js built-in modules, such as crypto, continue to work without changes.
Any customers who have resources that use Custom Auth as its authentication method and one of its JavaScript steps loads a preinstalled library. Custom authentication steps that only use Form (modal), API Request, or Define a variable steps aren't affected, and neither are JavaScript steps that don't call require().
