Retool now supports Apache Kafka. You can use the Kafka integration in apps and workflows to produce, consume, or commit messages to a topic. This integration enables you to respond to events as they occur, triggering changes and actions in your workflows or apps.

You can now connect any AI provider that adheres to the OpenAI, Anthropic, Google, or Cohere schema. This enables you to connect from a wide range of AI providers, such as Mistral, Fireworks AI, Together AI, and OpenRouter.

Organizations with increased security and compliance requirements can also configure custom AI providers if they need to route traffic through their own proxies.

Resources now have additional permission levels. This make it easier to build apps with sensitive data in a secured way.

• The Use permission grants users permission run queries on a given resource. This means administrators can now control access to sensitive resources without needing to control access to different apps.
• For Retool organizations on the Enterprise plan, resource permissions can also be granted at the environment level.

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.

Retool Storage is a hosted blob store that allows you to upload and interact with your files without needing to configure an object store (e.g., S3, Azure File Storage). There is a 5 GB storage limit per organization, with a 40 MB limit on file size. Your browser may have settings that restrict this limit further.

Working with files has previously been a challenge for users as it required storing base64 strings or using third-party data stores. Retool Storage is a built-in solution that requires no configuration.

There are two ways to interact with Retool Storage:

• The Retool Storage section in the Resources tab for your organization.
• The Retool Storage resource, available in both apps and workflows.

You can programmatically upload, read, and download from Retool Storage.

When you configure a resource on cloud instances, you can now choose to route traffic through the eu-central-1 region, based in Frankfurt, Germany, or through the default us-west-2 region, based in Oregon, US. This determines the network round trip time it takes Retool to query your data sources. Selecting a region in close proximity to your resources can improve your application's performance.

You can set a default region for all your resources and override it for individual resources. Learn how to set resource regions in our documentation.

Using the built-in Mobile Push Notifications resource, you can write queries that send push notifications to specific users from any Retool web app, Retool Mobile app, or Retool Workflow via webhook. Contact us to get started or read our push notification docs to learn more.

We’ve added the ability to work with resources and apps that have multiple environments in Retool Mobile using our new environment switcher

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.
