The new Analytics page gives you visibility into workflow health and activity across your organization.

From the workflows landing page, select Analytics to access two views:

• All workflows: Aggregate run counts, failure rates, and resource consumption across every workflow in your organization. Includes a ranked list of your most-run workflows, a Top problem workflows table that surfaces workflows with high failure rates, and resource consumption data for the current month.
• Individual workflow: Drill into a single workflow to review summary stats, run and latency breakdown charts, resource consumption, and a paginated list of recent runs with per-run status and duration.

Retool 3.383 is now available on the Edge release channel for self-hosted organizations.

Admins can now configure memory limits for workflow code execution at the org level, and workflow editors can override those limits on a per-workflow basis.

• Org-level defaults: In Settings, go to the Advanced section and click Advanced settings to set a default memory limit (MB) that applies to all workflow runs in your organization.
• Workflow-level overrides: Open any workflow and go to Settings to override the org default for that workflow.

When a workflow runs a code block, the executor enforces the most specific limit available (workflow > org > server default). If a block exceeds its limit, it fails immediately with a clear error.

Customers who are not configuring limits see no behavior change — the server default of 2,500 MB memory applies. For customers whose workflows were hitting out-of-memory errors, limits can now be tuned without requiring infrastructure changes.

Gemini 3.1 Pro (Preview), Gemini 3 Flash (Preview), and Gemini 3.1 Flash-Lite (Preview) are now available in Retool through Google. They can be used with AI resource queries.

Retool now provides a native integration for ClickHouse, an open-source column-oriented database designed for real-time analytics. You can create a ClickHouse resource and use it to query analytical data with SQL—including ClickHouse-specific functions and aggregations—build dashboards on live data, and insert records from apps and automations.

Retool is phasing out support for MongoDB Server version 3.4 and earlier. Organizations with an unsupported version of MongoDB Server connected to Retool must upgrade to MongoDB Server 3.6 or later.

• For cloud organizations, support for MongoDB Server 3.4 and earlier has already been removed.
• For self-hosted organizations, support for MongoDB Server 3.4 and earlier will be deprecated in the Q2 2026 stable release. It will be removed in the Q3 2026 stable release.

MongoDB Server 3.4 has been end of life (EOL) since January 2020. We recommend upgrading to a currently supported MongoDB release.
