Changelog

An open source AI model available through Baseten, Kimi K2 Instruct is now available in Retool. It can be used with AI actions and with Retool Agents.

Retool no longer supports the Llama 4 Maverick or Llama 4 Scout AI models in Retool AI. The Kimi K2 Instruct model will be used instead.

Retool is excited to announce Assist, your AI-powered partner for app development. Prompt Assist with natural language directly from the app IDE to generate apps, make changes to existing apps, and ask questions about Retool.

Assist can:

• Generate full-stack apps from a prompt using your live production data. Retool scaffolds apps based on your real databases and resources.
• Respect all existing org policies by default—SSO, role-based access control, and data-level permissions. Apps remain secure and access-controlled without any manual configuration.
• Edit components, queries, and styles of your existing apps.
• Answer questions about an existing app, including about the purpose of the app and how it works. Assist can also answer questions about Retool in general.
• Deploy AI-generated apps to production without leaving Retool. Hosting, versioning, and monitoring are built-in for cloud and self-hosted deployments.

Retool has released several improvements to the README experience for web apps:

• The README is now located at the top of the Pages or Screens list for easy access.
• You can now use AI to generate a README automatically based on the components and logic of your app.

Previously, app READMEs were found by clicking the title of the app. If your app has an existing README, you can now find it in the Pages tab.

You can now see the output of an agent run with the Result (sync) return type when using the Invoke Agent block in workflows.

• The Result (sync) type is the default setting. This returns the direct result of the agent's output.
• The Run state (async) type returns the agentRunId, agentId, and status only. It does not include the output of the agent.

Claude Sonnet 4.5 is now available in Retool. It can be used with AI actions and with Retool Agents.

Retool no longer supports Gemini 1.5 Pro. Gemini 2.0 Flash will be used instead.

Cloud customers on all plans can now submit breakage reports from inside the product to report regressions, breakages, and potential incidents on the Retool platform.

The breakage form is available by clicking Report a breakage from the following locations:

• The Apps and Resources landing pages, by clicking the chat button on the bottom right corner of the screen.
• The App IDE, by clicking the Help button in the status bar.
• The resource configuration pages, by clicking the Help button in the status bar.
• The Query Library, by clicking the Help button in the status bar.

After you submit a breakage report, you will receive a confirmation email with a ticket number.

The Fullstory integration for session replay is now generally available.

When enabled, data about user interactions with apps are reported directly to Fullstory for you to review in detail. You can then analyze app analytics, evaluate impact, and review interactions with session replay. This integration is useful for monitoring user activity across different apps, and using advanced analytical tools like heatmaps and funnels to identify usage patterns, debug errors, and improve the overall user experience.

Enterprise customers can send page load and query traces to Datadog and Sentry using Retool's performance monitoring integration, now in public beta. Customers can respond proactively to regressions and troubleshoot more quickly by creating dashboards and alerts to monitor the performance of their apps and use the spans themselves to help pinpoint where to take action if their apps are degraded.
